Ask anyone that I work with (or live with) and they'll tell you that I am anything but an uptight guy. I'm a pretty laid back fellow, but I gotta have everything in its place down there. Boxer briefs only. Two reasons: they keep things in check and my wife loves them. 'Nuff said.
I'll go commando on a weekend when there's nothing to do and stepdaughter isn't home, but I seriously cannot get used to things moving freely when I'm trying to get any kind of work done. Forgot about being with other people knowing everything's untamed below the belt. I get too paranoid. Probably because I'm not a showoff. Early pubescent trauma.
Can't do boxers, no support. Can't do briefs, not enough material. Boxer briefs work just fine, thank you.
