Misinformation on sexual matters is rife: 40% of secondary school students in Zimbabwe thought that HIV could be caught from toilet seats; most Indian men believe that masturbation weakens a person and that sexually transmitted diseases could only be transmitted by prostitutes but not by girlfriends or domestic servants; many young people believe that pregnancy cannot occur without ejaculation; in sub-Saharan Africa, older men (or 'sugar-daddies') often believe that having sexual relations with a young or virgin girl will cure a sexually transmitted disease or prevent exposure to HIV.
