Shilow's thoughts on hanging.
Hanging has always been about the reduction of friction and having sufficient surface area to provide a significant mechanical advantage to support ever increasing forces e.g. It is easier to grasp a large diameter rope than a small diameter rope. Penis anatomy does not allow for grasping internal structures, it would be analogous to grabbing the internal structures of jell-o. All hangers form a “tourniquet-like” pinch that form a cylindrical collar that will not move past a certain point due to a larger diameter below (or plugged tissue).
So, in-order to posit the best hanging results it is suggested to have a semi-engorged penis (increased surface area) and a wide cylindrical collar (reduce friction/increased mechanical advantage).
