So i've had this small red spot on my penis head since i was 15 years old (2 years now), back then I was not sexually active and it just appeared out of the blue, and i've had it all since.. It's just a small red spot about 2-5mm wide doesn't hurt or anything..What is this? and preferably is there any way it can be removed? The visual appearance is frustrating and getting questions during intercourse as to what it is.
