Haven’t the time to read all of the posts but I figured I’d add a bit of my own data to the discussion. My erections are amazing. 11 on a scale of 1 to 10. I just turned 42. I get raging wood every time I sleep, even if it’s just a nap. If anyone is following my thread about Puerto Rican women, they will see that, after my necking session with J, it took around 20 minutes for my erection to go away, without any type of stimulation, at all. It was rock hard for pretty much the entire 20 minutyes, then it just went down.
I smoke a pipe and cigars, by the way, and that has never seemed to hurt my erectons at all. I do fuck and masturbate at a frequency level that most would consider extreme.
When I do PE, which isn’t very consistent with me, I find that my girth increased, at the base, with hanging, but I never got much gains, at all, from any of the girth exercises. My total PE experience has been that, except for the base girth gains, I only maximized what I had when I was in my teens. When I jelq, I always do it at full erection. I have never been able to achieve a partial erection to jelq at that level. It’s either rock hard or it’s not hard. If I get excited to partial erection, the minute I start jelqing, it goes full monty. To round out the info, I do not have a refractory period. I have never seen any erection quality difference beteen morning wood, masturbation, or sex.
From what I read at the beginning of this thread, I’d say that my PE experience supports this theory. My smooth muscle must be bumping, as modern parlance would have it, and it must be that I need to do length exercises to increase the tunica, which is supported by my base girth gains from hanging.
