What Is The Treatment For Peeling Of The Skin?

Hi, I feel i might have a penile yeast infection. The symptoms i have now are,
1. Dry skin that peels off near the penis head (looks flaky) and an itching sensation.
2. A couple more itching areas on the inner side of the thighs close to the groin area that is white and turns red sometimes on rubbing it incase of an itch.

Could i take the ketaconazole medicine suggested all over the internet (diflucan). Please advise me on what steps should i follow next.
