Boxers!!! If I go back to tighty whities, well... I'll just say that the tiny threads in the corners and the band that goes around the waist that used to leave ridges on my skin... I HaTeD that. When I first tried boxers, they felt awkward with the unfilled space. But I have grown to use them(15), and it feels pretty good. P.S. there was this one time when I put em on backwards, and I couldn't find the hole in it when I went to the bathroom...
