Parents should pay attention to the following aspects when providing proper healthy sex education to their children: 1. The right age From a psychological point of view, the best starting period for receiving sexual health education is at the age of 5. The gender differences between men and women, especially the differences in the first sexual characteristics, are best answered before the age of 5. Sex education should be relatively advanced, but not out of the child’s ability to understand. 2. Appropriate method Before the child is 5 years old, you can use the parents’ body to talk, but after 5 years old, it is more appropriate to use books, audio and video materials and other methods. 3. Appropriate content Sex education for children should not be simply understood as sex knowledge education, but sex education involves many aspects such as physical, psychological, social, moral and ethical. The content of each age group should be focused, and simple issues such as gender knowledge should be addressed before the age of 5. Before puberty, education on sexual physiology should be given; when puberty develops, education on sexual psychology and sexual morality should be given. In short, sex education for children should be calm, frank and natural. When children ask questions about sex should not be evasive, after all, children are still immature, the answer can be simpler, the key is not to cause psychological pressure on children, so as not to lead to abnormal sexual mystery and abnormal shyness.
