Breaking Binaries: Gender Non-Conforming Lesbians And The Undercurrent Of Biopower On Dating Apps, Lily M. Connolly Mar 2025

Breaking Binaries: Gender Non-Conforming Lesbians And The Undercurrent Of Biopower On Dating Apps, Lily M. Connolly

USF Tampa Graduate Theses and Dissertations

This study examines how gender nonconforming lesbians experience and navigate algorithmic constraints, commodification, and self-expression on dating apps. Drawing on Michel Foucault’s concept of biopower, this study analyzes focus group discussions to argue that dating apps encode and enforce traditional gender norms. However, rather than acting solely as sites of constraint, dating apps also provide spaces where gender nonconforming lesbians creatively resist these limitations and subvert platform design to assert their politicized queer identities. This research highlights how biopower operates within digital dating platforms while also illuminating the subversive strategies users employ to reclaim agency. By situating gender nonconforming lesbian …
