Just back from a working/vacational week in New York, so a little jet-lagged, please bear with me.
Not ok, really, to feel as if it is going anywhere near your stomach, hurting a little is sometimes the case, depending on what your partner was doing with it. Your lady parts may be just sore....give it a couple more days...if still hurting, get advice from your GP surgery....you can speak to a nurse.
We have a site doctor named Sqad who will give you his medical advice...right up his street, this question is....and maybe other good folk will give you their opinions too. I think you're probably young, so be careful... ok :-)
