I have only freaked out (panic attack) during a session twice and in both cases it involved a triple combination of tight restraint, heavy corporal and a blindfold. It is not an experience i want to have again so I have made Dommes aware of that since the last incident. I have no problems otherwise with being blindfolded for part of a session. On occasion it has been a slight enhancement.

As to why Dommes use blindfolds my experience that for the most part it is a change of pace, a way to give a segment of a session a different flavor. As for Asp's theory that it gives them an opportunity to slip out of uncomfortable outfits, that might be true in some cases but I've been blindfolded during sessions when they were wearing street clothes (as I've aged outfits have become less and less important to me)
