I agree, for a metal ring it is very important that you have the proper size. From another web site, they recommend this for sizing.
"To calculate the minimum size of a cock ring, cut a strip of paper or ribbon no wider than 1/4 inch. Starting from the top of your penis at the base (where it meets your body), wrap the paper under your scrotum, bringing it around to the starting point. Mark the paper where it meets. Measure that length, then divide by three.
The correct diameter of the cock ring you should order is approximately one-third of the length."
I did this for my first cock ring, which was a gear essential one, and it fit well.
