My boyfriend has dry skin on tip of his penis he said its from masturbating. he keep peeling scabs what should he do?

Stop and see...: Does he have long foreskin? Was he circumcised? For now, stop over physical and chemical stimulation for next 1-2 weeks, gingerly apply 1% Hydrocortisone cream daily for next 3-5 days, and keep the affected area as dry and clean as possible but the cream used. Besides, practicing healthy lifestyle without overindulgence and obsession will benefit anyone on how to live a long happy life. Best.

See doctor: To see what it is . It could be an std or another skin condition. And he should stop pealing the scabs so that it can heal.
