>… by pressing down rather than simply pulling out with the other hand, you get a better stretch due to the leverage that can be achieved by putting your upper body weight into the stretch. <
I had never really thought of this specific reason before. The V-stretch hand position apparently allows you to position your body so that your arms can generate more force. This is a good thing. However, this V-stretch advantage does not discount any of the counter arguments I made against the original V-stretch theory. My original reasoning that a primary advantage of V-stretches was simply the use of two hands as compared to one hand is similar enough to the point that you are making here that I now group these two points together. I will mentally add your point to my original opinions. I would state it as follows:
One of the primary advantages of V-stretches is that it incorporates the use of both hands, thus adding to the total amount of tension you can develop within your shaft. Whats more, the unique grip and arm position of the V-stretch allows you to put more of your upper body weight into the stretch.
> Also, if you face the septum as a limiting factor, by using the A-stretch for example, you can stretch the entire top of the shaft more than the bottom, having the added benefit of specifically attacking your limiting factor. <
This is what I meant when I said: “AV-stretches localize the forces at the point of the bend”, but you stated it in a different way, perhaps clearer.
> By using a large round fulcrum, like the wrist, the focused tension can be diffused in a larger area of the shaft. I think. <
You’re right. I think. However the larger the arc of your fulcrum, the less localized the forces will be. So you need to decide: Do I want to really seriously stretch a small volume of penile shaft, or Do I want to spread out the forces over a wider volume and accept that the forces will be less severe than if I localized them to a narrow band of shaft.
Now would be a good time to reiterate a subtle point that I previously implied but never outright stated. Generally the more points of contact between your hands and your penis the better grip you will be able to sustain and the more force you will be able to generate. However, I do admit that this is not always the case due to the very complicated 3-dimensional and deformable nature of the penis. For instance, if you pinch your penis between your fingers and thumb in the same type of grip as a jelqing grip, you will be able to create a high pressure chamber of blood (a so-called ULI chamber) ahead of your fingers and you will be able to impart a force into this chamber (and subsequently into a tensile force along the shaft) that does not rely on frictional forces.
I bring this point up because I think your use of your wrist increases the frictional forces you are able to generate. So if you are also pulling outward from your body with your wrist you may be able to pull harder than if you were using a smaller fulcrum.
Hopefully all this theorizing doesn’t go to waste.
