Zoe Saldana "can't live without" sex.

The 'Avatar' actress - who lives with her long-term boyfriend Keith Britton - is proud of her body and thinks people should be encouraged to take a greater interest in their sexuality from a young age to stop them turning to crime.

She said: "S is for Sex. Love it, love it, love it"can't live without it.

"I love sex. I love skin. I don't believe the body is something to hide. 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."

The 31-year-old star also admitted she won't rule out ever starring in a graphic sex scene in any of her movies.

She told Essence magazine: "If you asked a painter, 'Are you going to paint in red?' the answer would be, 'I'm going to paint paintings and if one day there is red in it, there's red in it.' "

Speaking about her relationship, Zoe admitted she always wants to experience "severe passion".

She added: "I'm more of a punch-drunk-love kind of girl. I mean punch as in that pow, that jolt, that kick in the gut. I like things that are severe, passionate and extreme."
