Here is the reality. In a 2inch tube, I pack the diameter first and relatively quickly. That means all subsequent pull is on length. That pull is facilitated by adequate lube. By pulse pumping I stretch gradually. The fluid drawn into the penis would never occur under natural pressure. The vacuum also draws in abdominal skin and inner penis that would never be exposed under normal pressure. I think i have measured above 8" and girth over six, but when I am that aroused I am usually to occupied to get a ruler. As I have aged, 7.75 by 6" is all I could hope for. I have never been 9" by 6.5 except right out of the tube and that last only seconds. Caveat: I have pumped for a while and my penis is conditioned; I also use a silicone condom like sleeve to minimize bruising. Don't ever get on the ego trip that what you have in the pump cylinder is what you are in the bedroom.
