Lostracco, basing on your last pic, penis isn’t pulled out: it’s growing. Deforming in the proper meaning is something that does apply to not living things; living tissue isn’t normally deformed: it adapts to a stress.
The tissue is in a certain way damaged by a stressor agent, and react to that stress changing his structure.
So, yes, the mechanism isn’t so different from what happens in muscles trained lifting weights. Sure, you want to make your penis longer, not stronger; but the inner penis is made in a way that mother nature prevent it coming out - so, very near the base, it react to the stress becoming girthier - I think this makes sense.
Speaking in specific about connective tissue, there is a kind of ‘deformation’, due to the viscoelastic properties of that kind of tissue, but it isn’t permanent - I don’t think you are speaking of this kind of deformation, right?
Have you ever heard someone saying ‘Hey, my bulb popped out!’; even Bib, who claimed several inches of gains by hanging, never said such a thing - and believe me, if your bulb were going out of your body, you would be aware of that.
About ligs, they only attach the penis to your body, so they can’t add girth to your penis. But if ligs were pulled out of your penis, your dong would have a really weird look :) .
I also never had that feeling of light aching in the inner part of penis, signs of lenght gains : the most aching points of penis, when doing long time stretching/hanging, is at the base and near the midshaft of the penis - and those are the ‘zones’ that elongate the most as consequence of hanging.
I might add this: I did hanging with a device that avoided skin-growth (I am uncut); I have a mark on the skin at about 1” from the base. Despite the gains in length, that mark is always at that point: 1” from the base.
