Depends. Usually I just throw on whatever I put my hands on first. But usually I wear boxer briefs or boxers. But I hate the really large boxers that just make me feel warmer all day.
Boxer Briefs, I find the lack of support in Boxers uncomfortable.
Same... Sometimes I like to hang out in my underwear.. And with boxers sometimes my stuff kind of flops out for a visit. I guess not everyone in my home is down for the visits. So I wear boxer briefs.
