Sex education for young people remains a crucial issue, not only in the fight against sexism and sexual violence but also in providing everyone with the tools for a fulfilling emotional, relational, and sexual life. This issue of *La santé en action* aims to show how sex education today is no longer based solely on risk prevention; rather, it is part of a comprehensive vision of health and well-being. This new, positive approach—guided by UNESCO’s international recommendations—emphasizes learning about one’s relationship with one’s body and intimacy, as well as communicating about emotions, respecting oneself and others, and more. Consequently, a “comprehensive” sex education program—one that is progressive and tailored to all ages—requires a multidisciplinary approach in educational interventions, both in and out of school. This represents a shift for those involved, and they need support as they adapt.
