LG is it possible for a guy's erection to be so hard it hurts your female partner whilst having sex.
Dear Vespar,
It is not the erection itself that "hurts your female partner'' - it's the propulsion with which you force the rock hard object into the vaginal cavity. If she is not sufficiently lubricated, then it's going to hurt having something go in and out with some pressure and force. If you just take it very slow and make sure you excite her so that she will lubricate naturally (use extra waterbased lube if you are wearing a condom), then her vagina will expand naturally and make room for the penile propulsion.
Walk softly when you carry that big stick,

Another possibility is that if you were in a position where you were penetrating her deeply you may have been bumping into her cervix, this can also cause pain.
Yes indeed! This is the reason why I hate it when I discover that a guy took vitamin V when he doesn't really need it. The viagra turns a normal erection into something that feels like a baseball bat. Even fully erect, a cock is still pliable enough to shape to the vaginal cavity. When an erection is 'too' hard, as happens when viagra is added unnecessarily, there is no pliability at all, and it feels more like being battered rather than having a nice fun filled romp.
Now I wish they would come back again, with a fervor to match my undiminished desire! But, hey, at least I don't hurt anybody's vagina! Hobbit Giorgio
They still happen to me, when I wake up if the erection prevention nerve center at the base of my spine has fallen asleep. It's quite hard, but not very sensitive when that happens. That could explain why ED treatment may not speed orgasm.
