Unlike length which only has a single structure for reinforcement, girth is defined by two independent structures as referenced by Kyrpa. The twist action creates excessive strain longitudinally long before it could ever create enough strain axially. Then once it does begin to strain axially, it requires even more longitudinal strain to engage the pillars. This is because the attachment points of the pillars is also free to rotate axially so there is nothing to pull against.For length, it is inferior to simply pulling straight out which inherently targets whatever the limiting factor happens to be. Bundling places all strain on the outer layer of the TA and corpus spongiosum, when most are limited by the septum which is coincidentally least engaged through twisting. In short, unfortunately bundled stretches are worthless at best and counterproductive at worst, because if you reach the strain levels necessary for girth gains, you’ll have far exceeded the stress levels for length that will trigger your TA to toughen rapidly making any future girth or length gains impossible without a lengthy decon.
After racking my brain for far too long on the concept of girth and the physics involved, I’ve landed in the same place Kyrpa articulated above. Fundamentally we are only able to adequately target the girth limiting structures by exploiting Poisson’s effect. This is accomplished as he described by bringing the penis into a semi-erect state (but not fully erect), restricting outflow of fluid, and then compressing the cylindrical structure. Kyrpa described the method that I believe is most optimal and would target girth along and around the entire shaft simultaneously. Another version compresses the shaft laterally instead of longitudinally. Imagine a clamped semi-erect penis that is then placed between two flat surfaces (dorsally and ventrally) which are squeezed together. This would require girth expansion to the sides. I don’t like this version as much, but the concept is the same.
I have done a decent amount of bundled vacuum hanging straight down. The explanations of the physical properties provide some additional insight as to why it was not as fantastic of a exercise as I thought. The exercise seemed to help my tunica in the beginning but only for a short time until I became accustomed to the exercise after a couple of weeks. Then I started to over do it and use too much weight to try to replicate the initial sensations in my tunica. I did not feel my tunica stretching and expanding much at all.
However, I made a minor modification and had achieved some very good sensations of stressing my tunica and feeling expansion. While bundled, I grab my shaft with my hand and fully wrap my fingers around and hold it with some pressure. I then Kegel blood in. Wow, do to the fact that the blood has to force through restricted spaces I feel some very good expansion and pressure on my Tunica. I only do this modified version for a minute or two. I knew it worked because I am then able to twist my Dick even more right after I do this and I was already deep into the exercise and felt there is no way to twist my dick anymore. I know this isn’t scientific but the immediate feedback is a big indicator that it works for me.
I have not done this exercise in a while because I want to focus on the Ultrasound Length Protocol and I haven’t been able to fit routine PE regiment into my life at the moment, however I will try bundled hanging again.
What I came to realize it that I was using too much weight and wasting a lot of time doing the excerise and I was just making my Dick stronger and possibly building scar tissue or making the dorsal thickening tuff. I feel that the Ultrasound sessions have significantly released this scar tissue or dorsal thickening toughness.
All I need is lighter weight and only a few minutes of this exercise but with my Dick in my hand adding an even external resistive force for me to force blood through as I Kegel. I definitely need to be hanging weight to achieve the expansion tension as when I do it without weight the sensation is not intense. I will say that my Dick has to be twisted a lot to feel the effects I mention. I have to check my logs but I belive I was up to 720 degrees.
This is definitely not an end all be all exercise but I do feel that just a couple of minutes of IR heated bundle stretching with this modification is something which has given me targeted girth gains is a particular portion of my shaft MSEG. I feel it was a good way for me to stretch out my Tunica and then go into my cylinder air pump and noticed that my shaft expanded easier that when I did not perform this exercise first.
Sorry if this sounds like a derail but it is about Tunica expansion and the forces to make it expand. It is something I will certainly try again when I get back into converting BPFSL to BPEL but first I have to focus on BPFSL gains.
