First, let me say I do not know about the veracity of any of this. My comments on length vs girth were simply what I perceive as common sense.
To break this down in the simplest terms, there are a couple of points you have to look at.
First, does all length come strictly from lig stretch or growth, or does length also come from tunica stretch or growth. In my experience, at least half of my length came from tunica stretch or growth, going by the amount I gained to, and then past my navel. The increase in lig stretch should not have affected this measure very much.
That leads to two other questions:
If indeed length comes from tunica stretch or growth, then is there any difference in the ease or amount of gains possible from differing tunica’; the amount of collagen material to be found in differing penis of varying girths?
Then, when doing girth exercises, does the tunica stretch or grow laterally?
Since the tunica is the limiting factor in girth, provided there is sufficient blood flow, it is obvious the tunica does stretch or grow. Which is it? If it only stretched, then it should become weaker. Since there are no reports of torn or ripped tunica, it would seem that it probably grows, with new material filling in as it becomes larger to handle a larger girth, and subsequently remaining at the same strength laterally or possibly stronger. That is my experience. Mine actually has more material.
So, if girth gains do provide more material, is that material as strong, or stronger than the original girth. Beats me, but I would tend to think it is stronger. Much stronger. So, would length gains be harder or easier considering this new material, attempting to stretch it lengthwise. IMO, yes.
On another related note, starting from scratch, do thin guys or thick guys have more trouble gaining length. I have no concrete data, and there is anecdotal evidence either way. But in general, over the years, it seems to me that guys who start thin have a much easier time gaining length, than guys who started thick. All I can say is it is a strong general impression.
For what it is worth,
