Dry and itchy patch on vagina... help?

Hey, I’ve recently have gotten itchy down there, only the left side of my Vagina lips.it started in my inner left side and now that’s gone it’s on my left lip.. I’m a virgin so it can’t be an STD. I wash regularly and religiously at least twice a day. I can’t really see done there. It’s dry and because it’s dry it’s itchy and the skin fills flaky, I put rash cream all over that left side from top to bottom and when I went a bit lower it stung a bit! Idk what is. Does anyone know?
