So I've been trying this random technique where I grip the head with the left palm of my hand so that it pumps the blood out of the head and back down the shaft. And use the other hand to help pump that left palm hand up and down so that blood is pumped back and forth.. when I stop I can feel actual expansion that I dont feel from jelqs. Or uli.

I haven't kept and permanent gains yet but I'm going to do It everyday.
