            <title>Introduction</title>
            <p>Since the emergence of HIV and the AIDS pandemic, sex workers were considered a highly vulnerable group
                <sup>
                    <xref ref-type="bibr" rid="ref1">1</xref>
                </sup> because of their high-risk exposure to acquire these infections compared to adult non-sex workers.
                <sup>
                    <xref ref-type="bibr" rid="ref2">2</xref>
                </sup> Across the globe, approximately 8% of the newly HIV cases are reported among sex workers.
                <sup>
                    <xref ref-type="bibr" rid="ref3">3</xref>
                </sup> Of serious concern are male sex workers (MSW) who are at more HIV risk than female sex workers (FSW). Receptive anal intercourse and insertive anal intercourse are considerably at higher risk of HIV transmission than vaginal sex.
                <sup>
                    <xref ref-type="bibr" rid="ref4">4</xref>
                </sup> Further, MSW are greatly affected by other sexually transmitted infections (STIs).
                <sup>
                    <xref ref-type="bibr" rid="ref5">5</xref>

                <sup>
                    <xref ref-type="bibr" rid="ref7">7</xref>
                </sup> In response to AIDS and the concurrent increase in HIV prevention research, numerous interventions that aimed at decreasing the risk of infection have been conducted to reduce the practice of condomless sex.
                <sup>
                    <xref ref-type="bibr" rid="ref8">8</xref>

                    <xref ref-type="bibr" rid="ref11">11</xref>
                </sup> After decades, there is still a debate about the success of these interventions - while some authors claim that new infections are yet associated to an inconsistent use of condoms,
                <sup>
                    <xref ref-type="bibr" rid="ref12">12</xref>

                </sup> others argue that MSW are using them more regularly, for either insertive anal sex or receptive anal sex.

            <p>A large number of sex workers in Europe are migrants who are living and working in disadvantaged circumstances, facing isolation and social exclusion.

                </sup> in some European countries. For example, it has been reported that male street sex workers, in particular illegal migrants in Germany, have lack of access to health care services due to their socio-legal position.
                <sup>
                    <xref ref-type="bibr" rid="ref23">23</xref>
                </sup> This is a significant aspect as non-European sex workers who are highly mobile in Europe

                    <xref ref-type="bibr" rid="ref19">19</xref>
                </sup> and are under different migration status,

                    <xref ref-type="bibr" rid="ref24">24</xref>
                </sup> can be impacted by the legislation and internal policies of each country that determines their access to the health care services.
                <sup>
                    <xref ref-type="bibr" rid="ref17">17</xref>
                </sup> In the United Kingdom, an important proportion of the sex work population is represented by male migrant sex workers (MMSW) who mostly work indoors in London.
                <sup>

                </sup> Epidemiological and qualitative research have demonstrated that these migrants utilize national health care services (NHS), including sexual health clinics. In this manner, they can be tested for HIV and other STIs, receive counselling, adequate information, and a provision of condoms and lubricants.
                <sup>

                </sup> However, a study using national data demonstrated that although the use of sexual health clinics does not vary between British MSW and MMSW, the latter group seem to be more exposed to HIV and chlamydia infections.

                </sup> In this manner, this paper aims to contribute to lessons learnt and recommendations for future educational interventions for this highly vulnerable group. This paper is pertinent in an era when the role of behavioral interventions is evolving with the advent of efficient alternatives of prevention such as pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP). Despite of the efficacy demonstrated by the PrEP scheme, it requires high adherence to the treatment, strict laboratory monitoring,

                    <xref ref-type="bibr" rid="ref33">33</xref>
                </sup> and more importantly, the use of supplementary methods of prevention such as the use of condoms to further reduce the HIV risk, and specifically for protection against other STI; since PrEP only protects against HIV.

