The aim of this article is to question the reference to homosexuality as a homogeneous block of common historical experience. The text reconstructs dissident sexual sociabilities mediated by the axes of age, gender and class, to explore the diverse erotic-affective experiences during the decades of 1960 and 1970, until the process of emergence of gay sociabilities in the decade of 1980. This study analyzes a documental corpus that includes testimonies, periodical and medical articles, trial records and papers of the Departamento de Inteligencia de la Provincia de Buenos Aires (DIPBA). This material allows for conceptual and methodological reflections on the historical approach to sexualities.
