Like I associate tickling with weakness almost, which is not a complaint.
This is exactly where my mentality's at and where it's always been. I'm incapable of conceiving of ticklishness as anything but a weakness, and consequently as a very ticklish person the potential of getting tickled by someone else is extremely humbling. What's strong, after all, about curling up and retreating when someone touched your sides or abdomen, or about having someone else assume complete control (with or without your permission) over whether and how hard you laugh, and whether and how vigorously your body squirms?
That absence of strength, that abdication of power, that frisson of humiliation -- and my utter lack of authority over whether someone takes advantage of it or not -- has always been a big ingredient of what I find gratifying (and maddening) about it, and my socially ingrained, involuntary assumptions about gender dynamics (men strong, women weak -- except when they decide to tickle me) play a big role in that.
