I got a kit with a few ring sizes and I am completely lost on which one is correct. One feels secure but leaves a bit of a mark after a couple of hours, the next size up feels like it might slip off.
How snug is too snug? I know a mark that fades is probably fine and numbness or any colour change is a hard stop, but everything in between is confusing me. How did you settle on your size without just guessing?
