for the people who want to knee jerk and say "but I am! im built different!!" I cant tell you the number of times ive been in a scene where I discussed what I wanted to do before hand and the sub was into it, but changed their mind mid scene, and didnt tell me until afterwards.
trying to teach the "no limits" sub that its actually bad to not establish boundaries and that you don't actually want me to do whatever I want with you. I promise you're not actually into "whatever you are".
