I often get really smelly 'down there', sweat and things i guess, but its so embarrassing. what can i do to stop smelling other than having a wash?

Sweat : The smell is typically related to excess sweat and bacteria that thrive in the sweaty environment. Have you tried any remedies to reduce the sweating? There is a prescription medication called drysol for excessive sweating. Try drysol first and if not effective by itself, consider using baking soda to further reduce moisture and create an alkaline environment that bacteria do not like.
