With the development and progress of society, sex education has become more and more important in our lives. For children's sex education, many people think it is too early to start sex education from kindergarten, but I think this view is wrong. In my opinion, it is very necessary to start sex education from kindergarten, because it can help children better understand their bodies and gender, and also help them form correct sexual concepts and values. First of all, sex education from kindergarten can help children understand their body and gender. In kindergarten, children began to realize their body and gender and began to be curious about these aspects. If children can be taught correct sexual knowledge at this stage, they can better understand their body and gender, so as to avoid inappropriate behavior because of their curiosity about these aspects. In addition, kindergarten children are curious and easy to accept new knowledge, so it is easier to receive sex education at this stage. Secondly, sex education from kindergarten can help children form correct sexual concepts and values. In modern society, sex has become a very important topic, so we need to educate our children about correct sexual concepts and values. If sex education can be started in kindergarten, then children can better understand sexual problems and form correct sexual concepts and values. In this way, they can better face sexual problems in the process of growing up in the future, so as to avoid making wrong choices because of ignorance of sexual problems. Finally, sex education from kindergarten can also help children prevent sexual assault. Sexual assault has become a very serious problem in modern society, and children are one of the most vulnerable groups. If sex education can be started in kindergarten, then children can better understand their body and gender, so as to avoid becoming victims of sexual assault. In addition, sex education in kindergartens can also help children learn to protect themselves, thus preventing sexual assault. In short, it is very necessary to start sex education from kindergarten. Through sex education, children can better understand their body and gender, form correct sexual concepts and values, and prevent sexual abuse. Therefore, we should start supporting sex education from kindergarten and actively promote this work.
