I've worn different brands of thong, and Calvin Klein makes the best, most comfortable pair that I have yet found. As with their briefs, the pouch and waistband are extremely comfortable. I think a lot of guys might be worried about wearing a thong because of worry that someone might see it in back, but with the broad waistband there's really nothing to worry about. No chafing or anything from the string part, either. Just very comfortable and very sexy.