                <p>This qualitative research was carried outed between May 2013 to August 2015. Convenience sampling method was used to recruit men aged 18 and over, who were non-British, lived in the country for at least one year, and who had worked or were still working as sex workers. The main recruitment sites were sexual health clinics and projects that provide health and social services to sex workers in London. Health professionals and health workers took part in the recruitment by providing the participant information sheet (PIS) and flyers to potential participants.</p>

Participants were interviewed in counselling rooms and small meeting rooms located in St. Marys hospital and City, University of London to secure their privacy. Literal transcription of the recordings was printed and revised by each participant to confirm their accuracy. In this manner, the risk of misinterpretation and misunderstanding was minimised.

For this investigation, 'condomless sex' was defined as any penetrative or receptive sexual intercourse (oral, vaginal, or anal) without using condoms. Conversely, 'safer sex' was specified as the use of condoms for the aforementioned practices. The emergent themes were interpreted using the theory of planned behavior (TPB)

                    <bold>A. Condomless sex with commercial sexual partners</bold>
                </p>
                <p>This theme explains the perspective of the use of condoms within the context of sex work and experiences of condomless sex that contains three sub-themes:</p>
                <p>1. Policy on condom use with clients</p>
                <p>It describes the attitude and perceived norm about the use of condoms with clients. The statements indicate that the entire group of participants were aware of the HIV and other STIs, claimed to be risk averse, and more importantly, stated a consistent use of condoms as a perceived norm because of their work. In line with this, many of them have made explicit their rejection to condomless sex in their online adverts:</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;Always, always condom, nothing without a condom, never, ever, ever. They can pay me any money, there are some offers, and some people asked me - do you do [condomless sex]? For that reason, in my profile I wrote no [condomless sex], don&#x2019;t even ask me&#x201d;</italic>
                    </p>
                </disp-quote>
                <p>Consistently, the majority of participants expressed a favourable attitude towards safer sex. For some, using condoms with clients was a way to differentiate sexual services from having sex in their personal life. Others thought that condoms were useful devices to avoid poor hygiene, odour, and some bodily features of clients that they find unattractive or dislike (e.g., overweight, excessive corporal hair). Most of the participants said that they especially demand the use of condoms to provide services such as vaginal intercourse, &#x2018;full-service&#x2019; for men (usually include anal sex) and performing &#x201c;passive&#x201d; sexual role service (receptive anal sex):</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;I offer a full service, a complete service but I try to be specific because people always ask you if you do without condom, So I always say condom, I won&#x2019;t give you my phone, I am a very discrete person and I only do outcalls.&#x201d;</italic>
                    </p>
                </disp-quote>
                <p>By contrast, other participants admitted an unfavourable attitude towards condoms. While the most mentioned concerns of losing clients that reject condoms, few did not like their use as it reduced their sexual arousal, especially with erection which caused difficulties in their sexual performance:</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;I know that I won&#x2019;t have many clients if I insist on having oral sex with a condom, so I prepare to take that risk that is the only one that I prepare to take the chances.&#x201d;</italic>
                    </p>
                    <p>
                        <italic toggle="yes">&#x201c;I don&#x2019;t enjoy at all when I use a condom for [oral sex] because it is like you are sucking a rubber and I just get soft</italic> [lose the erection] 
                        <italic toggle="yes">when I wear a condom for a [oral sex], once again it is because of it something like squeeze it is a bit weird.&#x201d;</italic>
                    </p>
                </disp-quote>
                <p>The discrepancy between these two different perspectives suggests that risk awareness and intention of using condoms do not guarantee safer sex.</p>
                <p>In addition, the analysis of the narratives showed that condomless sex with clients occurred in two different scenarios. In the first scenario participants perceived control of the situation and made a risk-taking decision to dismiss the use of condoms, and in the second, they lost control of the situation that ended in a condomless sex event. These are described under the following sub-themes:</p>
                <p>2. Decision-making process to accept condomless sex</p>
                <p>This sub-theme explains the decision-making process that participants applied to dismiss the use of condoms with clients. They used two main processes a risk assessment of the clients, and performing sexual practices that participants catalogued as 
                    <italic toggle="yes">'low-risk'</italic> in contracting HIV and other STIs. The participants assessed the risks of the client based on their physical appearance, followed by a subtle physical examination to identify sores, warts or blisters on genitals or rectum, or presence of penile discharge. Through this practice participants accepted condomless sex with customers that were labelled as 
                    <italic toggle="yes">&#x2018;healthy&#x2019;</italic> and 
                    <italic toggle="yes">&#x2018;clean&#x2019;</italic> (e.g., absence of warts):</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;I [had sex with] him all without condom, but I was not a risk as I could tell that I was probably the second or third person who he has sex with. I think I could tell about everything I do not think he has anything because he probably has very little sexual life.&#x201d;</italic>
                    </p>
                </disp-quote>
                <p>The participants also considered some social and demographic characteristics to rank clients as 
                    <italic toggle="yes">'low risk'</italic> or 
                    <italic toggle="yes">'high risk'.</italic> In this instance, participants favoured clients who were 
                    <italic toggle="yes">'married men'</italic> for condomless sex as they were perceived as 
