Is there something wrong with my girlfriend? She was a virgin but when we try to have sex, it wont go in all the way. She doesn't feel any pain when I first insert it in, and it goes in about 5 inches and then it seems like there's a wall type of thing blocking it from going any deeper. It's not because she's not aroused she even orgasms. But it just wont go in all the way. Is there something physically wrong with her?
Have a nice day,
Brad


Most likely has something to do with position and relaxation. The more she relaxes, for instance right after her orgasm, the less likely this is. We all have some positiions that do not quite work right. Try something different.
This is also the reson that all women should have a complete gyn exam BEFORE becoming sexually active. It is unlikely that there is anything "wrong" but if she had had an internal exam you would know whether or not to be concerned.
