Bareback is a term used to denominate Unprotected Anal Intercourse among men; this practice has gained relevance over the last few decades, some authors linking it to Internet use. The objective of this paper was to identify the main attributes associated to the “bareback” phenomenon and its practitioners, through online interviews carried out with chat users in Mexico City. The interviews covered topics such as hivinformation, bareback knowledge, and the attributes and expectations among its practitioners; the possible motives of engaging in unprotected sex, and the influence thereof in relation to condom use. The results show imprecise information in some of the technical aspects of HIV, positive and negative opinions on “bareback,” motivations linked to the dominant masculinity model, as well as the idealization of gay relationships.
