"The sooner the better" is a very ambiguous and rude expression. Are you preaching how to use condoms as soon as possible? Or teach you how to know that the sooner your body changes, the better? This question itself is very rough, which is also a very common phenomenon (because when we talk about sex education, we think that "children should not understand" in traditional culture, so when answering this question, we need to insist on one word: moderate age.

What is school age? Teaching the corresponding knowledge and attitude at the corresponding age is a complete education system, just like learning pinyin in the first grade of primary school and writing argumentative essays in high school Chinese class. There are different contents and methods for different age groups.

On the question of sex education, first of all, I recommend the 20 18 version of the Technical Outline for International Education Guidance compiled by UNESCO (the revised Chinese version has been released after the release of this answer). If Chinese version is needed, please refer to version 20 10.

In the guidance of version 20 18, the appropriate age for receiving sex education is divided into 5-8 years (middle childhood), 9- 12 years (later childhood), 12- 15 years (adolescence) and15-. Years old (adolescence).

The learning goals of different age groups are set reasonably in stages.

For learners of different ages, the knowledge they receive should match their cognitive ability, and people with mental retardation and learning disabilities should be included in the learning system.
