First of all, parents, as their children's first teachers, should not avoid this problem. They should educate their children about the differences between men and women from an early age. Even kindergarten children should know that girls should go to the ladies' room, boys should go to the men's room, and boys should try not to go to the ladies' room or the ladies' room with their mothers. Children will ask some questions about sex out of curiosity (such as how I came), and parents should answer them with a scientific attitude. It is forbidden to use dirty words to influence children's understanding of sex.
Furthermore, in terms of children's sex education, we should give correct guidance: protect ourselves. In recent years, many news about children being molested have emerged one after another. Why? Because of the lack of consciousness to protect themselves. Some children's understanding of sex comes entirely from vulgar and unhealthy adult movies, and unhealthy sex gives them wrong guidance, so we should give them correct guidance before this, and parents' sex education should complement the school teachers.
