Paris Hilton refused to perform fellatio on boyfriends until she was 19, after her mother told her the sex act would leave her with facial craters. The sexy blonde first gave oral sex to ex-boyfriend RICK SALOMON, the cad who turned the couple's sex tape into porn hit ONE NIGHT IN PARIS. Until then she was convinced the very act would leave her deformed - thanks to a frightening warning served up by her mother Kathy Hilton. Hilton tells Blender magazine, "My mom told me that you get those holes in your face, craters... from giving blow jobs. "I totally believed her. She's like, 'It's from sucking.' I'm like, 'Ewwww!' "I told my boyfriend - he's like, 'Why don't you ever do that?' I'm like, 'Because my mom told me you get these craters.' And he's like, 'Paris, you're 19. You're allowed to do this.' "I've only done that (fellatio) with maybe three people in my life."
