THE letter `S` means only one thing to Avatar babe ZOE SALDANA - sex. The US actress admits she "can`t live without" steamy bedroom romps, and refuses to rule out stripping off for X-rated scenes on camera. What`s more, she encourages people the globe over to flaunt more flesh. She told Essence mag: "I love sex. Love it, love it, love it... Can`t live without it. "I love skin. I don`t believe the body is something to hide." The 31-year-old - who played blue Na`vi alien Neytiri in JAMES CAMERON`s epic - also takes a pop at US culture, insisting it`s wrong that kids are being steered towards violence rather than pleasures of the flesh. She added: "I think in American society we`re messing up our kids by taking away the education on and awareness of our sexuality and replacing it with violence, guns and video games - and we`re breeding little criminals."
