Collagens are strongest axially. The particular arrangement in a penis resists alteration in (analogously) the 'cardinal directions' as the tissues are laid out: Longitudinally - North to South, vs changes in length ... and Circularly - "East to West" vs changes in girth.
To break down and remodel the tissues in those directions, you need a
lot of time and/or a
lot of force. [ * ] Which is all doable, but there are ways to reach the goals more quickly.
[* And/or added heat between 104 and 108 F to increase pliability of the collagens].
Since their strength is highest in perpendicular layers lain to cardinal points, diagonal torsion (such as bundled stretches) -
is- deformation. -- As is deflection of the tissues as well by various jelq variants .. jelqs/SSJs etc are like a rolling ring of compression, stressing the tissues 'down/inwards' (and to some extent also outwards) in a vector where the tissues are less resistant to force and are easier to destabilize. [**]
If you can get the tissues to undergo stressors in weaker vectors, where their strength and therefore structure is more easily compromised: such as diagonally (via bundled stretches, directional pulls [behind the cheek etc], A/V pulls, cranks) -- or deflection (via jelqs, or SSJs and etc, or the
SRT expressive thing whos name I'm jammed up on at the moment) then the various fibrils can undergo breakdown more easily for less resistance during additional PE exercises, for greater remodeling/gains during healing and/or active healing. In sports physiology (like muscle-building) they call that 'Pre-Fatiguing'. The usage is different but the term fits here as well.
I had a longer 'post' (i thought) on this, .. tried to find it but turns out it was a PM conversation that I probably shouldn't link to, and don't know if that's actually possible anyway. The above is a decent retell, hopefully it made sense. ((Did run into the original link for Kelly's TED Talk on this subject though:

[** This is making me wonder now if water pumping's superiority over air pumping .. I've never used either one .. might largely (no pun intended) be based upon the likelihood that the users of waterpumps are
very probably using water of comfortably warm temperatures .. near or at the range for increases in collagen pliability .. rather than what's less likely - inexplicably using water that's uncomfortably cold for no rational reason. Since water will add or remove heat 9 times faster than Air, 'room temperature water' would feel uncomfortably cold .. like a cold shower. The simple act of having the water be comfortably warm would be right at the range for heat-related pliability benefits versus the normal strength of the collagen fibrils. Would enjoy seeing a discussion of that by brothers who have used air and water pumps, .. probably though in its own thread.]
