Foreign Policy has an infographic in this month's issue about sex, and safe sex, around the world. Seems the number of sexual partners grows with income; people in low-income countries average 6.3 partners, while high-income countries average 9.7. People in high-income nations also have sex earlier, and are more likely to have unprotected sex – with nations like Norway, Denmark, Sweden, Australia and New Zealand at the head of the pack. Also, Icelanders and Germans lose their virginity earliest, and your sexual preference isn't a very likely determinant of whether or not you use protection. The info comes from the world's largest survey of sexual behavior, conducted by Durex (the condom purveyor). Fascinating.
