According to researchers at the University of Chicago, sex is best when it is with a social equal. The study of 29 nations shows that male-centered cultures like those found in Japan and the Muslim world have the least satisfied sex participants. The researchers were actually kicked out of Saudi Arabia for asking sex-related survey questions, however many other Muslim, male-dominated countries did participate.
In addition to the social data reported, other information showed: monogamy and commitment were found to be cherished throughout the world, despite great differences in culture and tradition; foreplay (5 to 30 minutes) has a positive association everywhere, especially for women; and data on female sexual dysfunction were similar around the world.
