Professor G discusses the data on which country has the least amount of sex (impacted by religion more than anything else!) and which country has the most sex. They are 6 variables that account for each countries score: 1) Mean age of virginity lost, 2) average number of sexual partners, 3) STD rate, 4) % of people who consider premarital sex between consenting adults acceptable, 5) legality of prostitution, and 6) legality of premarital sex.
