I've been thinking about how to do this since the Power Assist isn't available at this time and I am confident this will provide an intense stretch and still let you perform some of the PA exercises. What you need to do is go to the pet store and buy a double looped cotton rope tug toy for dogs. Then hang one end of it over a door knob. Then put your penis through the the other loop, grip , and squat to perform the stretch . I think this would have great potential for maximum stretch since you would be using your body weight to apply the force and you would still be able to stretch in multiple directions. This is a close second to the Power Assist but I think it would work well until the PA's are available again.
