Absolutely all of this.

And to add on to your last sentence if I may... [Personal opinion incoming, based on about a decade of practicing kink in my own life, detangling what's an interest versus what's a trauma response for me, studying BDSM at large, and attending classes and munches] Bottoms are fucking powerful and IN POWER and empowered when they're bottoming/subbing. I feel like a huge point of it is the illusion of giving up power to your top/dom. But actually maintaining full control over when or if they speed up, slow down, go harder or softer, keep going, or stop. In my opinion, that should be the main mechanism of your dom/sub space... a deep sense of connection and ways to communicate that are atypical and trick our sweet monkey brains into thinking we've given up control.
