That’s great info pud, thanks.
When I compared to a wetsuit, I wasn’t referring to the actual structure, just the idea of how it can seem really tight, for example around your arm, but if you flex, it still stretches.
What I am wondering about is how the drawing you posted translates into 3 dimensions. In other words, how pulling longitudinally effects the fiber orientation in the radial direction, or visa versa.
Also, I wonder how that structure is modified from PE induced growth. I have heard the theory in the past, that breaking the elastin fibers causes a gain in flaccid size by allowing the unfolding, but what exactly needs to happen to cause erect gains?
