There can be a few causes for the scaling behind the ear. Some of the common causes include: 1. Seborrhoeic dermatitis 2. Psoriasis 3. Fungal infection It will be good for you to see your doctor or dermatologist for a proper assessment and diagnosis.

Thank you for your interest in such a commonly encountered problem at the clinic. Quite a number of potential causes for dry skin on penis and penis skin peeling came to my mind. 1.) Dry, unlubricated sexual acts, including masturbation or intercourse, can cause enough friction to irritate the skin of the penis. Irritation of the skin of the penis can culminate in itching, flaking, and peeling of the skin. Opt for a water-based lubricant if you have sensitive skin. 2.) Wearing overly tight pants or pants without underwear can also cause irritation from friction.
