I'm having a problem right now and want to know if any of the other guys here can give me any insight. My bf's pretty hung. He's 8.5 x 5. He and I have been seeing each other for about two months. He doesn't like being fucked and I love it, so we most always end up with him fucking me. I'm experiencing a problem that I've never had before. I am usually rock hard whenever he first penetrates me. But almost immediately after he has his cock fully inside me and begins to fuck me, I begin to lose my erection. It never gets completely flaccid, but it's definitely not hard either. I would love to be able to maintain my erection so that I can masturbate myself while he's fucking me. The sex is intense and I really get off on the way he fucks me. But I'd love to be able to stay hard so that we could cum together. I'm really not able to acheive an erection for some time after he's been inside me. So far we've managed this by making sure I get there first. But I have a problem with that because it lessens the intensity of what I feel when he's pounding my ass. Anyone else have this problem?
