This is sort of an obligatory fitting / sizing post. I have read other CB-6000 sizing posts, but I'm still not 100% sure. Sorry to clutter up the forum with more of this (perhaps a sticky could be made with a compilation of info editing and updated to the first post, where people can most more questions? I don't know.) Anyways. I use ring 1. I've gotten kinda fed up with how far it can slide down my balls. Occasionally there is some discomfort there, as I think one of the testes partially gets caught under the ring. I don't know, sorta hard to describe. Anyways, I just tried ring 2 out and after 20 mins there was some partial discoloration that appeared. It wasn't all that bad, but it didn't seem like my normal color. So I switched back to ring 1. But I'm wondering if you have any advice here? I guess 2 is just slightly too small? But it does give a firmer fit around my balls... darn. What's a guy to do?
