Hanging a man is to hold his body up to ridicule. In a short time, blood pools in the lower extremities- so his penis will sprout. Spinal imjuries produce an erection. Although the victim experiences pain and no sexual pleasure, I wonder if his reproductive fluids flow. The French Universal Dictionary of the 9th Century maintins he does (cum). But, I have read so many other accounts that say NO, he does not. I do not mean to include those men who are looking for auto-erotic stimulation and accidentally die, but as a simple body mechanism as if it is Nature's last desperate attempt to keep the race going, like flowers shedding their seeds in the wind. Forgive my romanticism.
