I've got this little circle rash near the outside of my vagina hole. It started out like a month ago when I first notice it just appeared as a small cut. I thought I got it from wiping to hard with tissue but now it has became a little circle no bigger than a dime it's like the size of a pencil eraser. I haven't had sex since May 2012. And it was oral sex my ex didn't lick my p***y no longer than 5 minutes, he didn't know what he was doing so I made him stop. He didn't stick his penis in me. I have no clue what this little rash could be. It's no blister neither is it bumpy. What could be wrong?
