I have found a spot on my penis. Its not itchy or blotchy or white, or pusy. It is literally just a very sore red lump.
Does anyone know what this may be?
I havent had any sex recently either so im not even sure it could be an STD. Im not sure if i want to see my GP yet as i dont fancy going to see her if its nothing and will go away within a few days.

Anyone have any ideas?
