Zelijko Tupic was having difficulty sustaining an erection. So he decided to force a pencil inside his penis. When it got lodged inside his bladder during sex, he phoned for an ambulance. Doctor Aleksander Milosevic expressed his concern about Tupic’s methods, and told him to “try Viagra pills before he takes any chances with pencils.” Rubbers are fine, however.
