I gained 5/8" girth from electric dry pumping, using a pump and release method like jelqing for about 6 months. Water pumping is quite different. I think water pumping is even better since the moist heat helps the skin stretch and improves circulation and the applied pressure in much different also. you should kegal to always try to acheive a larger volume of blood inside the penis. Wet pumping helps avoid the common skin discoloration and donuts also. Kaplin pumps are tapered which I don't recommend. Straight walls are best. Just bought a
Bathmate and plan to include it after my 20oz.
ADS and hang sessions for a total internal stretch before my supplements and zinger before sleep.
