The construction of gender is deeply related to socio-historical and cultural expectations. From birth, human beings are immersed in a cultural context endowed with signs and meanings that represent the symbolically feminine or masculine universe. Indirectly, there is a language that repeatedly reinforces typically feminine or masculine patterns. However, this discourse implies the exclusion of different modes of existence that do not feel represented in the binarism often present in our language. Taking this reality into account, it is necessary to co-construct a discourse that is inclusive and encompasses the different forms of human existence, especially in the inclusion of trans [People who do not recognize themselves in the gender they have been assigned, taking into account their genital characteristics, and wish to assume a gender other than the one they have been assigned (Porto et al., ReAD – Revista Acadêmica de Divulgação Científica, 1(2), 13–16, 2023)] people. This article therefore draws on cultural psychology and queer studies to analyze the process of gender construction in order to question binarism and cisheteronormativity [According to Costa et al. (Mosaico: Estudos em Psicologia, 11(1), 65–82, 2023) “Cisheteronormativity is the naturalization and normalization of a specific way of relating emotionally and sexually: a cisgender man relating to a cisgender woman, assuming a linearity between the somatic body, sexual practice and gender identity, a linearity that maintains the masculine x feminine binary.” (p. 67)]. Cultural practices around gender and sexuality are complex and shaped by diverse socio-cultural contexts, which need to be re-signified and reconstructed from an inclusive narrative. The research emphasizes the importance of social institutions such as the family and school in breaking down normative discourses about gender and sexuality. The importance of discussing gender and promoting public policies lies in contributing to the construction of a society whose values are grounded in gender and sexuality diversity, breaking away from the binary and cisheteronormative perspective.
