Okay, so this may be a little too much information, sorry in advance.. but i get this really sharp pain underneath my ribs when me and my boyfriend have sex. It ONLY happens when i'm on top, and it's happened every time. I'm not sure what it is, and many people have told me to go to a doctor to get it checked out, but i want some sort of idea of what it might be and if it's serious before i go to the doctors. Just recently it's started hurting a lot worse than in the past to where i'm in tears and can't move at all.
if somebody could help me that'd be great... i want to know what's happening.

Thanks.
