Hello there
I am a 17 year old male I have many little small pus filled spots on my penis and scrotum that sometimes itch. I have popped a few and there is a bad odor coming from them. There are also some bigger spots on penis and all of the spots are on the underside of the penis.
I've had really small spots for about 3 years, but I just thought perhaps that's puberty, but now I realise it is not and is an infection of some kind.
I've seen a doctor, and he just said it was barber's rash from shaving, but I wouldn't suspect that barbers rash spots would rich the head of the penis.
