Out of interest, what about male prostitution? Is it possible for a man to be paid for sex "and to have a whole human being at the end of it"?
I suppose in a society where women were free of patriarchy and rape culture, and had full reproductive and sexual autonomy, then Dworkin's statement wouldn't even apply to women.
But that society is a fantasy, and I doubt any capitalist society could ever free women from economic exploitation of their bodies by others.
