Mine are slightly larger than average, being 3 inches on the long axis and about 2 inches on the short axis, and I'm glad to hear someone say that they prefer ones that aren't loose and dangling. Mine are sort of high and... firm (that description paints quite the wrong mental image, but neh). My penis hangs lower than the balls, so if I'm going to sit on something, it's inevitably my penis first - thank goodness. Balls are so sensitive. I'm sure it would be worse if I was a dangler.
Actually, on the sensitivity issue, the annoying thing about larger than average balls is that pretty much whatever you wear, it feels a little tight in the crotch: not enough to be immediately distressing, but enough to be irritating after several hours. My sympathy to some of the posters above who clearly have it a lot worse than me in this regard.
