Mark - I am not the pe-authority. Just trying to figure out how things are functioning.
You got my idea - a grower must have a lot of elastin in his dick which makes it difficult to get more flaccid. I think you should try wearing an ads or pe-weights. Ultimately we must all accept our genetic condition.
Did you improve your erect length?
I started at around 6” BP, may be some more when I was 25 at 0% fat on lower abdomen, and now after 2 years of stretching I am 8” BP and 7+” NBP.
I do stretching, never hanging, I love it. At the present my stretching routine lasts 50 minutes 3-5 times a week.
The problem with ADS is that, after my sessions of stretching for lenght and pumping-squeezes for girth , my penis NEED to rest, and I noticed that a Penimaster-like or a wrap have a turtling effect.
In other words my FL is growing but very slowly.
