At 6.5 to 6.75 inches on a good day I have researched this to death. What I believe is that the best way to look as big as possible one has to be very slim. Look at gay porn and you will see a ton of very very slim males, lots of them with high avg to a little bigger than avg and their cocks look perfect. I am working on losing weight and losing it not too fast but as fast as safe can be. Working on the abs at the same time so that when I lose my fat pad their will be a nice set of 6 packs. A female gym instuctor told me once that all men have a set of six pack abs but most are under a fat pad. Now, being a pumper that does it for pleasure I have notice that I have made a small gain in girth that is sticking with me, but nothing in length. Will look longer with the disapearance of the fat pad, but I know it won't be. Also you should check out Thundersplace. It will tell you about the safe ways to pump and the unsafe ways
