Okay ladies. I need some free advice here.
My boyfriend and I recently started having sex about 3 weeks ago. He's pretty well-endowed and I'm kind of tiny...(5'8, 138lbs)..and well here's the thing: When we have sex...it hurts like..inside of me. It feels like he's hitting something up in there and I can't really tell what he's hitting unless it's my cervix? I've never been with a guy thats well endowed before. The last guy I was with was never a problem. We had sex and everything was fine...but with my boyfriend now, it just hurts (but only if he goes in too far). It's kind of a dull aching pain too. Like..a cramp in a way. I really don't know how else to explain it. It's pretty much unbearable though..I can tell you that much. It's like losing my virginity all over again. Bleh. Anyway..if he fingers me, I don't get that kind of pain at all (I'm guessing because his fingers aren't as long as his penis *DUH* so therefore his fingers aren't hitting something they arent supposed to)..but hmm...Have any of you had a similar problem?? We've only tried the missionary position...I've been to a gynecologist...had a pap smear, everything turned out fine..--he said my cervix looks healthy and so on and so forth. What could he be hitting and is there a way for him to maybe bypass that or is he just going to have to not fully penetrate?
Sorry this was so long.

Advice/Help PLEASEEEE!! It would be greatly appreciated.
God bless.
