My girlfriend was a virgin when I met her, but we have had sex quite a few times now and it isn't feeling good for her. She can orgasm when I use my fingers or do oral but when we have sex it doesn't feel good for her at all. She says it hurts when I first put it in but then after that she can't feel it. The doctor told her it may have been a lubrication problem so we tried lubrication only to find it did nothing. My penis is 8 inches long and 5 1/2 inches in circumference. I say this because I am wondering if I am too small or too big. I thought that eventually the girl should stretch so that it doesn't hurt but it is still tight when I put it in. I don't know what to do because it is really important to me that it feels good for her. I can't get really excited about sex with her because it doesn't feel good to her. I can't orgasm either because I feel like an idiot being on top of her and having her just lay there and not even breath hard. Other girls I have been with and still talk to claim that sex with me was great, even the bitter ones, so I know it isn't a normal occurance. I am getting really worried that sex will never feel good for her and this is a BIG problem for me. I am wondering if anyone has had this problem and whether anyone can offer any suggestions.
