DIFFERENCES IN HIV RISK PRACTICES SOUGHT BY SELF-IDENTIFIED GAY AND BISEXUAL MEN WHO USE INTERNET WEBSITES TO IDENTIFY POTENTIAL SEXUAL PARTNERS.

Men who have sex with men (MSM) account for the largest number of persons diagnosed with AIDS in the United States, with higher-than-average rates of drug use and unprotected sex being cited as the principal reasons underlying their high rates of HIV infection. Recent evidence has suggested that the use of Websites specifically designed to promote unsafe sexual practices (e.g., Bareback.com, BarebackRT.com, Bare4ever.com) may be particularly common among MSM, thereby fostering their risky behaviors. In light of these findings, the present study, which compares HIV risk behaviors sought by self-identified gay and bisexual men, is based on a content analysis of 1,316 ads/profiles posted on one of the most popular men who have sex with other men (MSM) Websites (namely, Bare-back.com) that specifically fosters unprotected sex. Ads/profiles were selected randomly based on the American ZIP code of residence. Data were collected between September 2006 and January 2007. Rates of advertised-for high-risk sexual behaviors were very high for gay and bisexual men alike, particularly for oral sex involving ejaculation into the mouth, anal sex involving ejaculation into the anus, multiple partner sex, and felching (i.e., eating ejaculatory fluid out of an anus into which at least one person previously ejaculated). Analytical comparisons of gay and bisexual men showed that, on various dimensions, the bisexual men in this sample had either similar or lower levels of sexual risk compared to the gay men. The HIV intervention-related implications of these findings are discussed.
