Does your S/O smack your face during sex?

A few weeks ago my bf very lightly patted my face - it wasn’t a slap/smack because it was so light. I didn’t think too much of it, I figured maybe he went to just touch me but accidentally did it harder than he meant to.

But the other night when we were having sex, he smacked my face. So naturally I retaliated and slapped him in the face and said “don’t hit me”. He apologized and we continued. Afterwards he apologized again and said “I didn’t mean to do it that hard”. Now I’m wondering if I should’ve told him not to do it at all because I’m not okay with it. You can slap my ass or my boobs but leave my face alone.

He’s never slapped my face during sex before and we’ve been together a year and a half. So I wanna nip it in the bud before it gets carried away. Idk if he’s watching face-slapping in porn lately or what but it stops now.

Just wondering if anyone else’s s/o has wanted to slap their face during sex.
