nkf, hellllllll no. The last argument DP and I had (excluding the ones where I was being an arse, I'm fallible and still have bad habits to lose) was about her not using the safeword when she bloody well ought to have - not just in my judgment, but objectively.
She's now occasionally moaning about sessions cut short, but I - and any other self-respecting top - would rather put up with a bit of earache for stopping short than get it wrong the other way.
And I got a bit of a (mild, she got the point) moan recently for not doing X when she plainly wanted it, but she hadn't raised it beforehand and I wasn't going to take her 'Oooooh yes' at face value when she was elated and emotionally flying after what I'd just done to her.
Destinysdaughter, my experience is that control is shared much like between the lead and follow in a partner dance. The lead (dominant) is providing the energy on which the follow (submissive) is moving. Both with a role to play, each useless without the other, and in constant and close communication to make the dance as a whole work. And, of course, either can walk off the dancefloor at any time if the other gets it wrong. The submissive needs a safeword where a dancer doesn't because, well, stopping takes cooperation in a fetish session whereas either dancer can just ... stop.
And DAMN if this isn't a thread that's a long way from where it started.
