I like guys who wear boxers!  Boxer briefs are do-able and tighty-whitys are a no-no (sorry for those guys who wear them).  I just can't get turned on with tighty-whitys. As for me, I usually wear thongs or bikini cut underwear.  I haven't tried the so called boy-cut underwear yet because I don't think they look right on me.  And I haven't tried the no underwear thing yet.  With some of the pants I own, I don't know how comfortable that would be! 
Oh, and Rob (Mt. Biker), nice visuals from Victoria Secret!
