The key is that African husbands tend to be more tolerant of their wives having a long term lover or two than is the norm elsewhere. The thought of one’s wife becoming pregnant by another man is intolerable to most husbands around the world, but tends to be less infuriating in Africa.

That probably stems from women doing most of the farm work in rural Africa. (That’s why you are always hearing about men in Africa working away from home in mines or wherever for months — the men aren’t often needed around the farm because most of the work is just hoeing weeds, which women can do at least as well as men.)

So, the husbands don’t have as much leverage over their wives’ behavior as in places where husbands are work-a-daddies bringing home the bacon. And African husbands don’t have as much motivation to enforce fidelity on their wives since they won’t be investing as much money in their wives’ children’s upbringing as they would elsewhere.

Another contributor to the high rates of AIDS in Southern/Eastern Africa besides multiple concurrent partners and lack of circumcision is the bizarre fetish for "dry sex," which I would guess doesn’t exist among West Africans because (thankfully) you never hear about it among their African-American cousins.

Dry sex?
