Latino men who have sex with men (MSM) constitute a group at high risk for HIV. Recent approaches to understanding sexual risk have emphasized the role that contextual factors can play in shaping behavior. This study examined sexual behavior of Latino MSM in private and public settings. First, a within-person comparison of behaviors performed in sexual encounters that occurred in public and private settings was conducted. Unprotected anal intercourse (UAI) and other sexual behaviors involving anal stimulation were more common in private settings; group sex was more likely in public settings. Second, a between-person analysis compared sexual behaviors of MSM who went to three different types of public sex settings during the past six months. The types were: (1) commercial sex venues (CSVs), which were defined as businesses with the function of providing a space where MSM can go to have sexual encounters, such as gay bathhouses; (2) commercial sex environments (CSEs), which were defined as businesses with another apparent function, but in which MSM sometimes have sexual encounters, such as gay bars or pornographic movie houses; and (3) public sex environments (PSEs), which were defined as free public areas where MSM can go to find partners for anonymous sex, such as parks or public restrooms. Results indicated that anal sexual behavior was most likely to occur in CSVs and least likely in PSEs, but the probability of UAI was not found to differ among the three types of settings. Behavioral differences were discussed in terms of structural conditions related to privacy and safety, and psychological factors related to intimacy.
与男性发生性关系的拉丁裔男性（男男性行为者）是感染艾滋病毒的高危群体。最近，理解性风险的方法强调了背景因素在塑造行为方面可能发挥的作用。本研究调查了拉丁裔男男性行为者在私密和公共场合的性行为。首先，对在私密和公共场合发生的性接触中所进行的行为进行了个体内部比较。无保护肛交（UAI）和其他涉及肛门刺激的性行为在私密场合更为常见；群交在公共场合更有可能发生。其次，进行了个体间分析，比较了在过去六个月里去过三种不同类型公共性行为场所的男男性行为者的性行为。这三种类型分别是：（1）商业性交易场所（CSV），被定义为具有提供男男性行为者进行性接触空间功能的场所，如同性恋澡堂；（2）商业性交易环境（CSE），被定义为具有其他明显功能，但男男性行为者有时会在其中进行性接触的场所，如同性恋酒吧或色情电影院；（3）公共性行为环境（PSE），被定义为男男性行为者可以去寻找匿名性伴侣的免费公共区域，如公园或公共卫生间。结果表明，肛交行为最有可能发生在商业性交易场所，而在公共性行为环境中最不可能发生，但未发现无保护肛交的概率在这三种场所类型之间存在差异。从与隐私和安全相关的结构条件以及与亲密关系相关的心理因素方面对行为差异进行了讨论。
