Because sex is not just an independent single object, but a product of sexual psychology, sexual physiology and sexual emotion that people must understand in the process of growing up, proper sex education for children will help them understand this society, personal physical development and psychological changes, and accept themselves better.

Correct sex education can help people to establish a harmonious marriage relationship and a scientific and civilized sex life, so that children can know how to respect themselves and everyone in society during their growth and development, and their future marriage life will be happier, so that there will be no more social behaviors such as marital infidelity and sexual assault mentioned in the news.

Because children don't have a correct understanding of their bodies, when girls' breasts begin to develop and even come to menstruation, they will feel very scared. At this time, it is necessary to correctly guide children to understand their own bodies and let them know that these are necessary in the process of growth, which is more beneficial to their physical and mental health.
