you see your cock pumped up like a summer sausage and feel it twice
as heavy as normal in your hand, it's amazing. How could it get
so much bigger this way than it does when you have a massive hardon?
answer is Time x Pressure...
you have an erection, valves in the blood vessels that supply the
penis close, trapping the blood so that more flows in than out,
until you get hard and reach equilibrium.Your level of excitement
determines how many valves close and how tightly, so you start out
soft enough that your partner can tolerate penetration, and end
up hard enough to drive your partner wild and deliver your load
you've ever been erect for a long long time, or worn a tight cock
strap, you may have noticed that your cock gets larger than normal,
and a little spongier feeling. What you've got going there is a
bit of a pump!
you pump, you create a partial vacuum around your penis, so the
fluid pressure inside it exceeds the air pressure around it. Under
these conditions, the penis expands until the pressure is equalized;
basically, it compresses the space around it and thus raises the
penis has two ways to expand: by filling the corpus cavernosa with
blood, and by puffing up the rest of its tissues with lymphatic
fluids, which seep into them from the blood vessels. Thus, when
you pump up, you'll notice that you stretch out quickly at first,
until you have an erection or at least the sensation of an erection.
This is your cavernosa filling up. Thereafter, you expand much more
slowly, because it takes a long time for lymph to seep into your
tissues. At least, it does until the pathway is established - so
you'll find that towards the end of your session, the tissues will
puff up faster.
the cavernosa can fill up quickly, you can respond rapidly and comfortably
to fairly high vacuum pressure at the start of your session. But
it's a bad idea to start with high pressure, because that pressure
acts on ALL your tissues, not just the cavernosa. Therefore, you'll
be forcing fluids into your tissues faster than they can adapt,
and you'll put too much pressure on your smaller blood vessels.
you should start with minimal pressure and let your cavernosa fill
up at a leisurely pace. As your dick expands, you'll need to withdraw
more air from time to time to maintain that level of vacuum. As
your tissues adjust, you'll be able to gradually increase the pressure.
Increasing the pressure helps you maintain your rate of expansion.
But you have to limit yourself to a rate that always feels comfortable,
otherwise you might stretch the tissues too much.
you pump you are trapping blood and fluids in your penis. Trapped
blood gets depleted of oxygen, thus starving your penile tissues.
Therefore, you need to refresh the blood supply often. One way to
do this is to "milk" your cylinder, thereby pump-jacking
your dick. Another way is to take frequent breaks from the tube
- about once every 15 minutes, or whenever your skin looks dark
or you feel achey. You should also start semi-hard rather than fully
erect, so that your blood valves are wide open.
the early stages of your session, your penis elongates noticeably,
but it expands even quicker in girth. Basically, you elongate to
your normal erect length until you pack your tube from side to side.
Thereafter, the vacuum pressure is focussed on your head, pulling
your penis forward. From here on you get really long out as the
suspensory ligament that holds your penis into your groin stretches.
This is when you feel the most intense pleasure from pumping, but
again you have to contain yourself - too much pressure for too long
may cause blisters or bruising of your head.
typical pumping session lasts anywhere from 30 minutes (a quick
pump-up before sex) to an hour (a nice moderate pump) or several
hours (an occasional "get huge" session). When you take
it nice and easy, you'll be amazed at how big you can get and how
good it feels. Do it right and you'll have bigger, harder erections
for a couple days afterward, and you'll fill your pants like you've
never filled 'em before!
you've had the theory, let's get on to the practice. But first,
more words of caution...
