discussing kinky dynamics
one thing that pairs quite bad with not considering this is this common situation of struggling to express one's needs and not wanting to annoy anyone with them.because one might come to the conclusion of "oh, I don't want to annoy (playmate) having them do stuff I desire, I better just avoid asking for it"
when maybe that being would love beating you up, or leashing you, or putting you in diapers, or whatever it is you want, and you end up removing one opportunity for both of you to enjoy it together. and of course, that other being is also responsible for expressing themselves if they want that something... but they can't always be the ones to be doing all the work.
