Hello. I have an odor coming from underneath my testicle sack. I have had this for a few years now and I have noticed some odd things after sweating awhile. My briefs/boxers start to rot wherever the certain type of sweat is on the garment and it's a dirt/brown colored stain. The sweat has a strong odor immediately after I begin sweating. It gets even stronger if I don't ejaculate. The odor is kind of difficult to describe. Its mustier semen type of smell. I am concerned and I was wondering if I should go to the doctors. I am embarrassed about this condition so If it is necessary I will go to my doctor but if this is something that can be cured with a simple pill, I will do just that. Thanks for your time and your feedback!
