Recent research suggests that viewing sexually explicit media (SEM), i.e., adult videos, may influence sexual risk taking among men who have sex with men. Despite this evidence, very little is known about the content of gay male SEM on the Internet, including the prevalence of sexual risk behaviors and their relation to video- and performer-characteristics, viewing frequency, and favorability. The current study content analyzed 302 sexually explicit videos featuring male same-sex performers that were posted to five highly trafficked adult-oriented websites. Findings revealed that gay male SEM on the Internet features a variety of conventional and nonconventional sexual behaviors. There was a substantial prevalence of unprotected anal intercourse (UAI) (34 %) and was virtually the same as the prevalence of anal sex with a condom (36 %). The presence of UAI was not associated with video length, amateur production, number of video views, favorability, or website source. However, the presence of other potentially high-risk behaviors (e.g., ejaculation in the mouth, and ejaculation on/in/rubbed into the anus) was associated with longer videos, more views, and group sex videos (three or more performers). The findings of high levels of sexual risk behavior and the fact that there was virtually no difference in the prevalence of anal sex with and without a condom in gay male SEM have important implications for HIV prevention efforts, future research on the role of SEM on sexual risk taking, and public health policy.
最近的研究表明，观看色情媒体（SEM），即成人视频，可能会影响男男性行为者的性冒险行为。尽管有这方面的证据，但对于互联网上的男同性恋色情媒体的内容，包括性行为风险的流行程度及其与视频和表演者特征、观看频率和喜好的关系，人们知之甚少。本研究对发布在五个高流量成人网站上的 302 个男同性恋色情视频进行了内容分析。研究结果显示，互联网上的男同性恋色情媒体具有多种传统和非传统的性行为。无保护肛交（UAI）的流行率相当高（34%），几乎与使用避孕套的肛交流行率相同（36%）。UAI 的存在与视频长度、业余制作、视频观看次数、喜好程度或网站来源无关。然而，其他潜在高风险行为（如口交、射精在口腔内、射精在肛门内或摩擦肛门）的存在与视频长度较长、观看次数较多以及有三个或更多表演者的群交视频有关。这些性行为风险水平较高的发现，以及男同性恋色情媒体中使用和不使用避孕套的肛交流行率几乎没有差异，这对艾滋病预防工作、未来关于 SEM 对性冒险行为的作用的研究以及公共卫生政策具有重要意义。
