Fewww.. I read the whole thread, some very interesting discussions and great posts there (tunica, fluid/blood plasma etc..) .
I have one or two thoughts to share.
Big gyrtha reached a full blown erection, clamped as tight as possible and let it subside, so that it was girthier than erect but in a flaccid state (the few times I tried that I hated it).
So could we consider this clamping set as girth work on an unloaded tunica?
Does an increased length in the cylinder prove a great stretching force is applied to the tunica lengthwise, and therefore, girthwise? I believe it makes sense.
If we believe pudendum and sparkyx hypothesis, wouldn’t cycle pumping be the best way to work on the tunica? That is, enter the tube half erect, quickly reach a high vacuum for 10-20 seconds, and then back down to 1-2 hg for a few minutes before repeating this stretch. Doing this I feel we would stretch an unloaded tunica greatly .
I recently started pumping, and have used this technique only for a week, but I just reached 1.5 cm further in the tube than when I pumped at low hg. Every cycle seem to allow me to pull further , when I back down to 1-3 hg for a few minutes, length decreases but is still longer than before the high pressure peak. For example I just finished my set, and at the end of it, when I stayed around 2-3 hg, I maintained a length a cm longer than my bpel.
Edema is minimal, I end up with thicker skin but no donut.
