An interesting question. I’m sure social scientists have precise definitions and language to identify personality types.
Certainly tickling can have various degrees of the D/s and BDSM.
I’ve played with lees who embraced and enjoyed being tickled. For me, the most satisfying has been with lees who are truly, insanely ticklish, but can get turned on being tickled. That may come close to masochistic behavior as well as some sadistic behavior for the Ler. The ordeal of being mercilessly tickled can result in satisfying pleasure.
Some get off on masochistic play. Many don’t. Particularly in this time where women , as well as some men, have brought attention to misogynistic, chauvinistic behavior that is unacceptable.
If there is full consent and agreement beforehand, exploring dominance and submission with tickling as a primary part of it can be amazing.
