Could this also explain the inexplicable?
i.e.: mothers pushing their young sons to grow up to be martyrs for the One True Religion

I don't know if the practice of infibulation makes a culture more murderous, but I'm sure it doesn't make them more passive toward the "uncut".
Heck if they're not getting any pleasure from sex, and the men have this kind of attitude toward women, maybe these moms are doing their society a favor.
(Speaking rhetorically of course.)
