What exactly is the science behind bundling/twisting? I came across these stretches a while back but I never did them thinking they would deform my cock in some way but I finally came around and started doing them. I just wanted to know why are they good and how do they not deform the penis, because it really seems like they would. I wasn't sure where to ask this question but I figure since the [words=http://www.mattersofsize.com/forum/showthread.php?83577-Length-master-official-order-thread-now-shipping-06-16-2014!!!]lengthmaster[/words] provides the best bundling experience I would post it here.
