For most my life, it was briefs. Then I found the glory of silk boxers. I never realized how much sweatier/smellier briefs made me. I guess I always thought I would have a problem with erections if I wore boxers (and for a while at first, I did :-) Now I love boxers. For the reasons stated above, 'the last couple drops' and 'protection' for the pants, I can't really see myself going commando.
However, I am somewhat of a nudist when at home. I'll put off putting anything on as long as I can, somewhat to Milady's chagrin
