It's a myth that men want sex and women want relationships, says a Sydney professor, as a long-simmering gender spat reaches Australia.
UK actor Stephen Fry caused a storm in 2010 when he said women have sex with men because it "is the price they are willing to pay for a relationship".
Although he has since described his statement as offensive, ignorant and arrogant, Australian sexual health expert Dr Juliet Richters is angry with sex theorists who, like Fry, "promote stories that are not supported by evidence and tell women how they should be and what they should like".
It is not true that men are focused only on sex and women only want relationships, she says.
In fact, there is evidence that as a relationship progresses, Australian men are more pleased with both.
