My son is 15. I am a single mother. How can I teach him about adolescence?

This is very difficult, but if there is a necessary process, it is suggested that he can be encouraged to make friends with boys who are well educated at home, so that they may have a general screening and judgment on some things themselves, or they can buy some related books, not books that sell pure sex education, but books that are orthodox and have relevant plots and can learn knowledge. Most importantly, if the child asks relevant questions, don't avoid them. To give children a reasonable, artistic and positive explanation and answer, today's children are particularly smart, accept new things quickly, and adolescence will pass quickly, so don't worry too much. The most important thing is to pay attention to what kind of friends he has made, and don't let his friends lead him astray.
