47-1278 is right. Body dysmorphic disorder (BDD) is when you believe that there is something wrong with your own body. I called it dis-morphism earlier because of spell check, which is wrong. It is not listed as a mental disorder to want to change other people's bodies or at least it is not listed in the Diagnostic Manual 5 (DM-V). Removing a man's penis will partially reduce his sex drive. This would affect people on an individual basis. Everyone reacts different to change. A man can have sex without his testicles. Erections are still possible and the prostate still works meaning that he can still cum. He cannot have sex without his penis.
