"What would you suggest he create man with that would be useless enough to cut off to show they're set apart from anyone else?"
tuff question, good question. To show they're (we're) set apart from anyone else...
--surgical removal of only the tip for easier retraction (good for phimosis, too)
--a medial incision in the frenulum so it doesn't act as a tether and possiblely hurt when stretched. (similar to a frenulectomy)
--"attenuate" sensory nerves with microsurgery and minimal loss of tissue (i think it can be done:-^ )
