Smell

Patient: Okay i dont really know how to categorize this but it has something to do with my penis. i am a little embarrassed about this but since your a doctor i was wondering what is happening… i am 15 and their is this odor around my private and i dont get why it is happening…sometimes i would like exercise and it will get very sweaty down there and my underwear starts to get a horrible smell…i was wondering if there is like a powder or something to stop the smell but i wanna ask a doctor about it first..
