So my boyfriend and I have been together for about 3 months. I can honestly say he's the best I've ever had. However I've noticed that I have period- level cramping after we have sex. Usually when he goes really deep. I don't believe he's hitting my cervix (and he says he doesn't think he is). But it's really uncomfortable.

Has anyone ever had this issue before? Has anything worked for preventing pain?

I guess I should mention I'm 25 and he is 26.
