I really feel like unless it's super gently put in like a game of operation (DON'T TOUCH THE SIDES! "O-PER-A-TION"!), MOST PiV sex is kind of like rape, PiA sex too, that's penis in ass if you didn't know. Idk, something about those penises just...seem rapey to me. I'm glad if I ever want to get some person pregnant and they want to be a birthing person or a person of pregnancy, we can do it nice and safely with a turkey baster, no chance for anyone losing control of their bowls that way, sex is far too vigorous when it's enough to cause an orgasm, far too dangerous /vent
