can anyone tell me about flagellation/masochism as a mystical practice? how prevalent is it outside christianity? does it work differently if you're the type of person that derives pleasure from the physical sensation of pain as opposed to doing it as penance? any books on the subject? is the original hellraiser a good movie, I've heard mixed things?
I vaguely remember hearing something bout aztec rituals involving putting a barbed string through your foreskin but I don't know what the source on that was.
