big balls are not always fun. You sit on them. And they find their way into the most uncomfortable positions. lol.
Mine are pretty average, and I gotta say I would never wish for bigger ones. Sitting on them, crunching 'em on a bike, getting in the way if I don't wear a jock while lifting, etc. etc.
They do look cool on another guy, but I guess I'd just never want 'em.
