Thanks for your answers Flaming_Redhead.

A few questions regarding that please?

It's more like fear of being severely wounded and/or dying.
So, the doubt whether your Dominant/Top will in fact keep you safe? Or might this time decide to push you beyond your limits, or might not be able to keep you safe?


Would you say you experience the fear most acutely before or during the edge play?

You mention subspace and it makes sense to feel that after a time in the scene... and after. But does this mean you don't have any Other physical reaction to the fear beforehand?
When i am preparing myself for a scene that I know will include pain, I experience the most fear before the scene and way less during... almost like when I submit to whatever He had planned for me, the actual feelings of fear (heart pounding, shallow breath etcetc) disappear.
