Why people have sex: It feels good - Yahoo! News: "'It's refuted a lot of gender stereotypes ... that men only want sex for the physical pleasure and women want love,' said University of Texas clinical psychology professor Cindy Meston, the study's co-author. 'That's not what I came up with in my findings.'

Forget thinking that men are from Mars and women from Venus, 'the more we look, the more we find similarity,' said Dr. Irwin Goldstein, director of sexual medicine at Alvarado Hospital in San Diego. Goldstein, who wasn't part of Meston's study, said the Texas research made a lot of sense and adds to growing evidence that the vaunted differences in the genders may only be among people with sexual problems."
