lol.. is an interesting one.
heres my routine.
prob do it once or twice a week.
get a comb and some scissors, cut the pubes the length of the comb (very short) and don't take TOO much time on it all. then shave my **** on top and underneath, to get those stray hairs and give it a nice even look, then i shave all over my balls, very tedius work. but a good end result.
and for me, it only itches my balls when the hair is probably 5 mm long, then it seems to scratch my balls with the sharp ends of the hair. (worse on cold days when ur balls are tight).
my ass i don't play with. however, i do want to wax my legs and ass, just the once for over summer. although summer is now almost half way through, so i prob wont.