                    <italic toggle="yes">&#x2018;straight&#x2019;</italic> men who 
                    <italic toggle="yes">&#x2018;only have sex with their wives.&#x2019;</italic> In the same way, participants considered their 
                    <italic toggle="yes">&#x2018;regular&#x2019;</italic> clients with whom they had established a long-term and trustworthy relationship, as &#x2018;low risk&#x2019;:</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;For example, yesterday I had a man from Barbados who looked very healthy, but I know he is from a high-risk region for these diseases. The guy was very clean, he was very nice&#x201d;</italic>
                    </p>
                    <p>
                        <italic toggle="yes">&#x201c;There are a couple of people that I don&#x2019;t use a condom because I know them for quite long time. I know it is not a good policy. I know I should use a condom with everybody and that&#x2019;s it, but there are few people that I do that.&#x201d;</italic>
                    </p>
                </disp-quote>
                <p>A second procedure to accept condomless sex with clients was the selection of sexual practices that participants considered as 
                    <italic toggle="yes">'low-risk.'</italic> By far, condomless oral intercourse (COI) was the most frequent practice. Some participants mentioned that as additional strategies of protection they reduce the time for COI and avoid contact with the client&#x2019;s semen. Although, condomless insertive oral intercourse (CIOI) and condomless receptive oral intercourse (CROI) were equally reported by participants, some assigned different levels of risk to each:</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;I know it is less risky when I suck him than when he sucks me or to kiss him. But it is not for everybody, depend on of the situation&#x201d;.</italic>
                    </p>
                </disp-quote>
                <p>Another recurrent risk reduction practice mentioned was performing condomless anal sex as the active sexual role (penetrative anal intercourse) instead of a passive role (insertive anal intercourse), as it was perceived as less risky:</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;Part of me think I am mainly top, I normally do not get people to [have sex with] me, I [have sex with] them, I am mainly top, and that is a very low risk,</italic> [censored]
                        <italic toggle="yes">! I am not at risk because it is the very little rate to catch something if I am mainly top.&#x201d;</italic>
                    </p>
                    <p>
                        <italic toggle="yes">&#x201c;I think, I am in this scene, I am earning money, but I am also scared because this is very risky, but I always pray to God please nothing bad happen.&#x201d;</italic>
                    </p>
                </disp-quote>
                <p>3. Structural factors determining unplanned condomless anal sex</p>
                <p>This sub-theme describes the role of four main factors that made participants to 
                    <italic toggle="yes">'lose control'</italic> or to be under pressure to perform condomless anal intercourse. One of the most recurrent conditions was the use of recreational drugs that provoked a strong sexual arousal among participants. Many of these events occurred when they were providing 
                    <italic toggle="yes">&#x2018;overnight' or 'chemsex&#x2019;</italic> services:</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;With crystal meth your brain is still more there, but with mephedrone you do not even think straight so much, you are so</italic> [aroused] 
                        <italic toggle="yes">that you do not even think, you only want sex, if I take mephedrone I know I am not going to use condoms&#x201d;</italic>
                    </p>
                </disp-quote>
                <p>A second recurrent and independent condition was feeling strong attraction to a client:</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;Actually, I wasn&#x2019;t on drugs, this time I wasn&#x2019;t on drugs, I came to see this guy in the Ritz Hotel, and he was an Arabic, he was about my age, and he was so gorgeous! Sexy, he was like my God! I just wanted to eat him alive, he was so sexy and then, you know what actually I did it without condom&#x201d;</italic>
                    </p>
                </disp-quote>
                <p>A third factor driving condomless anal sex was the financial reward offered by clients, which was mostly reported by participants who were in precarious conditions. In these situations, the participants felt that they could not reject the offer:</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;I had a client once, the same client three times because that client, he pays very well, much more that what I asked&#x201d;.</italic>
                    </p>
                    <p>
                        <italic toggle="yes">&#x201c;I am at risk if you ask me how I feel about it, not very safe, not very clever. But I gamble for the best, I need the cash, I need the cash for food, I need the cash for transport, and I need to get out of this hole because I smile when I meet new people and everything, but when I am alone is not easy.&#x201d;</italic>
                    </p>
                    <p>
                        <italic toggle="yes">&#x201c;Once I was really bad about money and a client called me and he wanted to take drugs also if you don't take drugs, you can last all that you need or you can even cope with the client.&#x201d;</italic>
                    </p>
                </disp-quote>
                <p>The fourth condition describes scenarios in which participants were overpowered by clients who removed or broke condoms or took advantage of the dynamic during the sex session to perform condomless anal intercourse. This condition was usually reported by the participants who offer a &#x2018;passive&#x2019; sexual role as part of their sexual services:</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;I was having sex with a guy who was doing as active, and you know suddenly I saw him with the condom on his hand and I asking him, &#x2018;Were you [having sex with] me without a condom?!&#x201d;</italic>
                    </p>
                </disp-quote>
                <p>In few cases, participants reported that these events occurred in a context of physical and verbal violence perpetrated by clients, or within a context of drugs use:</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;We were taking cocaine and drinking, I drank so much that day and I passed out [&#x2026;] few hours later, I woke up and the reason that I woke up was because something was painful, ok?

