I just started dating this guy and we've tried to have sex twice. I say tried because it front happen, we'd fool around and give each other oral but when it got down to it nada. He says he can't fit because I'm too tight and hes not the most well endowed guy around, which I don't care about. Is it possible to be too tight to have sex? I'm dying over here, any tips to "loosen" a girl up?
