8x61/2
Congrats, Juggernaut, as this means you can beat the "dollar bill challenge". Some men use that as a test of ultimate girth, since a U.S. Dollar bill is 6.14 inches long.
what kind of size I'm after
I believe your length gains may have maxed out unless you find a creative way to stretch the tunica albuginea. The tunica is at least 90% collagen, which stubbornly retains its structure. At least the remaining percentage is not a barrier since it is malleable tissue such as elastin. But it is that darn collagen in the tunica creating a hard limit. Ironic, since collagen is mostly thought of as a good thing on beauty forums (which it is, in terms of keeping a face looking young).
At one time I read penis-enhancement forums, and some of the frontiers in chemical PE involved finding the perfect collagenase to break down the collagen, and if that can be found, a perfect delivery system is needed (possibly topically using DMSO as a transport). I don't think anyone succeeded. After all, you don't want to break down all of the peptide bonds holding the penile structure in place, or else your junk would just devolve into a melted lump.
Once I realized I could not break the hard limit set by the tunica, I gave up traditional penis enlargement. I already had 7 inches anyway, so by most any woman's standard that is plenty enough to do the job. I now focus on overall health, keeping the cardiac system healthy by avoiding refined carbohydrates and staying off the glucose-insulin rollercoaster that ravages the endothelial component of our vascular health. So I have a happy penis, but nothing that would intimidate a monster-cock owner.
