Let children correctly understand the differences between men and women, which will help children get along with the opposite sex better and know when to keep their distance. It also helps children to better protect themselves and know what behavior is an infringement and disrespect to themselves, so as to avoid being harassed by others. Some children have not received the correct sex education, but only vaguely understand the fur from the Internet, but the knowledge on the Internet is mixed, which is very likely to lead children to form a wrong understanding of this.
Moreover, most college students are psychologically and physically mature, which is also the stage when they have the most contact with the opposite sex and are most curious about sex. Without proper sex education, it is likely to do harm to their health. Therefore, systematic and correct sex education is even more important.
