I once had the same problem. The guy was WAY too rough with his fingers which made my labia all swollen and bloody. It took three days till the pain was gone but I was still bleeding a little bit a few weeks after when having intercourse.
This is completely normal. It was just too sensitive and too rough for what your vagina is used to. Happen to me to where the point I was freaking out. But it's just swollen, should be irritated for a couple days. Ice it down take Benadryl and you should be fine. Don't play around for a good two weeks before doing anything and use pads around period time.
