Ok, if you have hair on your ass, the only reason to get
rid of it is if you want then both played with. It's less fun for
the girl if she has to pick hair from her teeth every now and
then.
If you're concerned about pubic hair above your genitals then
buy a small pair of sissors with blunted ends. Using your fingers
like they do in salons, pull between two fingers some hair without
pulling the skin and trim off the hair about a centimeter. Do this
all over. While too much hair looks like you need grooming, no hair
looks artificial. Just like a hair cut, a trim will look neat and
tidy. If you want certain areas to have less hair to balance out
the look, then trim those areas closer to the skin.
A good guide to a good trimmed look is to trim the hairs closer
to your joystick closer as well as the sides where it fades into
your body. The hair when wet should not cover your balls. You
should be able to see some skin through the hair. Hair that puffs
out may be trimmed closer, you'd ideally want it to stay about a cm
or so from your body. You may have to trim it about once every two
weeks or so.
Balls have to be shaved. Take a hot bath and that will relax
your scrotum and make it hang looser. If you have a lot of hair,
you may do some spot trimming and if that looks good enough,
you may not have to go further. Be very careful you don't cut
yourself. Use your fingers to push the scrotum against your
testicles and stretch out the skin and use the sissor to cut off
excess hair very slowly. VERY SLOWLY.
Otherwise lather up and pulling your scrotum skin smooth, shave
your balls. Remember if your skin folds, you may nick yourself and
cause yourself pain. Hair on the balls tends to grow back slower.
Try not to shave just before having sex. Do not attempt to wax your
balls.
For the area between your balls and around your ass,do it very
carefully with a lot of good light and mirrors and lots of shaving
cream and water until you get the hang of it. Don't mix your razor
with the one you use on your face. There is a disadvantage
that once you start, you'd have to keep doing it or the hair
growing out will cause you discomfort. Razor blades are pretty
expensive.
A more painful but better solution may be to wax. Buy one of
those prewaxed strips and follow the directions. An advantage of
waxing is the hair doesn't grow out as uncomfortably. Also I'd
advise you to use an antiseptic powder over face creams if you
experience discomfort in those areas after shaving or waxing.
Also not to be done just before sex. Try to give it a couple of
days for some healing to take place, few people will enjoy seeing
you bleed on them.
I hope I have been of help.
