You might want to try boxer briefs, guys- I gave a set to my husband and I noticed he always wears them with his kilts now.



from what I can tell, they'd give you more coverage than a pair of tighty whities but still the same feel of movement. Plus they come in different colors, I think I bought his at Tarzhay, I mean, Target, and they had colors from black to blue to plaid to white!
(Oops, I just saw they were mentioned, sorry, didn't mean to repeat!)
