ABSTRACT This study adopts a Critical Femininities approach to examine the under-theorised domain of sexual norms on dating apps, with a focus on the self-representations of Spanish heterosexual women on Tinder. Through an analysis of three hundred profiles, this research investigates the gendered dynamics influencing these women’s portrayals of themselves in the digital dating context. Combining quantitative and qualitative methodologies, the findings reveal patterns in women’s online-mediated intimacies and sexual subjectivities, highlighting the pervasive influence of femmephobia in this space. Empirical data underscore how these dynamics operate, providing insight into the extent to which hegemonic gender beliefs and regulatory norms shape digital femininities. Moreover, a discursive examination of the ways these Spanish women construct their gendered and sexual identities on Tinder offers a critical view of the constraints and possibilities they face within this specific socio-cultural framework. This study’s focus on linguistic and representational strategies in digital self-presentation deepens our understanding of how normative gender expectations continue to shape social and sexual interactions in contemporary online spaces. In so doing, this research contributes to broader discussions in Gender Studies and linguistics, illustrating how femininity is performed, policed, and navigated in digital dating environments.
