The purpose of this paper is to study the relationship that exists between training and the definition of identities (individual and collective) and the development of a democratic citizenship, which is taken as an example of the analysis of sexual and gender identities.The article aims to demonstrate that for a democratization of these identities one must leave behind the dichotomous conception that characterizes them and instead deploy a consideration of them as accessible, fluid realities for all democratic citizenship in which the theoretical contributions provided by transgenderism may be useful to think more inclusively about our lives.
