my girl friend says it hurts

Assuming that your girlfriend is about the same age as you the answer might simply be she isn’t developed enough down there to comfortably fit a penis. There are a few things you can try though. First on the list is use plenty of lube, if you don’t have lube available you can use saliva. It might seem strange or gross to use spit to lube you or her up but I promise it works very very well. My second suggestion to avoid what she is describing as stomach pain would be to not put your penis all the way into her. What typically happens when girls feel “stomach pain” during sex is the penis is hitting the cervix which is the opening to the uterus. The cervix can be very sensitive and many women find the sensation of a penis hitting it uncomfortable and sometimes even painful. You also might try letting her get on top of you during sex since she can control the depth of penetration and the movement to prevent it from hurting. As far as fingering her goes, you CAN typically reach the cervix with your fingers as long as she isn’t sexually arounsed. If she is very small then it could be possible that you reach her cervix even when she is aroused in which case you need to listen carefully to her if it becomes unpleasant. I hope this helps you out!

Well, I am seriously hoping your over 18…but that’s beside the point.

Maybe she’s not ready for sex or sexual things and her stomach is telling her what she won’t listen to from her heart.

If it was just during sex, I’d say you might be hitting her uterus with your penis, which can cause discomfort in that area, but unless you have like really really really long fingers, that’s probably not the case.

I agree with gt86fieroguy…your penis might be to big for her or you might be doing it to hard try to ease up on her and try other positions like from the back or her on top
