What Is The Treatment For Fungal Infection In The Penis?

I think I have some sort of a skin disease on my penis. It looks like fungus. If I do not clean my penis within 10 hours, a pale white layer gets deposited on the surface. If I move the outer skin backward, I can see cracks on the surface of the skin. I had sex with a girl 3 weeks before. But i done safe with condom. Wats the reason and wat treatment need to follow..
