I had sex education in primary school. About grade six or seven. I think perhaps children are too immature to deal with it at that age. But with the age of puberty getting younger and younger, children should be learning about sexual health and awareness at a younger age. High school is too late for some kids. By then a lot of the kids would have already experienced erections, periods, and perhaps even some sort of mild sexual interaction with others. If the government is going to control our school system, they should at least do it properly and educate our children thoroughly in all fields including sexual health and awareness.
