Intercourse

Intercourse is a 1987 book by Andrea Dworkin, in which the author offers a radical feminist analysis of sexual intercourse in literature and society. Dworkin is often said to argue that "all heterosexual sex is rape", based on the line from the book that says "violation is a synonym for intercourse." However, Dworkin has denied this interpretation, stating, "What I think is that sex must not put women in a subordinate position. It must be reciprocal and not an act of aggression from a man looking only to satisfy himself. That's my point."
This it does with some consistency and some confidence. Violation is a synonym for intercourse. At the same time, the penetration is taken to be a use, not an abuse; a normal use; it is appropriate to enter her, to push into ("violate") the boundaries of her body. She is human, of course, but by a standard that does not include physical privacy.
