Many women do more than that when they're alone with themselves. But the contrived rules do not allow them to relax with a partner. It is not without reason they say, that a smart woman has it in her head, a fool has it in her mouth. I even know men who categorically reject such liberties.
Asian women all get fucked for money. Husband or no husband, it doesn't matter. They say if a woman is chosen by tourists for this, it means she brings happiness to the family. Fucking breadwinners! So they can stab them openly, and the husband will sit in the hallway - waiting for her to earn. And of course, just like our chicks, African dick is a thrill. It's almost like intercourse with an alien - Welcome to Earth, friends!
Why would you do that?
