Dog, I was hoping you’d save me the effort…but here goes.
Any soft thing will do, the idea is to not have any hard edges that can cause any injury to blood vessels or nerves or any tissue.
Soft distributes the forces evenly and comfortably.
I found that a 1/2 inch wide x 12 inch long piece of t-shirt material works great, I like the sewn edge from the bottom best, its folded and sewn so its stronger.
The idea is to experiment with different levels of snug and observe what level of erection it produces.
The main idea is to maintain circulation while maintaining a level of erection that you decide and can do.
By maintaining circulation, I mean keeping normal or near normal color and temp.
So lets just say you want to maintain about 50% erection for 2 hours.
I recommend getting a partial erection if you can, then tie it snug, just a little smaller than your girth and wait and see what happens.
If its too tight, you will get harder, if too loose…softer.
Lets just say you nail it, but as a half hour goes by you start to get bigger, which in turn makes it snugger which leads to a very hard erection….then you would have to loosen it to bring it down a bit…get it?
Its really not difficult, it just takes some experimentation.
As with any constriction, do not sleep with it on, or walk around with it in your pants without supervision until you really get the hang of it.
You don’t want to go to work or bed, not look at it for 6 hours, then drop your pants to find a black dead dick because you weren’t paying attention…right?
So take the time to learn it, and I think this will be very productive for girth!
