Virginity is sacred. Mary conceived Jesus while staying a virgin. Whether she had anal sex with the Holy Ghost remains unclear to this day. Muslim men are rewarded with no less than 72 virgins with large breasts in paradise. Jesus himself must have been a virgin until his death since he never married. Of course virginity is also a big deal with teenagers.
Society is cruel: boys try to get laid rather quickly whereas girls are being slutshamed. But since we’re all human and the overwhelming majority of us has sexual urges, it is hard (pun intended) to resist what is going to happen sooner or later anyway. Religions were always good at trying to fight against human nature. The question is: who will win the fight in the end?
