RESUMO
Background: The need to educate adolescents about healthy sexual behavior motivated the development of an education program on sexuality. Aim: To describe the knowledge of students about sexuality and the implementation of a sexual education project. Material and Methods: Sixty students aged 14 years (34 females), attending the third year of secondary education participated in dynamic workshops about healthy sexual behaviors. Results: The most common reactions of students when facing situations related to sexual behavior were shame, anxiety, fear and lack of knowledge. Group dynamics improved the practical knowledge of students about sexual behavior, allowing them to make informed decisions. Conclusions: These innovative educational techniques should be expanded to other students.
