I need help!

So my boyfriend and I had sex a couple nights ago and everything was fine, but out of nowhere it stared hurting. Then the next few days my vagina started having discomfort. So this morning I looked inside my vagina and I have a cut in it, I’m having weird discharge, my vaginas red inside, and my vagina hurts/burns. Anyone have any ideas on what it can be?