                    </p>

                <p>
                    <bold>B. Condomless sex with non-commercial sexual partners</bold>
                </p>
                <p>This theme describes experiences of unpaid or non-commercial condomless sex, which was defined as sexual acts without the use of condoms that were performed without any intention of material or economic reward. In general, many participants declared a more inconsistent use of condom with non-commercial sexual partners than with clients:</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;Then it happened again, but he wasn&#x2019;t a client he was a person that I met, a casual partner and again it was three months of waiting for the test and I was - Oh my God, I shouldn&#x2019;t do it again!&#x201d;</italic>
                    </p>
                    <p>
                        <italic toggle="yes">&#x201c;I haven&#x2019;t been in risk. My sexual practices are very low risk in the context of work, and the only person with I have been in high risk is with my ex-partner.

                    </p>
                </disp-quote>
                <p>This theme contains two sub-themes to differentiate condomless sex practice with formal sexual partners from casual sexual partners. Most of the participants reported having casual partners along with a formal partner in the past year.</p>
                <p>The sub-themes are described below:</p>
                <p>1. Condomless anal sex with formal partner</p>
                <p>The category of formal sexual partner was used by participants to describe people with whom they had a romantic, stable/regular or committed relationship. Almost half of the group reported to have male formal sexual partners. Some mentioned that these partners were also working as escorts, even few worked together. Most importantly, majority reported an irregular or complete lack of condom use with these partners. They decided not to use condoms when their partners agreed to just have sex with them, and/or knew both were HIV negative:</p>
                <disp-quote>
                    <p>
                        <italic toggle="yes">&#x201c;When I am dating someone if we both checked [got tested for HIV] and we both are fine, we do not use condom, like my ex that we split up two months ago, we were together for a year as we never use condoms, but I knew he only was sleeping with me&#x201d;</italic>
                    </p>
                </disp-quote>
                <p>For these participants condomless anal sex represented pleasure, intimacy, and commitment with their partners:</p>

