Meston and colleague David Buss first questioned 444 men and women — ranging in age from 17 to 52 — to come up with a list of 237 distinct reasons people have sex. They ranged from “It’s fun” which men ranked fourth and women ranked eighth to “I wanted to give someone else a sexually transmitted disease” which ranked on the bottom by women.

Once they came up with that long list, Meston and Buss asked 1,549 college students taking psychology classes to rank the reasons on a one-to-five scale on how they applied to their experiences.
