slightly pink marks on penis

hello, recently noticed these marks on the under side of my penis and was curious to what they are. i previously thought they were ingrown hairs but they havent gone away. theyre flat to my skin and don't have any itching or other side effects.

very close to the base of my penis near the balls on the under side.

I have just posted something very similar as well. mine seems to be underneath.

I am trying out a cream for Eczema & Dermatitis to see if it will help to clear it.

any progress/updates?