                        <italic toggle="yes">&#x201c;Have sex without condom with my ex-partner wasn&#x2019;t good idea, even if that gives me more pleasure and it gives me more intimacy because sex between us hasn&#x2019;t been the most important part of our relationship&#x201d;</italic>
                    </p>

                <p>Casual sexual partner was defined as people with whom participants engaged in sexual intercourse without a sense of commitment or emotional attachment. They mainly met casual partners using dating mobile applications, websites or in places such as clubs, saunas, or clubs. These participants decided not to use condom with these partners to satisfy their pleasure and personal enjoyment. Some admitted that they perceived the use of condom was optional:</p>

            <p>This study has used the theory of planned behaviour to explore the risk perception and condomless sex experiences of 25 male migrant sex workers with commercial and non-commercial sexual partners. Unlike other research,

                    <xref ref-type="bibr" rid="ref39">39</xref>
                </sup> the participants of this study knew the risks of HIV and other STIs, self-reported risk adverse, and consistently declared their position against condomless sex in their online adverts. However, despite their perception of safer sex as a norm and their intention of using condoms with clients, they revealed that condomless sex was a frequent practice.

                </sup> In accordance with this, the participants exposed an unfavourable attitude towards condoms due to displeasure, concerns of losing clients that reject condoms, and issues affecting their sexual response and performance. The latter, not so often acknowledged, highlights the importance of male sexual arousal in this type of work.

                </sup> In addressing past events of condomless sex with clients, this study identified a perceived behavioural control among participants that made this high-risk decision based on signs of physical evidence for HIV and other STIs in clients, assessing client&#x2019;s social and sexual risk characteristics, and performing sexual practices that they considered 'low risk', to lessen the risk of transmission. These practices, that indicate a self-protective behaviour, demonstrate the persistence of inaccurate information about HIV and other STIs.

            <p>Within the context of private life, this study found that differences in the perspective of condomless sex was related to the type of non-commercial sexual partner. As such, most of participants dismissed the use of condoms with formal partners as they were emotionally attached to these relationships. Participants also said that they agreed not to use condoms when they both were HIV negative and keep this practice strictly among themselves. Although condomless sex with formal partners was perceived as a safer practice, some participants had episodes of STIs that were associated to these sexual partners. Besides, it is worth noting that in line with other studies

Regarding condomless sex practice with casual sexual partners, participants said that it was more frequent with these sexual partners than with their clients. They connected this practice to strong sexual arousal and the use of drugs and alcohol. Drug use mainly initiates sexual interaction between gay and bisexuals,

            <p>Overall, participants that experienced condomless sex visited sexual health clinics to have screening tests for HIV and other STIs, as they felt exposed to contracting these infections. The most concern and anxiety was expressed for HIV, therefore almost all participants had requested for post-exposure prophylaxis (PEP) to reduce their chances of contracting this infection.

                <p>Interpretation of the findings and the evaluation of their significance should be made considering the limitations of this study. For instance, the study design prevents the generalization of the findings. Also, limiting the recruitment of participants to sexual health clinics and health projects in London due to the recommendation of the research ethics committees, restrict the results only to the perspective and experiences of migrants who attend these services. Even with these limitations, this study is one of the few on male migrant sex workers in the UK that captures their experiences of high-risk sexual behaviour in detail. In addition, the heterogeneity of the sample provided a rich qualitative data on MMSW&#x2019;s risky sexual behaviour with commercial and non-commercial sexual partners. Furthermore, this study provides in-depth socio-behavioural insights for designing more effective and tailored interventions for MMSW self-identified as homosexuals and bisexuals.</p>

