Hi all,
Last night I experienced something I have never read or heard about while having a SB session. I had put a pump gag on with a head harness over it and was doing an improv session. Nothing strict mind you was able to adjust and release at any time. The phenomenon occurred when I found myself able to breathe in but not exhale. A most strange feeling I have to admit. I removed the head harness and gag and my muscles relaxed and everything returned to normal.
I guess, as I had never experienced this or even heard of it before, I should put it out before the community so others can identify what exactly it was I experienced, and to make others aware.
