That old 'psychology' is sometimes inexplicable .... to be sure !
I have another post about the psychology of tickling, how our brain is wired differently for different things...some is pure physical nerve tracts in the brain..some is 'learned' or adaptive behavior from our experiences ...
That mind melting love/hate sensation with tickling ...being tickled can for some be a powerful desire, need, craving......And I've delivered that sensation as a tickler to play partners ... all without any sexual connotations at all...I am in that category of having a tickling 'fixation'..
Some HAVE to have tickling as part of their sexual satisfaction (the true fetishists or kinksters, I guess 😊)....
neither is wrong or right per se...its all what we want or become accustomed to...
The love/hate sensations with BEING tickled is very similar to sensual edging....prolonged overwhelming sensations that we seek to find a definitive ending ......and our minds / brains can't separate the two in some cases...
The Lee does want it to end eventually...for the endorphin bath after the exciting adrenaline rush during the tickling...Same situation with sensual pleasures....
That connection though is why you can, with care and respect, sometimes introduce someone to the tickling fixation, and 'guide' them into exploring that side of their personality...
