Anyway. I think an understated component of the art of submission is mid-scene communication.
I don't mean safewords or expressions of consent or whatever, as important as they may be. I mean the subtler stuff. The little noises and movements, the stimming and staring, the touching and grabbing. How do you communicate your desires? How do you communicate your needs? How do you communicate your enjoyment?
With one partner of mine, I think my favorite thing ever is when it starts hitting the bed beside it out of frustrated arousal. I've seen three subs now that have conditioned themselves to sort of tie their wrists together in mental bondage when they're really down bad and it makes every dom that's seen it go crazy. I've seen subs that drool and stare and subs that just start desperately grabbing and fighting. I've known subs to go nonverbal and make unnoises and even seen subs that start crying. Of course, there's even just watching your word choice simplify or hearing you struggle to speak.
In every case, the most important part, to me, is that something happens and that it's visible and measurable for the dom. Clear, explicit feedback doesn't need to be words. It doesn't need to look like how someone else looks. It should, I think, look like you. And if yours is weird enough, you shouldn't try to change it, you just at most just tell your dom about it. But I think the most important part is that you let it out and that it's impulsive and genuine and from the heart.
Generally, it's hard for a lot of subs to fully "let go" and just start making noises. Of course it's partially your dom's job to help you get there. But I think it's a skill that can be practiced and something you can actively work on even outside of scenes.
