Only this past Saturday I was with my boyfriend and we decided it was the time to take this to the next level. I am/was virgin. It was very difficult to get his penis inside of me, my body would involuntarily take it out. We didn't get anywhere. I felt pain all the time, and even he, who has had sex before, said he felt pain in the tip of his penis. I still feel discomfort down there...

You may simply have a strong hymen. He or both of you need to explore with fingers or other smaller objects and lubricant like KY Jelly. And since you are sore, hold off on the actual intercourse until you are healed and comfortable knowing your body. He can look, but so can you with a mirror and a light.
(He should have known not to just barge right in, so I guess he isn't very experienced for a non-virgin... he needs to study up on foreplay!)

Thank you.
But he is really experienced (stated sexual life at 13, and is 18 right now)
I just want to know why I still feel pain, there has been no follow up to what happened that night, no more sex to be up front
I don't even know if I really lost my virginity
I read online about a problem called vagi-something.
When you close up and won't let it in
I fit some symptoms but the after pain isn't one of them
When I get wet I feel pain too..
Is this like post trauma or something
Should I go see a gyno?
