It's Procreation, Not Rocket Surgery

DADT in a different culture.
And they really mean, "don't tell":

And, the impact of those experiences is already being felt in portions of Afghanistan, putting American forces squarely in the middle of complex moral, social and sexual issues. A source at Army Special Operations command tells In From the Cold that Afghan women, emboldened by the presence of U.S. troops. have complained about beatings they've suffered at the hands of their husbands. The domestic violence reportedly stemmed from the inability of the women to become pregnant and produce sons, highly valued in Afghan society.

When U.S. civil affairs teams (and other special forces units) quietly investigated the problem, they quickly discovered a common denominator. Virtually all of the younger men who beat their wives (over their inability to become pregnant) had been former "apprentices" of older Afghan men, who used them for their sexual pleasure. Upon entering marriage, whatever the men knew of sex had been learned during their "apprenticeship," at the hands of the older man. To put it bluntly, some of the younger Afghans were unfamiliar with the desired (and required) mechanics for conception.
