I do not do anything that would be considered exotic, simple exercises have always rewarded me well. Uli’s and hanging are the meat and potato’s; to get a big member does not require much more. The only thing that I would emphasize is that your arteriole walls are the most sensitive and the easiest to widen. The veins are more robust and resist expansion but they can be persuaded to move a bit.
I believe increasing the capacity of your penis to hold blood is an imperative, so enlarging the pipes is of paramount importance. I like to get my heartrate up before a PE session to enhance blood flow and generate a fresh supply of oxygenated blood cells, this will improve the workout and give greater expansion to the vasculature. Also, I like to have a mirror and target specific arteries and hold the squeeze for at least 3min, you can actually see the expansion of the arteriole walls. It is important to hold the squeeze to induce permanent widening of the vessels; it is through repetition and a disciplined approach that will result in significant volume changes. This can be done very efficiently with the hands and sometimes an elastic strap loosely around the scrotum and penis, I would never use a clamp or any other metalworking fixtures (for the love of Moses, its your penis).
In my way of thinking the widening of the pipes is the crucial element, it will affect your whole erectile circulatory system. This optimization is like changing out the 1/2 horsepower water pump and replacing it with a 5 horsepower roto-rooter. Hang tough, hang long.
