Because of the insistence of virginity before marriage, the custom used to be that new husbands would show off the bloodied sheets to family and friends after the couples’ wedding night to prove his wife was a virgin. But because a hymen can break from several different reasons women who feared they might not bleed would gouge their thighs with their nails so they would bloody the sheets and not be shunned or killed. Scary
horrifying indeed. the question is, where does this systematic oppression of women in almost every religion come from? those writers of the “holy” scriptures must have been somewhat insecure and weak characters, that they feared their women would seek sexual pleasures elsewhere. so they invented ridiculous laws justified by their fictional gods to keep the control in spite of their sexual impotence.
conclusion: the basis for religion are limp-dicked prophets!
(hahaha, sorry, not really a scientific analysis)
