Triple cock ring

[daddys_toy]

Both us are quite a bit fascinated by this...

Problem is that neither one of us is sure what size to get for him. How do you measure for something like this? The solid cock rings that we have already... we have difficulty slipping the balls into the ring, to the point, Daddy says, that they feel like the're being squeezed. Not, i might add, in any way that's comfy or pleasing for him.

Any suggestions on measuring or method of putting on the rings?

thanks!

They give directions to sizes below. Not quite sure what your uncertainty is about. Says large if you usually use a cock ring 2" in diameter and medium of you usually use one 1.75". So measure his cock around its girth to see. Am I missing something?
