There's quite a few accounts on here that will argue in good faith and bad faith that people enjoying oral, anal, gay, bi, or any kink has already ruined society, whether it's solely via porn or real life.

The argument usually starts with an assumption that nobody did those things before and it's obvious that life was better before for everyone when those things were viewed as shameful.

Personally I think it's been known for centuries that sex is a pleasurable activity and controlling pleasure is a good way to control people.
