so me and my bf had sex a couple hours after i shaved everything. after the first round it kind of burned when he put it in. i didn’t think it was that bad so throughout the day we did it maybe 3 times. we talked about it at the end of the day and he just said he thought he burned a layer of skin off or something bc we do it rough. but it looks red and irritated around the hole. i don’t wanna worry or anything but it’s the next day and it’s still red and irritated a little. what is it?????
