@NotBadConsidering you seem to be fundamentally misunderstanding how this works. I chose for that to happen, allowed him to do that. Took on any risk of the situation, which after having had it explained to me and me looking into it (and deciding I did not want to go through with a full choke out) I felt was negligible. When I felt I no longer wanted to continue, I said stop, and he did. Immediately.
I actually left it a few seconds, I could have tapped earlier but allowed it to continue, then decided no, I do want to stop. So we did. Simple.
There was no demonstrable harm done to me. If I’d passed out, there’d have been no harm, I’d just have come round again. We haven’t repeated it as no need or desire to, he showed me it, it clearly doesn’t work for me, so it stops there.
I have at no point encouraged anyone to do it, I’m talking about my own choices in my own life. Not saying copy me, not saying anyone else should do it. That’s their choice to make.
