Pimple on the underside of Penile Shaft

[Scott E.]

I have a question concerning marks on the underside of my penis shaft. There is one "pimple" like bump that is obvious and then there looks like a small demarcation near it. I don't know if I am overthinking this or not. I have a picture.

Welcome to the forum Ken, it would be better if you upload the pics so we can suggest you accordingly. Does it itch? pain? since when have u had it?
