http://www.npr.org/templates/story/s...toryId=5355494 Researchers surveyed sexual well-being in 29 nations, including countries they call "male-centered sexual regimes" where men generally control the sexual conduct of women, and "gender-equal sexual regimes" that emphasize equality between sexual partners. • The survey polled 13,882 women and 13,618 men aged 40 to 80. • Only 49 percent of men and 32 percent of women indicated that sex was extremely or very important to their overall life. • Men who had multiple sex partners were less likely to be satisfied with their relationships, but more likely to believe that sex was important. • Men report higher levels of sexual satisfaction than women, regardless of nation. • Asian countries all reported low levels of sexual satisfaction and moderate to low levels of satisfaction with their relationships and the importance of sex. • Israeli women placed the highest value on the importance of sex -- the lowest score came from women in Taiwan. Among men, Brazil scored the highest and Thailand the lowest. • Overall, people in Austria are most satisfied with their sex lives, and Japanese are least satisfied.
