The college hookup scene is a profoundly gendered and heteronormative sexual field. Yet the party and bar scene that gives rise to hookups also fosters the practice of women kissing other women in public, generally to the enjoyment of male onlookers, and sometimes facilitates threesomes involving same-sex sexual behavior between women. In this article, we argue that the hookup scene serves as an opportunity structure to explore same-sex attractions and, at least for some women, to later verify bisexual, lesbian, or queer sexual identities. Based on quantitative and qualitative data and combining queer theory and identity theory, we offer a new interpretation of women’s same-sex practices in the hookup culture. Our analysis contributes to gender theory by demonstrating the utility of identity theory for understanding how non-normative gender and sexual identities are negotiated within heteronormatively structured fields.
