In 2021, one of this paper's authors conducted research to obtain a master's degree, while the other two worked as supervisors. The thesis aimed to explore the visions of pre-service biology teachers and teacher educators regarding sex education and gender diversities, recognising the relationship between those subjects and their possible tensions. In the thesis production cycle, there was an attempt to decolonise sex education in pre-service teacher education, a process of decolonising the context of academic supervision happened too. This paper illustrates the research process' particularities, especially how queering ["enfletando"] the supervision process incorporated decolonial cracks through "fleta" reflexivity.
