ABSTRACT
This chapter focuses on 'serosorting', which involves seeking out sexual partners of like HIV status to minimize the risks of penetrative sex, including sex that dispenses with condoms. It considers how digital infrastructures of online cruising began to consolidate the practice within gay men's sexual repertoires at the turn of the millennium, and how these sexual infrastructures began to shape relations between users and their bodies in material ways to create new problems and possibilities for HIV prevention. Online cruising sites lend themselves to particular practices of sexual socializing and casual partnering which bear the potential to inform general repertoires of HIV prevention in sexual contexts. The chapter explains how the new interfaces of digital sex began to mediate investments in HIV disclosure as a prelude to sexual sociability. A particular focus of the enquiry was HIV-negative men's feelings and perceptions of presence of HIV-positive individuals in sexual environments they shared with them.
