Thoughts and Concerns Herpes, HPV...?

I recently had sex with this guy. After we had sex, my vagina was extremely swollen which has never happened before. He came on my stomach and it made my stomach extremely red. We did not use a condom, but I'm curious as to what it could be. I do have some irritation right now, and have a few small white spots. Please Help!
