I call this 'cord' as you call it a "guitar string" and it is a beast! It is the limiting factor for all of us. If someone tells you he doens't have one, he is mistaken. It is the "Septum" and it is the bundle of strength in the middle of the penis. If anyone ever gets that figured out, we will have the key to penis length. No matter what we do, that has to stretch before any length comes. I don't know how to stretch it. I don't know how to break it down. I can sometimes trick it and get a little length but it quickly raises his head and comes alive. It is the defense mechinism of the penis, I think. It protects the penis from damage. Maybe talking about it again will bring some light to the subject and someone will tell us of the success they have had in making it give. I think that
hanging and trying to reach the "fatigue" spot is one way, but then the septum builds up strength and it is harder the next time. GS
