I got this 2 weeks ago from delivering in the hot southern heat. There was a lot of moisure and sweatiness down there perfect to create an environment.
So i put some Lotrimin on it. It went away. Now the past couple of days its kinda been bothering me again. I wanted to know if going "commando" from time to time or maybe being a guy and possibly needing to switch out all my boxers for new ones might have anything to with creative a type of fungal environment..i.e..."A warm, damp environment allowing the fungus to cultivate greatly contributes; especially with tight, sweaty or rubbing clothing such as jockstrap or tight undershorts." - wikipedia
