cruxbound
Assistant executioner
I think it would only have worked with convicts who were strongly masochistic (in the sense of pain causing arousal). In all other cases the pain and discomfort associated with real crucifixion in roman style were too strong to allow for any sexual stimulation to be effective. Things become a different matter in case of staged crucifixions in a BDSM setting of course when the level of pain can be reduced according to the desires of the "convict" in order to make way for a regime where he or she is more (even highly) receptive to arousal and orgasm.
