Actress Scarlett Johansson finds shooting intimate scenes both "challenging" and "liberating".

The actress thinks love-making on screen is challenging because it requires so much focus and energy and she likes how she has to shed her inhibitions for raunchy roles.

"You have to be totally without judgement, and it's sort of liberating. It's challenging. You have to stay in the moment,` contactmusic.com quoted Johansson as saying.

Despite her stunning looks and enviable physique, the actress, who has two-month-old daughter Rose with husband Romain Dauriac, doesn't consider herself sexy.

"It's an OK body. I wouldn't say it's particularly remarkable though. I don't like my thighs, my mid section,` she said.
