That's the provocative headline of an Atlantic piece about two tribes in Africa. The piece begins:
Barry and Bonnie Hewlett had been studying the Aka and Ngandu people of central Africa for many years before they began to specifically study the groups' sexuality. As they reported in the journal African Study Monographs, the married couple of anthropologists from Washington State University "decided to systematically study sexual behavior after several campfire discussions with married middle-aged Aka men who mentioned in passing that they had sex three or four times during the night. At first [they] thought it was just men telling their stories, but we talked to women and they verified the men's assertions."
In turning to a dedicated study of sex practices, the Hewletts formally confirmed that the campfire stories were no mere fish tales. Married Aka and Ngandu men and women consistently reported having sex multiple times in a single night. But in the process of verifying this, the Hewletts also incidentally found that homosexuality and masturbation appeared to be foreign to both groups.
Sex is referred to as the "work of the night," as distinguished from the work the tribe does during the day. It's a really interesting read, but the bottom line is that the tribe relies on reproduction for its survival, so conjugal, life-producing sex is very important. And when that's the case, masturbation and homosexuality don't seem to be present in the culture (even though these tribes are aware that other groups engage in homosexuality).
We live in a country where adults estimate, on average, that 25% of the population is gay (in real life, that percentage is in the low single digits).
What, if anything, can we learn from the Hewlett's study of these tribes?
