Anyone know what this could be i was thinking that it could be a new mole, but am unsure, i shouldnt have an std as i havent been sexualy active for a very long time, but its worrying me im not sure how long it has been there probably max a couple of months, its flat and there is a slight discouloration next too it, its darkish brown / grey color. there is a slight itch but that could be because i keep touching it.
