Sex education refers to an educational activity that helps children, teenagers and adults understand sex and sexual behavior and promote their self-awareness and sexual health through scientific, systematic and appropriate methods. The purpose of sex education is to help people develop healthily, enhance self-protection awareness, prevent sexually transmitted diseases and adverse consequences, and improve the level of social civilization.

Starting sex education in kindergarten may cause controversy. Some people think that kindergarten is an important stage for children to receive education, and should pay attention to enlightenment education and basic knowledge, not sex education. They think that doing so may arouse the resentment of parents and affect the effect of education.

However, it has also been suggested that sex education for children is very necessary. Starting from kindergarten, sex education can help children understand basic knowledge such as body structure, gender differences and gender roles, cultivate healthy sexual concepts and improve self-protection awareness. At the same time, offering sex education courses in kindergartens can also promote communication between parents and children, so that parents can better understand their children's thoughts and needs and help their children grow up better.

Therefore, whether to carry out sex education in kindergartens needs to be decided according to specific conditions, including education level, cultural literacy, family background and other factors. Whenever sex education is conducted, children's developmental characteristics and psychological age should be respected, and appropriate ways and means should be adopted to continuously improve the quality and effect of sex education.
