But wouldn’t that apply also to longitudinal stretch? This would mean using an extender for 2 times 10 minutes makes more sense then hours continuously, which worked for many.
Not necessarily. The research was done on lab produced molecules if my interpretation is correct, which could mean different behavior from human tissue, yes, but remember that a ligament is far less elastic than the tunica, which can inflate to several times it’s relaxed size during an erection. The collagen and elastin makeup of connective tissue would be much different. It’s also quite possible that hanging or stretching is subject to the same phenomenon, but on a completely different time scale. What if the optimal stretch time is multiple hours per day? Naturally no one would have crossed that threshold in their routine since stretching is severely limited by other factors, such as de-oxygenation and so on.
I’ll repeat what I said earlier, we ‘re not only working on collagen, nor are we solely working on the tunica.
You’re absolutely right, but I think we can agree that the tunica is most likely the limiting factor. As far as girth is concerned, everything else involved in an erection is even more elastic, skin, blood vessels, fascia.. They may be stretched taught when clamped, but nothing is resisting the expansion more than the tunica.
