[M]y secret theory is that this isn’t the patriarchal possessiveness thing it appears to be. My secret theory is that men hate sluts because sluts are heartbreakers. You think you’re really special and worthy for a girl to sleep with you, and then you find out that she sleeps with lots of people, and it diminishes your specialness. If sex is a meaningful thing for you, finding out that it was meaningless for your partner is painful—legitimately so, sometimes. But admitting that you wanted meaningful sex and that you’re emotionally vulnerable is not manly, so instead guys just scream “SLUT!” like it’s just intrinsically wrong for a woman to have an interesting sex life.
