My husband has scaly skin on his scrotum , which he is constantly scratching. The skin flakes and sometimes he even scratches to the point of bleeding . It does not affect his penis, or anything else. He s too embarrassed to ask anyone about it, but it s killing his sex drive and I want it fixed! Is there anything we can do to fix it at home? He s tried jock itch creams, but they don t seem to help other than some soothing the itch briefly, and others even make it worse.
