The present study examines imbrications between performativity and ideology with regards to the (re)production of heteronormative discourses regarding gender and sexualities and to ways of destabilizing, resignifying and subverting such limiting discourses. Our research is guided by a queer position that sees gender and sexuality as identity performances and not natural facts (BUTLER, [1990] 2003, [1993] 2002) and a linguistic perspective that considers narratives to be a way of intervening in the social world in order to change (or reiterate) normalizing and stigmatizing ideological discourses (MOITA LOPES, 2008; THREADGOLD, 2005). It focuses on gender and sexuality identity performances in digital narratives of practitioners of pegging, a sexual practice in which a woman uses a strap-on dildo to penetrate the anus of a man (who identifies as heterosexual). Pegging is frequently the target of discrimination due to the ideological association between men s anal pleasure and homosexuality (SÁEZ e CARRASCOSA, 2011) and that idea that it is a deviant practice related to BDSM (another set of stigmatized practices) and, therefore, supposedly not intimate. In the narratives and interactions that were analyzed, stemming from virtual ethnography (HINE, 2000, 2005) in the online community Pegging 101, three principal topics emerged: (1) the users difficulties in creating a clear separation between what counts as sensual pegging or BDSM, (2) different views of the relationship between pegging and intimacy, including intimacy being created through revealing things about oneself or by practicing role reversal and (3) problems in dealing with the ideological association between male anal pleasure and homosexuality. Although pegging has the potential to be a subversive practice that could contribute to changing heteronormative conceptions of gender and sexuality, in their narratives, most of the community s users tried to resignify pegging as a normal practice, fitting it into ideological heteronormative discourses about romantic love and intimacy and reinforcing the gender binary and hegemonic masculinity. During the resignification process, the community s users usually reiterated certain heteronormative ideological discourses in their attempts to subvert others, in particular, by performing masculinities that valued courage or aggression as a way of proving they re not homosexual, or by reinforcing negative stereotypes about BDSM in their attempt to prove that pegging can be intimate. As such, by studying how heteronormative ideological discourses are performatively (re)produced at the same time as certain destabilizations emerge, this study contributes to understanding how to foster a narrative politics with more discourses that are transgressive and fewer ones that reinforce heteronormativity, creating more ruptures and visibilizing possibilities for alternative discourses about gender and sexuality.
