Dark Spots On The Corona Of Glans

I’ve got a couple dark spots right on the coronal ridge that I didn’t notice before starting PE, very small, smaller than a pimple.

I stopped PE and have waited a couple weeks and they’re still there.

They fade to almost nothing while erect, are they bulging blood vessels that get stretched out?

How worried should I be? Has anyone experienced something similar?

Superficial capillaries and they are nothing to worry about.

Please warm up thoroughly to avoid such spots and similar problems.

Thanks for the replies!
