    DP 4000

    It is good to hear from you, and I feel the DP 4000 is by far the best pumping instrument to ever be invented. In my counseling, if the student has a budget I recommended it eagerly. With the stallion cock cushion being worn while pumping you get a uli affect, in other words as the pump progresses the cock cushion at the base is pushed somewhat forward by the tissue inflating behind it increasing the tunica pressure interiorly while the pump works on the exterior. This is a great discovery, since using your pump I have a gained an inch and a half in girth, going from 5 1/2 inches to 7 inches. And I'm sure I can get larger if I wanted to, so needless to say I'm ecstatic about this device.
