Couldn't you consider "marital prostitution" be done by any woman who marries a man who brings home the bread while she stays home and doesn't work? Ha ha!
We men want a woman who will give us a bath, wash our clothes, be our chosen prostitute, and be a child care provider to the children, and make good meals!
I restrict the term "prostitution" to the case where a woman marries exclusively for money, and has no actual emotional attachment for the guy, and would leave him immediately if he lost his money
