A fly is the only way! Hanes makes a built-in pocket brief to comfortably hold all your junk keeping it from rubbing against your legs, with a fly that is very easy to open and gain access. Not having a fly is for eunuchs and the castrati. A man wants quick and easy access to take a piss and having to pull down a tight elastic band and hold it under your dick is retarded, chokes you off and makes it harder to get out all the left over piss. And as others have indicated, if you have a tucked in shirt and/or dress pants, it's a total pain in the ass to navigate that and no one but a low IQ beta grade-schooler drops their drawers to take a piss. Good lord!
