OBJECTIVE
Gay, bisexual, and other men who have sex with men (GBMSM) remain at high risk of HIV infection via condomless anal sex. Sexually explicit media (SEM) likely influences GBMSM's sexual behavior and has been associated with condomless anal sex. SEM messages may be especially potent during formative developmental periods.
METHOD
We examined the association between age of first SEM exposure and condomless anal sex in a sample of adult GBMSM (N = 1,114) recruited using the Internet.
RESULTS
Every 1-year delay in age of first SEM exposure resulted in a 3% decrease in the odds of engaging in condomless anal sex as an adult (odds ratio = .97, 95% CI [.95, .99], p = .01). This association remained significant in 3 separate multivariable models that controlled for age of sexual debut, age of anal sex debut, and current age, respectively. This association was moderated by ethnicity such that the effect was stronger among Latino men.
CONCLUSIONS
GBMSM who were exposed to SEM earlier in their lives report more sexual risk behavior as adults. SEM exposure in GBMSM is an important sexual development milestone deserving further research. (PsycINFO Database Record (c) 2018 APA, all rights reserved).
目的
男同性恋、双性恋和其他与男性发生性关系的男性（GBMSM）仍然存在因无保护肛交而感染艾滋病毒的高风险。色情媒体（SEM）可能会影响 GBMSM 的性行为，并且与无保护肛交有关。SEM 信息在形成性发展时期可能特别有效。
方法
我们在使用互联网招募的成年 GBMSM （N = 1114）样本中，研究了首次接触 SEM 的年龄与无保护肛交之间的关联。
结果
首次接触 SEM 的年龄每延迟 1 年，成年时发生无保护肛交的几率就会降低 3%（优势比=.97，95%置信区间 [.95，.99]，p =.01）。在分别控制性初潮年龄、肛交初潮年龄和当前年龄的 3 个单独的多变量模型中，这种关联仍然显著。这种关联受到种族的影响，这种影响在拉丁裔男性中更为明显。
结论
在他们的生活中更早接触 SEM 的 GBMSM 报告更多的性风险行为作为成年人。SEM 对 GBMSM 的暴露是一个重要的性发展里程碑，值得进一步研究。（PsycINFO 数据库记录（c）2018 APA，保留所有权利）。
