Tried it for a while for the simple thrill of "lol I'm naked under this one layer" but no, not for me. Fact is I don't change my jeans/trousers every day (washing tablets don't grow on trees! It's bad enough with all the tops) but would probably have to without underwear as all the crotch sweat and pee droplets would get on them. (Ew). That is why we wear 'em!

Plus I always seem to buy work trousers with odd shapes down there, I don't know how, and they sometimes split. I don't want to be doing the walk of shame back to the car with my little corneos hanging out.
