Hi, I'm not sure if this will get answered but I thought I'd try asking
Right at the inside of my vaginal opening... on the inside of my labia minora I occasionally get a rough spot on either side that resembles a very small vertical cut on either side
It doesn't hurt and it isn't very big but it bothers me
I'm worried it is some kind of STD but I don't really think it is because I have been tested and they came back negative several times and it only comes around the time of my period then goes away... then comes back again around the same time again and goes away, etc.

Does anyone know what this might be?
