Most husbands know that a wife who is trying to get pregnant can be less than romantic, and more like a Klingon female in the throes of mating. If you don’t know what that means, a Klingon female roars and claws at her mate.
And that compares reasonably well to something that a married woman said to me recently. We were talking about the process of trying to fall pregnant, and she said “Romantic love doesn’t make babies… primal love makes babies… and it can be a very empowering experience for a woman!”
Just for fun here’s a short Star Trek clip in which Worf describes the Klingon mating ritual to a very young and naive Wesley Crusher. And right at the end Worf gives him the option of trying what he considers to be the human approach to mating :
It’s a Primal Thing.
