penis skin

i was reading some studies about androgens insensitivity and i was remembering 1 thing:

when i was on propecia (at my 6th mouth ) i noticed some/many marks/blotch on my penis’s skin who went away within 3 weeks…

this is my question: does anyone had the same issue?

i think this marks could have been the dht absence from my dick’s skin…
and i think this could be a reason of no sensibility of penis that we have.
skin has never come back to its original situation.

Last thing, my hair doesn’t fall like they used to, than this issue is due to 5 ar receptor in the tissues.

i will ask for a skin fibroblast to understand what about my dht receptors.

yes, i also have some/many marks/blotch on my penis’s skin…
