Parents should pay attention to the following aspects when educating their children correctly: 1. In theory, the gender differences between men and women, especially the primary sexual characteristics, can be answered before the child's puberty. As far as the current social and cultural situation is concerned, it is best to answer the difference of primary sexual characteristics between men and women before the age of 5. Sex education should be more advanced, but it is inseparable from children's understanding ability. 2. Appropriate methods Before the child is 5 years old, he can speak with his parents' bodies, but after 5 years old, it is more appropriate to use books, audio-visual materials and other methods. 3. Appropriate content of children's sex education, the content of each age group should be focused. Simple problems such as gender knowledge should be solved before the age of 5. Before puberty, sexual physiology education should be carried out; When teenagers develop, it is necessary to carry out sexual psychology and sexual morality education. In short, sex education for children should adhere to natural and appropriate principles, and should not be done deliberately, nor should we look at children's problems from an adult's perspective.
