Concerned about cuts and dark areas on penis...

not sure what this is but dark areas, dry skin and open sores have appeared on my penis on foreskin and head. i have not been sexually active in half a yr. i masturbate but i dont believe it to be an excessive amount. although most of the time without lubrication.. i have had quite a bit of stress lately as well as having had shingles on my back in the past so maybe related to that… just looking for hopefully some more insight.

u have some kind of skin issue going on u should see a dermatologist

Agree with Kim, this is a severe skin issue, the specialist as Kim states is a Dermatologist that you need to sort this.
I can help you further once you have seen a Dermatologist and have a diagnosis and initial treatment put in place.

usually when it becomes severly discolored like that its due to infection or the blood not circulating as it should u most certainly need to see someone as soon as possible ideally
