hey, im 23 but im really inexperienced . its really embarrassing which is why i never want to do anything. my gf is leaving me because of our sex life, and i don't blame her. but i need help for the next time. so...everytime she tried to finger me, just one finger, it hurt so bad! every. single. time. i dont understand. she told me the first few times would hurt but it should get better but it never did. she tried 5 times. it felt like a knife was being shoved in there. and she was going so gentle. is something wrong with me? i made her stop after like 10 seconds of it because it hurt.
There are alot of women with your problem, its not an infection but a medical problem. MTV had a whole show about it called true life: I can't have sex, where women like you feel pain when they are having sex. This has nothing to do with you being nervous or tense. I'm not a doctor or anything but the link below should help you understand. http://www.mtv.com/videos/true-life-i-cant-have-sex/1653589/playlist.jhtml
I would definitely talk to a dr about it. I know its embarassing but it's important. Sex is very emotional and is good for not only relationships but for yourself!
Another option is that your hymen might be too thick. My sister had to have hers surgically removed. Actually there are so many things that might cause this. Definitely talk to your doctor. Do you masturbate? Can you do it without pain? Maybe you don't know your body enough to be able to tell someone else what you need?
