This question is more towards the females of this board, but perhaps men who know the answers also..
I've been with my girlfriend for about 6months now (Im 19, she's 18) and we've been sexually active for some time now. Anyways, 2 nights ago was the first time where she really felt like she had to scream her lungs off. Great! I thought, unfortunately she made me stop, because her parents were in the room next over lol (btw this was done with just oral / hands). Last night we had some more privacy, and I did the same thing. Did what I did before, alot of teasing, etc. When she got to that point again, she tells me she doesn't know whether it feels good or if it hurts. She said it kind of felt like a shock, but still is not sure. Are really intense female orgasm's like this? I tried telling her to relax, but she said she couldn't. I asked her whether she thinks it feels good or not, but she said she is incapable of thinking when its happening

Anyways, I'm kind of nervous because she made me stop again, and I was wondering if there could be anything wrong? This is primarily clitoris stimulation, perhaps soreness or something? Dunno, maybe theres something else. Should she see a doctor? Or am I just being paranoid. Although I must say I am quite proud of myself (got all the sex tips from the board haha, thanks guys!!) Any and all comments helping would be greatly appreciated. thanks guys!
