Sex hurts alot ? Help?

It sounds like he's hitting your cervix.

The average vaginal canal is 3-4 inches long, increasing to 5-6 inches when aroused and 'tented' - so unless he has a very small penis then it is completely possible for him to be hitting your cervix, especially if you're not fully aroused. Your cervix also moves about, closer to ovulation it lifts up but most of your menstrual cycle it sits lower down and especially so close to menstruation, and it will also move about so sometimes sit further back - thus some days it would be more likely to get hit.

Make sure you're fully aroused prior to penetration - remember that being 'wet' is only the first stage of your vagina getting ready for penetration, ideally engage in foreplay until you climax at least once to ensure your vagina has increased in size and tented - this will help reduce chance of hitting your cervix as well as reduce any chance of pain in any other way from intercourse. If it's still a problem when fully aroused make sure he is gentle, opt for positions with shallow vaginal penetration (e.g. Elephant) or positions where you have more control over the depth of penetration (e.g. girl-on-top).

There's no such thing as 'Virginisum' but I assume you mean Vaginismus which is when vaginal muscles contract and spasm during vaginal penetration - this is not what you're experiencing. With Vaginismus it is painful and difficult, if not impossible, for the penis to even enter the vagina because it is the muscles within the first few inches of the vaginal canal that spasm so the penis cannot enter.

He very well could be hitting ur uterus... its been 7yrs since i was a virgin and that happens to me at certian times in my cycle. Try different positions u learn what ur body can and cant handle, if ur not wet enough it will hurt, take it easy in sex especially when he first sticks it in lol i hope this helps:)
