itchy feeling

Marissa
Okay ladies I'm hoping someone can tell me if I should be worried or not. I think it's the new soap in my shower but 3 days ago I got a shower and since then it feels like someone rubbed my vagina with sandpaper like it was burning and there was an itch... Well last night I got a shower and went to my boyfriends house and as I was laying in bed while he was in the shower I started to notice this really bad itch and it just wouldn't go away! It was soooooo bad and it's still there! This morning I went out and got some vagisil but the feeling is still kinda there anyone know what it could be? Nothing out of the ordinary just the extremely bad itch and the burning feeling sometimes
