I agree with Thunder!
I have been lurking thru this thread for quite a while now and have nearly acquired all the materials to construct a stretcher exactly like yours (maybe a couple of tweaks - if they work i will keep you all informed)
I reckon this stretcher will be great for stretching but also maybe used in a much looser state for long periods after hanging or intense stretching to keep the penis stretched out whilst healing.
can’t do any harm. And like you say its a lot easier than sliding about with weights between your legs!
ps for anyone looking for those pipe hangers in the uk the only place i could source them was from RS Components.
