I don't like sex education in schools cause they make it sound like zina is OK or homosexuality is OK, and so on However, the Muslims obviously need to educate their children with regards to sex, do they not? Children need to learn when ghusl is performed, that masturbation is haram, that a spouse has a right to satisfaction, etc etc etc Most of that can just be done by giving them a book, like the one done by Mufti Ibn Adam
