This study aimed at learning institutional discourses on the sexuality and self-care youngsters. Participants were between 15 and 19 years of age, men and women from public, private, and university educational institutions from the city of Antofagasta in northern Chile. A qualitative methodology was used and 24 subjects were interviewed in-depth. The main findings suggest a flexible relation of young subjects with institutional regulations, either ascribing to their mandates or exercising dissent. Poor implementation of sexual education programs was detected, thus becoming a problem throughout private and public institutions, although with greater social impact on the latter.
