Children don't understand sexual knowledge in junior high school, and they don't feel anything when they see their parents making out. They just think it's a bit uncivilized and laughing. Is this normal? Laughing means that he is a normal person.

If you find this kind of scene, he is dull and expressionless, which is abnormal.

Adults should try to avoid opening their children when they are engaged in husband-wife relationship.

One is to sleep in separate rooms, each with a switch device such as "touch lock". Don't let children see these things of adults in the future.

For children in junior and senior high schools, parents should give their children some knowledge about X in due course: there are differences between men and women. Don't invade other people's sensitive parts at will, don't go home with others at will, and so on. Boys are taught by their fathers and girls are guided by their mothers.

It is also a cognitive defect that children don't understand this knowledge at all.

It is better to guide in time.
