Felching (sucking or eating semen out of someone's anus) is a sexual behavior about which virtually nothing has been written in the scholarly literature, despite the fact that it appears to be a not-uncommon practice among certain subpopulations of men who have sex with men (MSM). This study examined three broad research questions: (1) How common is felching? (2) How does a desire for felching relate to other HIV risk practices and risk behavior preferences? (3) What factors are associated with the desire to engage in felching? The data were from a content analysis study of one of the largest Internet websites specifically targeting MSM looking for partners for unprotected sex. A total of 1,316 profiles on the site were analyzed and selected randomly based on users' ZIP codes. Felching was mentioned as a sought-after practice in approximately one-sixth of the men's profiles. Men who wanted to find felching partners were significantly more likely than those not searching for felching partners to seek other types of risky sex, including unprotected oral and unprotected anal sex, and various enhanced risk preferences (e.g., having sex while high, multiple-partner sex, unwillingness to withdraw the penis prior to internal ejaculation). Multivariate analysis revealed several factors that were related to an interest in identifying partners online for felching, including race/ethnicity, indifference to sex partners' HIV serostatus, several sensation-seeking measures (e.g., wanting "wild" or "uninhibited" sex, self-identification as a "bug chaser"), and eroticizing ejaculatory fluids.
吮吸（从某人的肛门中吸出或吃下精液）是一种性行为，尽管它似乎是某些男男性行为者（MSM）亚群体中一种并不罕见的做法，但几乎没有任何学术文献对此进行过描述。本研究考察了三个广泛的研究问题：（1）吮吸有多普遍？（2）对吮吸的渴望与其他 HIV 风险行为和风险行为偏好有何关系？（3）哪些因素与吮吸的欲望有关？这些数据来自对一个专门针对 MSM 寻找无保护性行为伴侣的最大互联网网站之一的内容分析研究。对该网站上的 1316 个个人资料进行了分析，并根据用户的邮政编码随机选择。大约六分之一的男性个人资料中提到了渴望吮吸的行为。与那些不寻找吮吸伴侣的男性相比，那些希望找到吮吸伴侣的男性更有可能寻求其他类型的高危性行为，包括无保护的口交和无保护的肛交，以及各种增强的风险偏好（例如，在兴奋时进行性行为、多伴侣性行为、不愿意在内部射精前拔出阴茎）。多变量分析显示，有几个因素与在网上寻找吮吸伴侣的兴趣有关，包括种族/民族、对性伴侣 HIV 血清阳性的漠不关心、几种寻求刺激的措施（例如，想要“狂野”或“不受约束”的性行为、自我认同为“寻毒者”），以及对射精液的色情化。
