I'm Commando all the way. Have been for many years. Underwear is for pussies. My clackers need room to swing and dance. . I also like to engage in auto erotica through my pants when i walk behind hot chicks and I don't like too many layers inhibiting the friction.
A couple extra shakes at the urinal, shaving the upper crescent of pubic hair, and being markedly more careful upon unzipping are, collectively, a small price to pay for the infinite freedom going commando affords you.
