It is common because its such a hot area and people sweat a lot. Wear briefs that are breathable, use cotton stuff. you can either use deodorant or baby power to stay dry down there. Also make sure you towel down good when you get out of the shower.you can soak your briefs in antispetic solution like dettol
for 25 minutes.try to consult doctor
