Yes there is. Pumping Works. (hold the hate mail!) It works the same as lifting weights, or body building. "You stop, it stops"
.. my answer does NOT pertain to the pumping seen on Newart.com, or in Pump Mag. ... It does pertain to pumping in a tube that will maintain the shaft at the same size it is, not liquid engorged. If your cock is 1.5" Dia. You want a Tube that is as close to that as possible. The tube must NOT be a cheap one, it cannot flex, or colapse. The tube must be several inches longer than what you are trying to achive, and it requires a VERY GOOD Pump, Pref. Electric.
... A good lube, for the inside of the tube, and an obsobable Flesh relaxer like,, Like hell there is only one.. CoCoaButter. For the shaft. Enough patience to work for a predetermined period of time 3 to 4 nights a week.
... It doesn't take a great deal of work, it only takes the patience to sit back with out experimenting with how much Vac. you can take. It is NOT the how long you can stay in a tube. It is Reps. just like lifting weight, or Body building. BTW, in this case, if there is pain, there is NO gain.
