This article proposes a debate on gender identity issues, with a main focus on masculinity in the 21st century. Moving towards a perspective that is not limited to sexuality, the concept of hegemonic masculinity is explored, influenced by several theoretical fields, such as cultural, sociological and psychoanalytic studies. The methodology adopted involves writing about oneself and remembering personal experiences, highlighting the importance of this reflection on subjectivities in the training of future teachers. The results and discussions address the influence of patriarchy and the historical construction of masculinity, as well as its hegemonic manifestations in various social contexts, such as education, work and health. It is concluded that hegemonic masculinity perpetuates male domination over women and non-normative men, but its definition and practice are complex and varied, and it is important to consider individual and contextual particularities in the analysis of male identities.
