I spent time in Africa and this note by Reuters sounds true to me.
Police in Congo have arrested 13 sorcerers accused of using black magic to steal or shrink men's penises after a wave of panic and lynchings triggered by the witchcraft. Rumours of penis theft began circulating last week in Kinshasa, Democratic Republic of Congo's sprawling capital of 8 million inhabitants. They quickly dominated radio call-in shows, with listeners advised to beware of fellow passengers in communal taxis wearing gold rings. Kinshasa residents accuse a separatist sect from nearby Bas-Congo province of being behind the witchcraft in revenge for a recent government crackdown on its members. "It's real. Just yesterday here, there was a man who was a victim. We saw. What was left was tiny," said 29-year-old Alain Kalala.Also Chinese men have been known to suffer from the shrinking/receding/disappearing penis syndrome, but they find effective magic remedies in their pharmacies. We Jews are unaffected by penis size anxieties, but according to Freud, suffer from castration complexes. Each people with its fears.
