My vag is on fire

Hey guys. So I'm not one to sleep around, I don't like to have sex with anyone I'm not comfortable with. I met someone last week and we both have fallen pretty hard for each other. Long story short, we ha A LOT of sex within 24 hours. This was a day or two ago. It was amazing. Closer to the end I was not getting wet enough, obviously, and we knew it was probably time to chill. Well here I am 2 days later waking up in the middle of the night to an itch I've never felt. It is more in my vagina than around, so I feel like it can't be dry from shaving. We didn't use a condom, but he didn't say anything to me about having anything to spread. I've googled it and came across possible causes such as yeast infections or other vaginal infections. And I'm just wondering what you all can tell me. I am going to try to go back to sleep and if it still itches like this when I wake back up I will be calling my doctor to set up an appointment. Thanks guys
