Just today I felt discomfort where my vagina lips meet my butt cheeks. In between those spots is VERY sensitive. It hurts to walk, to stand, ANYTHING. It looks like a small rash, A VERY PAINFUL one at that! I don't notice bumps or anything, the skin just hurts SO bad!

I just got off my period today (I use pads).
Would the pad rubbing me when I'm not bleeding cause this irritation? Have not recently had sex so I'm positive it's not an STD.
