Andrea Dworkin is not on record as saying that all heterosexual sex is rape, but she has said:
"No woman needs intercourse; few women escape it."
"Seduction is often difficult to distinguish from rape. In seduction, the rapist often bothers to buy a bottle of wine."
"Men are sexually predatory in life; and women are sexually manipulative."
"A commitment to sexual equality with males is a commitment to becoming the rich instead of the poor, the rapist instead of the raped, the murderer instead of the murdered."
"Penetrative intercourse is, by its nature, violent."
"Intercourse is the pure, sterile, formal expression of men's contempt for women."
"Violation is a synonym for intercourse."
