I've been dating my gf for about a year and a half. shes now 19 turning 20 soon and im 22. I havent had much sexual experience before we started dating but I had some, she did not. I took her virginity over a year ago and everytime we attempt sex it hurts just as bad as the 1st time. The pain is so bad for her that she rarely ever agrees to have sex with me and when we do she asks me to hurry up and finish. We can only do it in one position, she wont let me enter any other way. We have to have sex with her on top and I have to do all the work, while she basically clamps her teeth together and prays for it to be over.. My gf is a smaller person, around 5'4 and normal weight for a girl her size, im around 5'9 and normal weight. I defnitly think her body size has something to do with it, but I think there probably much more. On top of this, my gf seems to be one of those people who are just not interested in sex, she never initiates it, although i understand why, she never masterbubates not even while growing up. The only thing she enjoys is having me rub her area or me give her oral, but no insertion at all. I bought her a very slender sex toy and she never uses it unless i help her with it and she says she gets no enjoyment out of it. Me on the otherhand, I have an extremely high sex drive, I masterbate at least 2-3 times dailey, I watch porn. I'd be on top of my gf all the time if she would let me. The only thing we do regularaly that gets me through is she gives me oral. But im going crazy I need sex, I'm afraid if we can't rectify this situation im going to try to find sex somewhere else, these thoughts are occuring frequently lately, and its scary since this kind of behaviour is not in my nature. I'm hoping someone can give me some insight on how to change things around. It would be GREATLY appreciated!
