Does Islamic law include a sexual culture, when should a boy be taught about sexual matters, and what are the limits of this education?

Islam has encouraged every beneficial knowledge and warned against every harmful knowledge, or that whose harm outweighs its benefit. Sex education should not be taught to adolescents absolutely in schools. Rather, it should be taught to those who need it, to the extent of their need, by relatives such as the father and mother, or a trusted teacher, and with Islamic regulations, such as when young people are about to get married, or as part of answering questions related to janabah (major ritual impurity), nocturnal emission, nifas (postnatal bleeding), and menstruation. Spreading this culture in newspapers and on channels incites young people and pushes them towards practical engagement, and has led to an increase in assault and harassment in countries that preceded in spreading it. So, let those who call for this in Muslim countries fear Allah.
