This article focuses on the experiences of young Tunisian women who identify themselves as lesbians, and it tackles the issues of body appearance related to a marginalized and so-called atypical sexuality. Following a socio-anthropological approach, the study is based on a semi-directive interview with three young women who display their marginalized sexual orientation. Qualitative analysis reveals the power of gender norms in constructing relations with others and the perception of difference. The young interviewed women adopt a transgressive stance of socially recognized norms and claim an identity perceived as out of the ordinary. It is indeed about the identity of "woman" and "lesbian". In this sense, their logics of action wish to encourage a change of outlook on the canonical model of femininity, or even the acceptance of different types of women.
