Of course it is paradox if you manage to view it once from outside of your system of rules. You didn't get my point: From the outside (and let me tell you, for this perception expertise plays no role, but common sense does) BDSM, a sub/dom relationship promises giving up control, risking something leaving your boring secure normality - if you accept it or not, this is how people view it, this is its appeal. For me personally there would be no other reason even to think about doing it if i would think about it. Whereas a normal relationship is supposed to be about trust and love and safety. This is simple common sense. The paradox is, that in reality it seems the other way around if we follow these rules you talk about. Normal relationships have no contracts, no safewords. You are constructing a safe space which doesn't exist for normal relationships. The trust you claim you have in BDSM secured, you can only hope for in normal relationship, but you can't rely on it, we see it daily. Everything depends upon emotions. You have nothing under control in normal relationships. Everyday your spouse can come home and say it's over. You can't even rely on her being in the mood for sex - which you can be sure you get in one form or the other (even denial is a sexual act) within BDSM. So don't tell me it isn't paradox. The trust you have to have in your partner is totally unregulated, uncontrolled and way more risky, with real life consequences. And in that sense, this could be more entertaining to view than a well regulated BDSM relationship. Any cuck, to take my NTS example, has surrendered himself more to his girlfriend than any sub in the BDSM you describe. She can destroy him tomorrow.
And I intended to let it go earlier, but because you again claim that I want slavery: Of course not. Firstly I talk about what I want to watch not what I want in real life. And, second, you confuse risk with slavery. Of course Cindy in this case could ALWAYS leave again if it is too much. So it's not slavery in this sense. It is subordination. If you youse constantly the word submission you have to give it a meaning. It is following orders. You shouldn't have to get to choose anymore, you shouldn't have to get to say no. But of course you have an exit option as always in modern societies. But for that you would have to break off the whole relationship. and guess what? That's the same with normal relationships: you get to a point where you have to be prepared to leave completely. This is what I would find more exciting for Cindy: she would have to go all in, and if she can't stand it in the end, she would have to leave the firm. End of it. Then you would have stakes at play, not if she could say no if she thinks a slap hurted too much or if she is not in the mood that evening.
