Can fungal condition happen to ccumcised man without being sexually active for years penis skin peeled on glans under leave scars thin raw skin sensit?

Of course. Fungi are all around and nobody knows why a patch will set up on any particular place. Your physician can let you know if this is a fungus. I see you've had a biopsy -- this will let you know whether this might be premalignancy instead. These fungal infections are easy to treat. Best wishes.
