Sex education is self-taught. This is the view held by some teachers. Their reason is that students will still be afraid if they don't talk. If they talk about it in detail and thoroughly, students will try to do it. It's like a small earthquake monitored by a seismic station. If it is predicted, people will be worried. If you don't predict, the house will be crooked.

This view that students will try desperately in sex education reflects the bias of sex education in middle schools-the separation of sex education and moral education. In fact, if students only know some functional structures of sexual physiology and don't understand the significance of social ethics and self-control, they are more likely to do things that they think are interesting and exciting. Sex education without moral education can only lead to sexual ignorance, but can not cultivate students' scientific concept of sex.
