Scenes, playing, dear old friends, kink community.....this is all so much part of the script, the narrative, the circumscribed way in which one is meant to live if they are wired up this way. I've met quite a few people who talk the talk. I've read in so many places that "the sub has the power", we have safe words, we are "sane, safe and consensual" it becomes scripted just like their scenes. Its a world with different language, and different rules, "immoral relationship models" and it's all a bit pretentious. It's about subscribing not subverting anything. This allows a lot of wannabe Doms to mascarade about the place.
I don't know whether you are a Dom, I only know you profess to be. I've seen the self professed tie themselves in knots, but I'm not sure if I one hundred percent agree with Yorick whilst as a generalisation more experienced Doms have very good emotional regulation, and tend to be more contained. One has to master themselves before they can be master over anyone else.
This is where it gets complicated. The scene is hellbent on using language to set up certain rules. One should establish boundaries and rules, and these should be consensual, and the sub has the power, you are simply playing at being her dominant. Well, that might work with play dates but outside of that it's far less subscribed and a whole lot more nuanced. I don't subscribe to this nonsense. A Dominant is a dominant and it's in his DNA to use his intellect, and his emotional intelligence to read off a sub, to understand her, to want to really dominate her mind, body and soul, to direct her, to inspire her unwavering loyalty, to put him above others, and to care for her. In order to meet her need to submit, he must allow her to do so, and it's meaningless if that submission is dependent upon her willingness. For it to be logical, for it to be meaningful then the dominant would have to be demanding this basic thing. You can't otherwise square this circle! That's why it's all a lot of nonsense to "play" Could a true sub submit to playing at being submissive to a man who is playing at being a dominant? I couldn't.
I don't play, never have. How could one trust someone they barely know. Which brings us back to this fundamental question of whether you really know this woman. You don't yet. And whilst you're playing at this silly totally constructed, totally stereotypical "kink" lifestyle choice, bringing in a lot of limitations, bringing in other people, avoiding getting to know the real person, you might never know! And in no meaningful way will you ever be her dominant.
If I were you, if you really do like this woman, get to know her, take your time, cut out all the bullshit stereotypical (it's a bit boring) crap, dispense with the old friends, and be really authentically open to a relationship that might develop. Might. Allow yourselves to be authentically yourselves not based on some silly paradoxical stereotype of a "kink" or Ds relationship.
