Oh, I'm so glad you bumped this thread, his_j! Because I gained a moment of insight this morning, when talking to another French dom (i.e. not mine, but known to us both). I'll have to paraphrase the beginning, to save translating the whole conversation, lol.

Me - I'd like to be able to react like that, I mean - and to stay, I don't know, conscious - in control - to be able to react and not simply be led by the emotions of the moment.
Him - I think it is not only about emotions, it works sometimes through a true uncoupling (or disengagement) from reality. A total abandonment takes place
Me - Yes... I don't know if I manage that either - maybe sometimes - certainly, one leaves to one side the constraints of logic
Him - You talk that way, no doubt, because you are not very advanced on this path of submission, but it will come. Perhaps you still wish to retain a certain control over the other
Me - Over the other... No, over myself, I think, above all
Him - Certainly, but that implies domination of the other
Me - Oh!
Me - I'm going to have to think about that
Him - lol - yes, think about it carefully. Because the swing happens at precisely this point

I hope the translation works so that you can see - and appreciate - the moment that made me go 'Oh!'. I'd just never thought of it that way.
