The sex education we are talking about is actually called "comprehensive education", which is a concept of sex education advocated by the United Nations and implemented by many countries in the world.
The focus of sex education is to cultivate social and sexual relations of mutual respect, help children and adolescents learn to think about how their choices affect their own and others' well-being, and know how to safeguard their rights and interests all their lives.
In the context of China people, when talking about the word "sex", most people may think of reproductive organs first. There are quite a few misunderstandings about sex education. This can't blame everyone for thinking wrong, because there is no education and no communication.
Family sex education is very important because children grow up in the family as soon as they are born. Parents are the first responsible person for children's socialization, and parents should be responsible for their children's custody, so that their children's health and life can be in a safe environment. Therefore, parents should of course carry out relevant education, which will definitely involve the content of education.
This is inevitable for parents. If they avoid it, they are actually not fulfilling their responsibilities as guardians. I think they can rise to this level.
