Okay, let me put it in perspective for you. Toughening your penis happens. Happens to any of us when the device or exercises we are using stop working. That’s the nature of the beast. Enough time off and it’ll be fine. You haven’t caused damage to the penis. You’ve made the penis angry and defensive so it will fight all your PE attempts for the time being. Because your penis, like most of ours, doesn’t like to be tugged, squeezed, inflated or compressed. So after your tissue is done resisting all of what it feels like is torture…you’ll be able to find some method that works best for you.
Patience and being thorough with your logging and easing into each device and exercise is what you need to do. That way you can be sure what works, how much of it works for you and how often you need to do it.
There are guys here who have hung more than 30 lbs, who have used compression devices, I myself have done clamping with 4 clamps at a time and erect bends. An exercise I do not recommend unless you have ample experience with clamping, bending and understanding your penis and its PIs. But my penis is not extremely tough and after a couple of months I’m able to start anew with other things.
