Edging is a about much more than just erection strength and staying power. Edging, when done correctly, will stretch the very dense tunica. Ballooning, similarly serves the same function. For the exercise(s) to be effective on a tunica stretching level one needs to hold the erection for some time. This is vital to tunica stretching in a similar way the
SizeGenetics works. They are very similar in the way a low tension stretch, for long periods, allow for the cementing process to happen much quicker. Gaining temporary girth is very easy, some guys using the
Bathmate see an inch of temporary gains after their session, I see a half inch after a good
Slow Squash Jelq session, I am sure you have seen other ways yourself at how easy gaining temporary girth is. Making it stick is the main objective. Cementing, as it's called, girth can be understood through how someone with priapism can end up with megaphalus. If an erection is held, at maximum hardness, for an extended time the penis will become larger. So, if you gain a half inch in girth after a good session, proceeding with long periods of edging would mimic the lengthly erections of priapism and this is just what the tunica needs, long, low tension expansion. When we start to add squeezing into the mix we start looking like a normal Penis Enlargement exercise, the difference, of course, would be the length of time you hold a full erection for. For a deeper look at this see:

Some black men suffer from a condition called Sickle Cell Anemia, along with a host of other symptoms, priapism is one. Due to this many black men have larger penis's then they would have if they did not have the condition. Some become what is called megaphallus, where the penis is grossly disfigured while others may only notice a slight enlargement. The point is, men who have chronic priapism largely have larger than usual penis's. I strongly believe that Shane Diesel has this disorder. (see picture)
Edging serves so many purposes and it is smart to get creative with it and plan to invest some time. I have a great routine that I was doing a couple years ago and they are definetly worth checking out:
