I've large balls, and I'm hung a bit farther back, so I have to be careful not to sit on them, and I can't count the number of times I've had to adjust them when getting out of a car. Back when shorts were shorter, I had to be careful and make sure they didn't fall out the leg hole. (It may be hot, in porno shots, but having a friend say, disgustedly, "Hey, man, I really don't want to sit here and look at your fucking balls, okay?" is rather humiliating. Especially when you're in public.)
