How long will it take for a man to suffocate with a bag over the head like that? I am al;ways too scared to go alone for longer than maybe half a minute but would like to experience it with someone controlling the length of time.
When doing this with someone and the guy has reached the point of just passing out, how does one do a safe revival? I know at that point there is a slight danger of brain damage but if quick that is not significant.
