I had a friction burn on my penis head. It would turn red, then scab over, then look ok a day or two and then do the same thing over again. This went on for 3 months. I had STD tests that came back fine. First doctor prescibed bacotine or something like that, it did not work, second doctor told me to keep vasoline on it, that did not work. I tried aloe, hydrogen peroxide, neposporin, psorisin, even vagisil and soaking it in oatmeal, nothing worked and I thought my life was over. The third doctor prescibed an anti-fungal cream called Clotrimazole Betamethasone Dipropionate Lotion and it healed up within a week!!! It was expensive $120 for a small bottle but I would have paid 10 times that!!!!
