I did it but I think I overdid it. Although
the spots were on
the underside, I used to apply it all
over my penis. After a week, I felt slight burning and itching on folds of shaft skin (I'm circumcised). I stopped applying it on that part. The white spots appears to be gone, but I have serious irritation on the folds of shaft skin. I tried to stay at home, ventilate it being naked in front of a fan and used baby powder for a couple of days.
