I think sex education has nothing to do with age. Although most people can learn with the help of some Japanese teachers' educational videos, there are also some good children who won't go to see those things or even listen to their mothers at all. They are ashamed of their sexual behavior and even embarrassed to entertain themselves. Just like a bunch of couples in Shanghai, they lived together for a long time without getting pregnant. Finally, they went to the hospital for examination and found that the girl was still a virgin, as if she could get pregnant as long as she slept together.

If we really want to have a consistent sex education system, it must be that sex education in primary and secondary schools mainly focuses on understanding sex organs and preventing infringement. For example, one-time educational materials are too exposed and are unanimously resisted by parents. In fact, it really took relevant scholars several years to compile it, but it was rejected just because it mentioned the scientific name of the sexual organ. The thing between my legs is the most terrible devil, and I can't even mention my name.

As the saying goes, "the best time to plant trees is ten years ago, and then now", so we really need sex education. According to those experts, in fact, primary school students are curious about those sex things. If parents don't have a certain degree, they will go to see Japanese teachers themselves. And there is news that a man and his girlfriend feel that they haven't had the inferiority complex in Japanese movies for a long time, so initial education is very important.

And college education, in fact, how to operate, what is sex, they have long understood, just the unlocking of body position, so just like a love rule recently introduced by a university, if you can't live together, you should take good measures, mainly to prevent abortion and promiscuity.
