Penis skin cracked and peeled badly on glans and under leaving paler skin painful sensitivity to anything biospy no lichen sclerous psoriasis etc help?

Try... Great; chronic protracted benign skin conditions and skin cancer are ruled out with biopsy, now, it's logical to handle with keeping the affected area from further chemical and physical irritations if any, applying thin 1% Hydrocortisone cream daily x 7 days and see. If it's related with long foreskin, do circumcision. Detial? See doc timely. But it's hard to make DX without a direct look at it.
