Wear pants and under garments made of cotton - no polys or synthetics.
It's worth considering tactical high-tech poly underwear, the kind worn by athletes who in humid conditions you may bet sweat a lot but never appear to have stained clothing.
Depending on severity you could try slightly dusting the area with talcum powder. Much debate goes on about baby talc being better than ordinary talc; however, the only way to find out is to experiment with both. Some people oppose this method altogether because they say when the talc mixes with sweat it clogs, but doesn't this tell you it's absorbing up the oily fluid.
Cornstarch is supposedly said to be affective.
A great percentage of sweaty folk use underarm deodorant on the small of their back, how true its effectiveness I do not know.
try OTC antiperspirant and see if that helps. If specially formulated antiperspirants to treat heavy sweating don't work for you then you may require prescription medicines like anticholinergics. Other types of treatment are ontophoresis, botulinum toxin, and surgery but only in special cases. Always consult your GP before using unfamiliar products or practicing unknown solutions to stay safe.
