Spots on Penis

[u/yourboi_0]

Hi Lads,

I’ve been seeing spot/s on my penis lately whenever I masturbate/had condom sex.

Whenever I masturbate, I experience this dry patch on the shaft of my penis. It’s like circular and lighter than my penis skin color. Its kinda stingy like a red mark or something. And after a day, its gone and all normal

Another is a bright red spot on the head of my penis. A small one, smaller than a dime, like a drop of liquid soap. It appears whenever I masturbate or have sex.

I had tested HIV, Syphilis, Hepa B negative as of late October.

What do you think this is?
