What involuntary things happen when you orgasm? Do you moan, shake, curl your toes, etc? NSFW

I once had a fully body organs that made my calves cramp lol

I usually moan and shake a bit depending on how hard I orgasm

i think there's like... different levels of involuntary. like, literally, could not stop? or would significantly hamper / impede the orgasm if they were stopped?

If it's a good orgasm I tend to moan and shake a little

I’ve lately been relaxing my entire body as much as possible when I feel an orgasm about to happen. Since I’ve been doing that, I SCREAM involuntarily when I orgasm. It’s so incredibly intense, and it makes my partner laugh.

Depending on how hard I orgasm, I usually moan and twitch.

I don't think I had a reaction that I can't control besides cumming and well, gasps. I have yet to see if that sort of stuff is true.

EDIT: Not sure if involuntary, but I def curl my toes and push as hard as possible.
