Due to the taboo found when addressing sex education as a strategy to prevent sexual abuse, it is relevant to understand what children, adolescents and guardians know and think about this subject. In this sense, this dissertation aimed to identify and analyze meanings attributed by families assisted in the Talents of Tatami project, in Petrópolis, about the sexual education of children and adolescents. In addition, identify whether and how sexual abuse prevention campaigns affect children, adolescents and family members; to analyze resistance to the theme of sexual education in the spaces of socialization of children and adolescents and to verify the existence of dialogue within the family about the protection of the body as a form of care. From a qualitative approach, the research adopted as an instrument for data production the realization of semi-structured interviews with children, adolescents and guardians inserted in the Project Talents of Tatami. For the analysis of the empirical material produced, the method of interpretation of assigned meanings was used. The results revealed that, despite the taboo that persists around the theme, children, adolescents and guardians are interested in knowing more about sex education, as well as the presence of women as main responsible for information on body care. Data analysis allowed us to know several forms of care to which families attribute the meaning of actions to prevent sexual abuse, giving them importance.