            <title>Conclusions</title>
            <p>Participants experienced condomless sex with commercial sexual partners as risk-taking decision that intuitively triggered a set of risk reduction practices, which may not work effectively as they were based upon misinformation. Condomless sex with clients also occurred in a context of perceived loss of control with recreational drug use, experiencing precarious conditions, physical domination and verbal violence perpetrated by clients. These findings challenge claims that recreational drugs are not problematic among male escorts,

            <title>Recommendations</title>
            <p>The findings suggest the need to reinforce educational interventions to deliver appropriate information about the transmissibility of HIV and other STIs, improve skills of self-control, strengthen the risk-reduction counselling for those requesting PEP, and the use of condoms for those who decide to take pre-PEP as the best action to secure its success. Likewise, emphasising the relevance of training healthcare professionals to identify MMSW who use recreational drugs, and to facilitate their referral to programmes of harm reduction in substance use and mental health services. Finally, the identification of other subgroups among MMSW such as those whose partners are also sex workers, have a HIV serodiscordant partner, tend to have condomless sex with casual sex partners, and are experiencing difficult-living or working conditions, can allow for tailoring behavioural interventions.</p>

            <p>This is an interesting report about a relevant topic for the UK and worldwide. To make it more suitable for indexing, however, a few issues should be resolved:

                    <list-item>
                        <p>The most visible one is the slang of the quotations (of migrant male sex workers who don't speak English as a first language). Probably there are guidelines as to how they should be edited.</p>

                    <list-item>
                        <p>Likewise, there are some issues with the English language writing of the main text that limit its clarity and should be resolved.</p>
                    </list-item>
                    <list-item>
                        <p>The MMSW quotations should ideally include a code assigned to each participant, as well as their nationality. That would help interpreting the findings.</p>

                        <p>The introduction fails to contextualize the discussions in a framework of combination HIV prevention. Treatment as prevention (and U=U, that is viral suppression as risk-reducing) is never mentioned, PEP is mentioned once, and PrEP is presumably mentioned ("pre-PEP") in the recommendations only.

                        <p>In A.1, when describing unfavourable attitudes towards condoms: (a) the authors inappropriately use condom use in oral sex to illustrate the dilemmas of condom use, while it is not that relevant given its very low risk; (b) authors conflate MSW's fear of others rejecting condoms, with their own predisposition against condoms - those should be presented separately, although certainly with regard to anal, not oral sex.</p>

                    <list-item>

                    <list-item>
                        <p>The discussion should address other options of combination HIV prevention. Either at the introduction or at the discussion, current access to treatment, PEP and PrEP should be discussed as alternatives to condom use.</p>

