My boyfriend and I were both virgins a few months ago and we went all the way. He’s been orgasming every time, for me it’s like once every four times. I’ve asked if he can tell when I do and he says no and he doesn’t know that it’s been so little. He also doesn’t know that it’s been hurting when we do it (it feels like cramps but just when he tries to put “it” in all the way). How do I explain this stuff to him without seeming like a bitch and without embarrassing the both of us?
