i have 100 tiny painless acne on my outer skin of penis since 10 years (but glans is clean), they never discharge any fluid, but when i press or squeez them some white greesy matter comes out, i never had any kind of unprotected sex with anyone except my wife. But in the past i did frequent masturbation. I cunsulted my skin Doc. he said nothing wrong, u have got a oily skin, thats why this happens. But i want to clean them up. tell me the available medicines or ointments. plz
