Celebrity Paris Hilton has launched a campaign to fight the spiralling problem of sexually transmitted diseases, and is urging women to pull back on promiscuity for the sake of their health. The reality TV star has shaken off her raunchy reputation after her 1 Night In Paris sex tape with Rick Salomon was exposed in 2004, and is reinventing herself as a positive female role model. And the socialite, who recently vowed to avoid sex for a year, is encouraging women to do the same and retain their dignity. She says, “It’s sexier when a girl is flirty but she doesn’t do anything. “I think women should be confident and strong, and they often underestimate themselves and give in to men. “Girls need to calm down and realise that sex isn’t everything. It’s frightening. Women are getting as bad as boys now for sleeping around.”
