key to pumping success is to control the suction.
need to give your cock time to adapt to it. Start real easy and
very slowly raise it, keeping it comfortable at all times. Do
that, and you'll get bigger than you thought possible. Try to
hurry the process and you'll just end up sore and bruised.
tissues of your cock are elastic and, to some extent, plastic.
For a brutal analogy, think of silly putty, which is also elastic
/ plastic. Pull it nice and slow and you can stretch it a mile.
But pull too quick and it snaps! Same thing with your tissues,
at a microscopic level.
if you start with very light suction and increase it very gradually,
you'll actually stretch more and be able to go to higher levels
of pressure than if you get aggressive. I can tell you from experience,
earning that 5" Hg max after 2 or 3 hours of discipline is
worth it! The sensations are incredible!
other thing to do with pressure is to vary it up and down. This
produces more action in your tissues, improving circulation. Bagman
has written an essay "Effective
Time", showing how you'll get a better pump in less time
by easing off the pressure frequently to open up the blood vessels
and lymph vessicles.
you should go by feel,
but here are some approximate vacuum levels in inches Hg.
every man, start at about 1-2" Hg.
beginners, always keep the pressure below 3" for the
first 3 weeks (that's below the green line if you have a MityVac
gauge). Thereafter, slowly raise the pressure to 3" by the
end of your second set, 3 - 4" by the end of your session.
intermediates (6 months or more), end off at about 4"
(always stay below the red line on a MityVac gauge).
can go anywhere up to 5" - 7" Hg. Work your way up to
this very slowly over the months, always testing your limits.
Vets can still get good results finishing at 5" Hg. Sometimes
you just want to go higher because it feels so good or you're
reaching a new max size.
can get much the same results at lower pressure by taking more
time. Note however that the skin (and foreskin) pump up more slowly
the corpus cavernosa, so long sessions tend to increase "bloat".
easy to tell if you're using the right amount of pressure and
pumping the right length of time. Unless you're doing a special
session to get huge, you should always be able to achieve a full
erection shortly after pumping. Your erections over the next
day or two should actually be fuller and harder than normal.
you pump too hard or too long, you may find that your penis looks
dark or has tiny red spots called petechia. And if you go way
overboard, you'll get bruises and water blisters.
good way to lessen the risk of using too much pressure is to pump
wet. Pumping wet gives you the same expansion with less suction.
the biggest pressure problem is overdoing it near the beginning
of a session, before the tissues have had time to adapt. The best
way to avoid this problem is to get a real good
seal, so you aren't overpumping to compensate for losing suction.
