This doctoral research aimed to investigate, through netnographic incursions (Kozinets, 2010), how pornoculture (ATTIMONELLI & VICENZO, 2017) is constituted in the autopornographic practice in digital social networks, taking communities on Twitter as empirical objects of analysis. Our specific objectives are to describe the interaction dynamics and relationships established in these virtual communities; to analyze the practices of embodiment and performance represented in self-pornographic productions on Twitter, in order to understand what kind of discursiveness is produced about the body, desire and sexual practices by the social actors of these communities; describe the attitudes expressed by these actors with regard to pornographic consumption, identifying their patterns, contingencies and the relationships established with the monetized mediation platforms of self-pornographic practices; finally, to identify modes of capture of self-pornographic practices by the sex market, as well as the operationality of algorithmic surveillance carried out by Twitter and other websites and digital communication devices on the studied communities. Pornoculture and the mediatization of sexuality, in a pharmacopornographic and psychopolitical economic context (HAN, 2018), have reconfigured the way we relate sexually, opening up countless possibilities for enhancing the sexual experience, whether through community connection, use of collective intelligence to occupy urban spaces, virtualization of the body or even the new possibilities of achieving self-pleasure. At the same time, they established new frontiers between public and private, reinforced old sexual and gender stereotypes and promoted new ways of capturing sexual subjectivity through consumption.
