I cured mine about a year ago

I smothered the head of my penis and the retracted foreskin that was red with Aquaphor for an extended period of time (probably a couple of years); I don't know when exactly the infection went away, but likely much shorter than that.

You don't have to do it every day, but I think there needs to be a barrier between the surface of the penis and whatever is agitating it within/ ontop of the foreskin at all times. In saying that it is probably better to do it every day if you can, at least initially.

I cleaned my penis in the shower, then I applied the Aquaphor 2 hours or so later, but doing it right after it's dry will probably be just as effective.
