Unfortuntely for me (but fortunate for the few that ever capture me as a victim) I am horrendously ticklish on my feet, but little anywhere else.
This is why I can dish it out so well and make the bondage contraptions that I do: I simply dream up what would be the worst thing I myself would never want to endure, and then design it... and get someone else in it.
There is no unified and honest code for judging how GENUINELY ticklish people are in the so-called "tickling community" however. I've found over the many years that the majority (not everyone) of them who are "into it" and "love it" are usually not really ticklish at all (not by any standards I myself would call ticklish)... and they more or less fake and embellish it in order to fullfill whatever it is that excites them about it. But more power to'em!
Everyone over uses the word "I'm excruciatingly ticklish", or, "on a scale of one to ten I'm a 12!"- if they really were, they wouldn't be "into it" unless they enjoy the panic of it (one of the thrills I find about it). And I've seen those use the phrase "insanely ticklish" who were not the least bit ticklish, and faking it badly at that. More "dead fish" as my close friends call it.
There's always exceptions to the above rule... and God how I love those exceptions!
