Thank you! One of the reasons that anal sex is disdained for men is because it involves penetration — which essentially makes you a woman. This kind of thinking was going on back at the time of the Greeks who frequently just fucked between the thighs of the young men they were “having sex with” because it was shameful otherwise to put yourself in that position — of a woman. I think the reason that it’s so scorned for women comes out of the fact that it is not for procreation — it’s for pleasure and not the type that is demure and ladylike.
