I get that it will not be a universal kink. I can tell you there is a big difference between sounds and catheters and also a big difference between a domme doing it and doing it yourself. I respect that you have a limit. Kink is a vast playing field.

Perhaps someone can explain it to both of us. I know safety techniques (of course), and certain things garner positive reactions, but I am clueless as to how it actually feels.
