It may be pointless, but I'll give it one more try. I'm having trouble explaining what I mean so that it's comprehensible.
I'm the one, way upthread, who said sex is about feeling good, and that respect is a separate issue. There were several responses that the one without the other isn't worth having, and if you can only get one, respect is better.
I'm not disputing that. What I'm trying to say is that sex, as a category, by itself, as a biological action, involves nerves that give you a high. The many other nerves inside your brain that recognize being treated as a full and significant member of your group, aka respect, is a different matter.
That's not saying the two aren't much better together. What I'm trying to say is that the current porn-soaked understanding of sex is so far away from sex that you could mix in as much respect as you wanted and it still would not result in good sex.
The porn-soaked view is that sex is just a tool for performing male dominance. Yes, the marker of "winning" is ejaculating, but the point is the dominance, not enjoyment. If it was enjoyment, violence and humiliation would not be essential. Every now and again, at least, porn would equal what used to be called erotica instead of being an endless parade of violated women.
If sex is misunderstood as dominance (and therefore necessarily somebody else's submission), then it might seem like respect would help, since respect is partly about tamping down oneupsmanship. But, if sex is misunderstood as dominance, it can never be sex in the feel-good sense. Respect isn't going to end in highs, no matter how heartfelt it becomes.
Think of it in an analogy with jokes and laughter. You're with a group of friends, getting funnier and funnier until you're all laughing so much your sides ache. That's never going to happen at the company Christmas party with your boss on one side and the company president on the other. Everybody can even respect each other, but the social dynamics are too overwhelming to allow pure enjoyment to just go for it. And, obviously, if the boss is a jerk who uses the time to dump on subordinates, it's just that much worse.
Also, obviously, in the group of friends there's all the respect and kindness necessary to treat each other as equals. Otherwise enjoyment can't even get started. But respect is just a mere pre-condition. If it's not there, the whole thing fails. But it's not what makes the jokes funny or has you laughing.
