My fiancé and I met when we were 16. We have been together for six years now and are about to get married. This past year, we would try to have sex, and he woulod go limp after a while in the middle. Now its "everytime" we have sex he goes limp. And I try to do things to help him but it's becoming very frustrating because I feel like maybe he's not satified with me anymore and worried because if its like this before we get married, what will it be like after. Is he bored? Not attracted to me? Or maybe even cheating? I don't know but need help. I ask him what's wrong he says he doesn't know. He has even recently cried about it because it frustrates us both.
