I absolutely agree with your statements. It's funny because I had already drawn some of these conclusions awhile back. Even to the point of switching entirely from my girth. Girth is what I want and am most concerned with gaining. I have managed to gain 1/4" with a heavy girth routine in 1 yrs. time. I incidentally gained 1/4" length as well, but those are including newbie gains. I really didn't get much of any newbie gains. When I look at the long term I can't complain, but I wanted to speed up the process. This got me thinking of why I can't seem to gain very fast. Why can't I get my dick to expand? It's like a rock, especially when I am 100% hard. I mean if I hard kegal and squeeze at 100% I will gain 0. However if I am at 90% I get 1/4" expansion. So I started looking at my tunica being my limiting factor, because I thought of the bycicle tube and tire idea. Now as we know as far as documented medical studies, the tunica has 2 layers, and like you said running latitudinaly, and one longitudinally. So
my deduction was, they should be targeted separately. So I began hanging about a month and a half ago because my theory was (is) that if I stretch the first layer or longitudinal fibers. That would thin out and weaken the tunica, thereby making it easier to gain girth. I can then work the 2nd layer or latitudinal fibers easier and will be able to gain quicker and easier in the long term. That is why I find this thread so interesting that this pops up at this time, as it confirms many of my original thoughts and theory's. Obviously I believe in it, I'm betting on it after all, I am "hanging" here for girth as I type this.
