Sex education is very important for children's growth and development. Sex education is not only physical education, but also shaping children's moral concepts and values. It can help children to establish a correct sexual concept, improve the level of sexual knowledge, enhance self-protection awareness, and prevent bad behavior and sexually transmitted diseases.

First of all, sex education helps children understand sex correctly. Through sex education, let children know the basic knowledge of sex such as reproductive system and fertility. This helps children understand and accept their own bodies and reduce confusion and misunderstanding about sex.

Secondly, sex education helps children to cultivate correct moral concepts and values. Sex education can help children understand the moral norms of sexual behavior, clarify the legality and illegality of sexual behavior, and cultivate children's sense of self-discipline and responsibility.

Thirdly, sex education helps children to enhance their awareness of self-protection. Children need to know the harm and prevention of sexually transmitted diseases, and how to protect themselves from sexual assault and sexual violence.

Finally, sex education helps children to establish good interpersonal relationships.
