My husband has a burning sensation on the head of his penis. no pain with urinating. could it be our hot tub or laun. detergent, or shower soap?

Clarification: Is the burning at the tip of the penis or the entire head of the penis? Is the burning constant or intermittent? Is there discoloration in the area of the burning? When did this first start? I am happy to help, however it requires additional information.

Yes: Irritation of the sensitive tissues of the genitals and face can occur from exposure to chemicals with fragrance, different pHs or caustic ingredients that can be found with soaps, detergents and pools/hot tubs.
