So I Had Unprotected Sex With My Boyfriend For The

So I had unprotected sex with my boyfriend for the first time. Now it's hard to keep my vagina wet during sex and, it's starting to hurt during intercourse. Meanwhile my clit seem to be irritated and I think I'm having a lil puss coming from my clit, and my libia and the opening will hurt for a couple hours and stop. What is wrong with me?
