Scarlett Johansson has criticised US President George W. Bush's conservative views on sex, saying he was too unrealistic in his opinions on the topic.

Bush takes an anti-abortion stance and is seeking to have the procedure made illegal in all US states. "We are supposed to be liberated in America but if our President had his way, we wouldn't be educated about sex at all. Every woman would have six children and we wouldn't be able to have abortions," Johansson said.
