Does anybody NOT get trembling/quaking/shaking

This always confused me, i never get this or rather i get them very, very infrequently, doenst seem to be ant reflection on the intensity of the orgasm either, no correlation at all. Anyone?

I may have had this once or twice a year or two ago.
Never had an orgasm though.
Not sure what it means, perhaps it's like a nervous twitch like when your eyelid twitches - I thought I read somewhere that it's a sign of some neurological condition or stress...

I've had them only a handful of times, usually it's one of my legs flailing suddenly, but it happens once then it's gone.
I've never had sustained high magnitude (and completely involuntary) shaking, but in a way I can see how it could be possible. The full-body uncontrollable flailing is probably one of the things I've found hardest to believe about super-o experiences, but if what I felt in my leg could repeat over and over, and move to other parts of my body, then that's probably what I'd look like.

I get them violently. Almost like seizures. I've had to learn to control them because I was throwing my back out.

I have them once in a while. These seem to generate from certain sensitive spots when they are stimulated repeatedly. Some have been VERY wild too.
