Really Bad Chafing with board Shorts.

[crayola110]

Hi so I've been surfing more recently and when I go out with my board shorts I tend to get really bad chafing on my balls. I was wondering if anyone has any recommendations for what to wear underneath my boardshorts to reduce the rubbing and chafing.
I've tried just wearing cotton underwear, but i think it does'nt work well because the cotton stays wet the whole time. Is there some sort of nylon underwear that you can wear underneath your boardshorts?
Any other suggestions??
