Yeast infection??

On Saturday I was at a party and ended up drinking and (attempting) having sex with someone. I know that when drinking, it may be hard to get wet and that's what happened to me. I could not get wet and it was painful when he fingered me and put his dick in. The day after my vagina was very tender and dry. Now it has a sort of pee smell and is itchy. The guy was a virgin and I'm wondering what it could be. Is it a yeast infection? Please respond asap(:
