Sex education should be carried out by parents together, and both parents should participate. In adolescent boys, the roles of father and mother are different, but they are both very important people in their children's lives and have an important influence on their development.

Dad is usually regarded as a person who pays more attention to practice and skills, while mom pays more attention to emotions and interpersonal relationships. Therefore, in sex education, fathers can teach their children some knowledge about physiology and safety measures, and at the same time, they can encourage their children to participate in some sports and social activities to improve their self-confidence and social skills.

Mothers can pay more attention to their children's emotional and mental health, convey correct values and outlook on life to their children, and help them establish healthy sexual concepts and emotional cognition. In addition, mothers can also discuss some gender, physical and emotional issues with their children, so that children can feel understanding and support.

In short, sex education needs the joint participation of parents, and both parents can give full play to their respective advantages and provide children with comprehensive, scientific and reasonable sex education.
