Vagina Problems

So this morning I noticed my vagina/vulva was sore but I've been having a lot of sex recently (with a new guy) so I figured I was just raw. As the day went on I started to get a little itchy but I didn't think much of it. As I'm going to bed I decided to take a look just in case and it looks like the skin of my vaginal opening and just around it is kind of peeling and there's so white-ish discharge but not a lot. The first time I had sex with this new guy was Saturday and we didn't use a condom (we have been since then) he says he's clean and he appears to be but I know some STIs don't show symptoms in guys. There's no pain when I pee, just itchy, pain, and skin peeling. I know I have to go to the doctor about it, I was just wondering if any of you ladies have had an experience like this and could help me figure out what's going on? Any help is greatly appreciated.
