Hmm the purpose of underpants aka underwear ...they cover your most private and delicate parts but dont pants and such do the same?...no i say! they are like an under armor for those sensitive parts with out them things may move around in unwanted places (for guys anyway) and for the ladys there rough jeans might brush up ageanst those parts and well use your imagination..i think live wouldnt be normal with out those blessed cotton undergarments just try to imagin all the chaffing and such you would get if everyone were to go commando all the time you would walk down the street and see people walking all bow legged..not a pretty site...well thats my thoughts...what about you all?
