Oh, good gracious, no. I apologize for the cromulent lack of clarity of my posting. It was their husbands getting them pregnant.
By “not up to the woman’s desire” I mean (unclearly) that it wasn’t up to their sexual desire. The OP heard two moaning voices, so I was not only unclear, but tangential.
A side note: when I worked in LA County Hospital in the 1980’s, the clientele served was mostly people who couldn’t afford to go anywhere nicer. Many of them were poor rural women from other countries (chiefly Central American) whose culture included, so far as I and my colleagues could tell, more male sexual dominance within marriage than was permitted or considered acceptable in our middle-class families, and more emphasis on children as proof of a man’s success. Sort of like Hitler’s “kinder, kuche, kirche” for women. This meant that sometimes a married woman who was not interested in sex would give in to her husband’s desire to have sex, which is all I meant. The amazing thing was that any of them conceived. But some did.
