Flat cage makes quite a difference.I agree with Funcouple555 above. After 20 years of 24/7/365 caging with progressively smaller cages, and the ageing process itself, mine is 3/4 inch as you can see in the picture below in the open cock cage.

For various reasons, primarily touching myself through the cage, the Wife put me in a more restrictive and smaller yet cage. There is virtually no length to it's shaft and my balls protrude further than my shaft.