                <p>Dear Carlos,&#x00a0;</p>
                <p> </p>
                <p> Thanks very much for your comments and suggestions that helped me to improve the paper. Please see my answers below:</p>
                <p> </p>
                <p> Reviewer comment: The most visible one is the slang of the quotations (of migrant male sex workers who don't speak English as a first language). Probably there are guidelines as to how they should be edited.</p>
                <p> 
                    <italic>Author answer: the quotes have been edited by the editorial team of this journal according to their internal policies. In this manner, some words have been removed (as state the disclaimer section (in Results)</italic>
                </p>
                <p> Reviewer comment: Likewise, there are some issues with the English language writing of the main text that limit its clarity and should be resolved.</p>
                <p> 
                    <italic>Author answer: The text has been amended to improve their clarity. </italic>
                </p>
                <p> Reviewer comment: The MMSW quotations should ideally include a code assigned to each participant, as well as their nationality. That would help interpreting the findings.</p>
                <p> 
                    <italic>Author answer: variables as age, pseudonym and country of birth were part of the initial version of this manuscript, but they were removed by the editorial team of this journal. I will be happy to restore this information if they agree to this.</italic>
                </p>
                <p> Reviewer comment: The introduction fails to contextualize the discussions in a framework of combination HIV prevention. Treatment as prevention (and U=U, that is viral suppression as risk-reducing) is never mentioned, PEP is mentioned once, and PrEP is presumably mentioned ("pre-PEP") in the recommendations only. It is unclear whether people who are having condomless sex are really out of any form of protection.</p>
                <p> 
                    <italic>Author answer: I really appreciate this suggestion that open an interesting scope for further research. However, it is important to mention that the data collection for this study took place between 2013-2015, while PrEp and PEP initiatives were increasingly available &#x00a0;since 2016. Participants who had access to them was mostly because were part of trials.</italic>
                </p>
                <p> Reviewer comment: In that sense, the dates of implementation of this study should be specified, for better interpretation of the context.</p>
                <p> 
                    <italic>Author answer: This info has been updated in abstract and methods section&#x00a0;</italic>
                </p>
                <p> </p>
                <p> Reviewer comment: In A.1, when describing unfavourable attitudes towards condoms: (a) the authors inappropriately use condom use in oral sex to illustrate the dilemmas of condom use, while it is not that relevant given its very low risk; (b) authors conflate MSW's fear of others rejecting condoms, with their own predisposition against condoms - those should be presented separately, although certainly with regard to anal, not oral sex.</p>
                <p> 
                    <italic>Author answer: I understand this point, however, condomless sex was examined as an approach for HIV-STI prevention. </italic>
                </p>
                <p> Reviewer comment: The theory of planned behaviour should be used at least in the discussion.</p>
                <p> 
                    <italic>Author answer: Discussion section has been amended to satisfy this suggestion.</italic>
                </p>
                <p> </p>
                <p> Reviewer comment: The discussion should address other options of combination HIV prevention. Either at the introduction or at the discussion, current access to treatment, PEP and PrEP should be discussed as alternatives to condom use.</p>
                <p> 
                    <italic>Author answer: the introduction section has been amended to satisfy this recommendation.</italic>

            <p>Understanding how male sex workers make decisions about condom usage with clients and in their personal sexual lives is an important question that this study addresses. Recent studies have explored this topic in some detail. This study aims to contribute by interviewing migrant male escorts in London and offering explanations that delve into why sex with a condom occurs or not in their encounters with clients.</p>
            <p> </p>
            <p> This is an interesting paper, but there are several gaps:</p>
            <p> </p>
            <p> First, the literature review is not complete. I suggest the author read the recent work by John Scott and his colleagues on male sex work: see 
                <italic>The Routledge Handbook of Male Sex Work, Culture and Society</italic> published by Routledge this year to better grasp the literature on this topic.</p>
            <p> </p>
            <p> Second, could the author expand on new insights for public health campaigns concerning PrEP and HIV prevention that&#x00a0;emerge from this study, and better argue how the results of this study further advance knowledge on the topic of condom use and safe sex among male escorts and particularly vulnerable groups like migrant sex workers?</p>
            <p> </p>
            <p> Third, some methodological issues require addressing. What topics were included on the interview guide? How were the interviews conducted? Can more detail be given about how the data themes were developed and what sort of qualitative data analysis was used?&#x00a0;</p>
            <p> </p>
            <p> Finally, what new insights for public health campaigns emerge from this study?</p>
            <p>Is the work clearly and accurately presented and does it cite the current literature?</p>
            <p>Partly</p>
            <p>If applicable, is the statistical analysis and its interpretation appropriate?</p>
            <p>Not applicable</p>
            <p>Are all the source data underlying the results available to ensure full reproducibility?</p>
            <p>Yes</p>
            <p>Is the study design appropriate and is the work technically sound?</p>
            <p>Partly</p>
            <p>Are the conclusions drawn adequately supported by the results?</p>
            <p>Yes</p>
            <p>Are sufficient details of methods and analysis provided to allow replication by others?</p>
            <p>Partly</p>
            <p>Reviewer Expertise:</p>
            <p>sex work, qualitative data analysis</p>
            <p>I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard, however I have significant reservations, as outlined above.</p>
