Sex on premises venues (SOPVs) where men have sex with men have been implicated in the spread of sexually transmissible infections, but few studies have described men's sexual encounters in SOPVs, particularly the degree to which men from different backgrounds engage in risky sexual practices.
Interviewer administered surveys were conducted with 186 Australian men who have sex with men (MSM) within 48 h of visiting an SOPV. They reported their sexual practices, the characteristics of their partners and other circumstances surrounding their sexual encounters.
All analyses were based on the number of sexual encounters (n = 430). Oral sex was the most common practice, occurring in 74.9% of encounters, followed by massage, frottage or kissing (53.7%), solo or mutual masturbation (36.3%), and anal sex (32.1%). Multivariate analyses revealed age as a significant factor for having protected anal sex (P = 0.001), insertive anal sex (P = 0.004) and receptive anal sex (P < 0.001). These practices were more frequent in encounters among younger men, while masturbation (P = 0.03) was more frequent among older men. When men's sexual partners were affected by alcohol, encounters were less likely to involve unprotected anal intercourse (P = 0.006) and more likely to involve massage, frottage or kissing (P = 0.009). Men disclosed their HIV status in only 7.7% of encounters.
With the likelihood of risky sexual practices varying according to background, results from this study should be used to guide interventions aiming to promote safer sex in SOPVs.
男男性行为场所（SOPV）被认为与性传播感染的传播有关，但很少有研究描述男男性行为场所中男性的性接触情况，特别是不同背景的男性参与危险性行为的程度。
在男男性行为者（MSM）访问SOPV后48小时内，对186名澳大利亚男男性行为者进行了访谈式调查。他们报告了自己的性行为、性伴侣的特征以及性接触的其他相关情况。
所有分析均基于性接触次数（n = 430）。口交是最常见的性行为，在74.9%的性接触中发生，其次是按摩、摩擦或亲吻（53.7%）、自慰或相互手淫（36.3%）以及肛交（32.1%）。多变量分析显示，年龄是进行安全性行为（P = 0.001）、插入式肛交（P = 0.004）和接受式肛交（P < 0.001）的一个重要因素。这些行为在年轻男性的性接触中更为频繁，而手淫（P = 0.03）在年长男性中更为频繁。当男性的性伴侣受酒精影响时，性接触中发生无保护肛交的可能性较小（P = 0.006），而进行按摩、摩擦或亲吻的可能性较大（P = 0.009）。男性仅在7.7%的性接触中披露了自己的艾滋病毒感染状况。
由于危险性行为的可能性因背景而异，本研究结果应用于指导旨在促进SOPV中安全性行为的干预措施。
