There was once a news that a parent complained that the school teacher was educating his 9-year-old daughter about sex. At that time, the matter was raging on the internet, but the voices of netizens were roughly divided into two categories. Some people think that schools really shouldn't educate their children like this, while others think that schools should educate 9-year-old girls about sex long ago. Personally, I prefer the second statement. In fact, it is very late to start sex education at the age of 9. Perhaps many parents can't accept their children to learn this knowledge because of traditional ideas, and think that sex education is a bad communication. In fact, this is a completely wrong idea.
The 9-year-old daughter has reached the age of receiving sex education. After receiving sex education, children can better understand the relationship between men and women. Now that children are gradually mature, giving them some sex education can also help them learn how to protect themselves, whether they are boys or girls. Parents who oppose sex education are too pedantic. They don't think such things can be said in public. But only when children learn these things can they learn how to protect themselves from harm.
In the past, many children didn't receive sex education, so they didn't know how to tell their parents after being bullied, or even that it was a kind of injury, so that when they grew up, it became the shadow of their childhood. At this time, many parents regretted it and felt that this should have been taught to their children long ago. In fact, I think when children are in kindergarten, there should be different education for men and women. Don't think children are young and don't teach them this knowledge. Many adults may think this is a very shy thing, but for children, this is just a simple knowledge.
