The related videos feature some sort of medieval torture rack for your wiener, in case that looks like a good idea to anyone who can't stand being in the 85-90% of guys that are within an inch of average.
I have to wonder if it's really possible that none of these things work. I mean, there's those ladies with the crazy long necks. Couldn't you just put a bunch of brass rings on some dude's dick? They literally already sell penis sized brass rings.
I'm not an expert on dick mechanics, but let's say you were able to stretch your member out another few inches. Woulnd't you need to be able to pump more blood to make that sucker hard? I always imagined Jonah Falcon, at best, could sport a semi.
I imagine it might be possible, but you'd sacrifice girth for length. There is nothing ok about a very long skinny dick. None of the joy, all of the cervix bashing pain.
