Hi, I've been with my boyfriend for almost 3years and both 18. We have regular sex, and before I have not had a problem like this. Lately during girl on top position if I grind against him it has started to hurt his penis after a few minutes, this hasn't happened before and we don't know why it has started happening now.
It's really annoying as its one of the only ways I can orgasm during sex and its making sex less enjoyable for us knowing I can't orgasm without hurting him. Anyone had this problem? Or any ideas on what could be causing this or how to help it?
Thanks

He needs to see his doctor about it.

Since this hasn't always happened, he needs to see a doctor, to see if there is a problem.

One thing I feel I should ask...

Do you have IUD? I had a friend who had gotten an IUD and it was somehow placed improper and the tip of it was actually poking the tip of her boyfriends 'member' to the point where he didn't want to sleep with her at all. She ended up having it removed then a new one put in and the problem went away. Though if you do or if you don't he should still get checked out

I will start by saying definitely see a doctor. I'm not debating that at ALL. PLEASE see a doctor.

However, another possibility, is you may have a shallow vagina, which many girls have. And the on top position makes a man go MUCH deeper than any of the other positions. If you are too shallow for him to go all the way through, it could be... mmm... the best way to describe it would be 'bending' his penis. But that's not exactly accurate. But do you get what I'm saying?

I had this problem once with a lover, but I'm not shallow, I'm fairly deep. But he was very large. (a good 9 inches, and I kid you not. But the penis was very SKINNY, and I hated that ;) )
And me being on top, while it didn't affect me, was in a sense squishing and bending his penis. And made it very painfull for him.


Definitely see your doctor. Good luck hon.

And until further notice, either Don't have sex(which I recomend) or if you MUST, don't do that position any more!

I can back this up with personal testimony. My ex girlfriend had an IUD and the 'wire' would poke me when I'd go in deep. I think this could be a possibility of what's going on with you and your guy.
