Barebacking Among Internet Based Male Sex Workers David S. Bimbi, MA Jeffrey T. Parsons, PhD SUMMARY. Some have raised concern that male sex workers (MSWs) serve as “vectors of transmission” of HIV into the heterosexual community. Research on MSWs, however, has found that these men report unsafe sex more often with casual partners than with clients. In the mid-1990s, two new phenomena emerged: the Internet, providing a new way for MSWs to meet clients, and barebacking or intentional anal sex without condoms. Us- ing qualitative and quantitative methods in an effort to understand the im- pact of these phenomena, this study sought to explore intentions for unsafe sex among MSWs who reach clients through the Internet. Findings suggest that most MSWs do not intentionally seek out sex without condoms or en- gage in barebacking.
