Abstract
This paper aims at analyzing the main findings of a research on sex-affective experiences of cis heterosexual adult men from the cities of Montevideo and Maldonado in Uruguay. In the approach of their discourses from an ethnographic perspective, we see that their experiences and subjectivities are traversed by the mandate of compulsive heterosexuality that, even if it is not actively subscribed, it appears as a permanent background that configures their masculine identities. Furthermore, it acquires different discursive characteristics according to the social sector to which the individuals belong to. It is observed that in men’s sex-affective trajectories, they assign different meanings to their ties with women, moving between the affective, sexual and rational dimensions. This "three-dimensionality" is configured according to their vital projects and the place men assign to certain female identities
