Me and my girlfriend had some sexual activities on 2nd nov except intercourse. it was first time for both of us, we just did is fingering and handjob. she vomited next day & she is having pain in abdominal area, back and in hip. please help?

Doubt related: Unless you had filthy dirty hands as you were "fingering" her, I very much doubt the two things are related but anything except time. She may have a stomach flu, a urinary tract infection or an early appendicitis. She should be seen by her doctor to sort out what is what. The last thing you want is a burst appendix because she is afraid to be go to doctor after minor sexual activity. Get checked!
