Felching was mentioned as a sought-after practice in approximately one-sixth of the men’s profiles. A total of 1,316 profiles on the site were analyzed and selected randomly based on users’ ZIP codes. 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. 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).
