So, my boyfriend's penis always tilts to the left, and this becomes very pronounced when he has an erection. Usually I don't have pain when we have sex, but sometimes it really does hurt and it feels like he's stabbing me because im feeling his penis all the way on one side. We've tried cow girl and doggie style besides missionary, me doing all the work and him not moving, plus a few I think we made up, but whenever it begins to hurt nine times out of ten our sex is over. It's starting to become a problem and I've actually cried just because it makes us stop having sex- it's really frustrating. The main problem is he always tilts, but it doesn't always hurt, so many times I've never even noticed it, so I can't really understand why it hurts to have sex with him sometimes, and not others. If you know any thing that might help if really appreciate it, thanks
