This article engages with the postfeminist debate on girls’ sexuality in contemporary Italy. The huge popularity among adolescents of social network sites (SNSs), which involve a vast mobilisation of personal images, has given rise to new concerns and a moralising gender panic about girls’ sexuality. Drawing on critical girls’ studies, and based on the outputs of a qualitative research project, the article discusses the gender discourses that emerge from Italian girls’ digital practices on SNSs, with specific reference to girls’ online self-representation through posting and sharing photos on Facebook and other SNSs. The article explores how sexual regulation works among girls in the digital context by analysing the postfeminist norms of female sexual embodiment in contemporary Italian digital culture. In doing so, the article hopes to contribute to the transnational academic debate in media and cultural studies by showing the discursive and visual conditions of possibility which shape girls’ digital sexual subjectivity on social network sites.
