Ok, I see we have to go back to basic things:
"Tension Under Stretch
Elastic fibers are barely existent in human tendons, making up about 2% of a tendon's dry mass, and being mostly elastin. Elastin contributes primarily to the recovery of the wavy collagen fiber configuration after muscle contraction and tendon stretch. However, if elongation exceeds approximately 4% of its original length, minor damage to the tendon tissue could occur. "
4%+ elongation..does this remember us something?
"Moreover, acute stress resulting in an 8%+ elongation may cause tendon rupture. Injury to a tendon results in inflammation, edema, and pain. The consequence is tendinitis, tendinous bursitis, insertitis, peritendinitis, or any combination. If the damage progresses, without adequate recovery and proper rehabilitation, tendinosis, partial tears, and complete ruptures may ensue."
……..
"Cumulative Microtrauma
It is estimated that as much as half of sports injuries are due to overuse, with musculotendinous units being the most commonly affected. The cause of overuse injury is repetitive strain of the affected tendon so that the tendon is unable to remodel during recovery. Consequently, the tendon is unable to endure further stress, and its structure begins to fail, resulting in inflammation, edema, and pain."
……..
"Tendon Strains
A strain injury occurs when a tendon has been stretched and microscopically damaged, with macroscopic disruption of the tendon fiber bundles. Within four hours of a tendon strain, fibronectin and fibrin permeate the damaged area. Within 24 hours, there occurs inflammation with hemorrhage, edema, muscle cell necrosis, and proliferation of leukocytes. Tendon fibers also break down, with macrophage phagocytosis, and continued inflammation."

So, its quite clear to me that repetead stretching/hanging with high loads can cause some sort of damage; this damage can have different degrees; what is most common with repetead stretching is the "cumulative microtrauma". How you can exclude that microtrauma is produced after having hanged 3+ hours/day, 7/7?
If you have caused a trauma to your penis, an healing process start:
"Tendon healing process
Tendon healing can be largely divided into 3 overlapping phases, inflammatory repairing and remodelling phases:
The initial inflammatory phase, which lasts about 24 hours, erythrocytes, platelets and inflammatory cells (eg: neutrophils, monocytes and macrophages) migrate to the wound site and clean the site of necrotic materials by phagocytosis. In the meantime, these cells release phaso active and chemo tactic factors which recruit tendon fibroblast to begin collegan synthesis and deposition.
A few days after the injury, the repairing phase begins. In this phase, which lasts a few weeks, tendon fibroblast synthesise abundant collegan and other extra cellular matrix components such as proteoglycans and deposit them at the wound site.
After about 6 weeks, the remodelling phase starts. This phase is characterised by decreased cellularity and decreased collagen and glycosaminoglycan synthesis. During this period, the repair tissue changes to fibrous tissue, this again changes to scar like tendon tissue after 10 weeks. During the later remodelling phase covalent bonding between the collagen fibres increases resulting in repaired tissue with highest stiffness and tense our strength. Also, both the metabolism of tenocytes and tendon vascularity decline."

Those who are supposing that definitive elongation happens only by collagen rearrangement, without production of new cells, are leaving out a "piece" of the adaptation to stress of connective tissue.
Defenders of the "continuative work" thesis started supposing that healing happens while loading - at the same time.
When this thesis has shown to be hard to defend, they came supposing that healing is not needed at all.
But this is even harder.
We have seen that repeating the stretch many times has no real more benefits: after the first times, elongation does not augment; cumulative microtrauma are augmenting. Micro-tears, healing, fibroplasia, definitive elongation on the long run.
The "connective tissue elongation process" has been treated many times on this site.
Also, firegoat explained how this process likely happens, in a clear way: see the thread he linked here, and the link you can find there. And read.
Now, specifically to you, Dick Builder: I haven’t nothing against hanging. What I’m saying does apply to stretching, pumping, clamping etc. etc..
Micro-tears, that you are supposing are caused by repeated strethcing/hanging, call for a repairing process: yuo can call it "healing phase", "repairing phase" or whatever else.You can suppose that that phase requires 6 h, 12 h, 48 h or whatever you think is more likely.Things doesn’t changes.
Connective tissue is living tissue. Long-term alterations are a result of adaptation, not of simple mechanic deformations.
