I'm a slim man, but I've discovered that after even a short hike I start to get chafed in an area I didn't expect—on my rear end, very close to the anus. Needless to say this is quite an embarrassing topic to bring up in camp with my fellow hikers. My tight-fitting 100% cotton-free boxer-briefs keep the chaffing in other sensitive areas at bay.

I guess I'd like some solidarity, does anyone else get chaffed in the same area? What products would you recommend to prevent chafing in the future?

Thanks.
