The guy who killed John Wilkes Booth cut off his penis so he wouldn't be tempted to screw prostitutes.
"On July 16, 1858, in order to avoid the temptation of prostitutes, Corbett castrated himself with a pair of scissors. Afterward, he ate a meal and went to a prayer meeting, before going for medical treatment."
I don't know what to tell you, some people are just retarded.
