Not haole rot but I got a sick fungus on my weiner first trip to el sal never changed outta my trunks or showered for a week. Doc thought it was herpes at first. What a relief when that cream worked. Stay dry and clean!
Gold Bond Powder, after you shower and dry off. Apply to your crotch area.... and feet as well if your wearing shoes all day. Cotton socks don't help either for blisters or fungus.
