Ligaments to tough for length gains

Hi guys, first post so be gentle! Basically I purely want to increase the length of my penis (for now, girth later as its currently a respectable 6.25ish) but I feel like where my dick is ‘attached’ there is absolutely no stretch what so ever, feels like the penis is attached by a metal chain rather than a rubber band! Any help would be greatly appreciated, concerning as I now feel like there’s hope of achieving a longer penis after reading some posts on the forum

Size matters ~

Are you saying your ligaments are too tough for gains because you tried and had no results? Or are you assuming they are because you haven’t tried yet? I wore braces on my teeth for a few years and completely moved every tooth in my mouth. If my jaw bones are elastic enough for that, your penis might be somewhat capable of stretching, appearances aside.
