The Case Against the Sexual Revolution

Louise Perry, 2022. Perry begins with a challenge to liberal feminism: abolishing old sexual rules does not automatically create a system that serves women well.

Her argument is that the sexual revolution treated a particular kind of male sexuality as the model of freedom: less attachment, fewer obligations, more access, and the assumption that voluntary desire is enough to justify an encounter. In a market built around that model, the people best positioned to win are those who can most easily detach sex from love, face less reproductive risk, and leave with fewer consequences. On average, Perry argues, that group is more male than female.

The book therefore defends not every old sexual rule but the idea of sexual norms itself. Rules matter when formally free adults face different incentives, risks, and physical capacities.

1. Sex Must Be Taken Seriously

Perry opens with Hugh Hefner and Playboy culture. Hefner is useful to her because he presents the revolution in its most attractive form: old restrictions are hypocrisy; sexual availability is liberation.

Her objection is that sex is not an ordinary consumer transaction. It can produce pregnancy, jealousy, attachment, vulnerability, violence, reputation effects, and family obligations. A person can consent to one event and still face consequences that cannot be cancelled as easily as the decision itself.

Perry rejects the liberal stopping rule that says society has nothing further to discuss once consenting adults are involved. A culture can systematically reward bad choices even when each choice is technically voluntary.

2. Men and Women Are Different

The second chapter argues against treating sex as a blank slate written entirely by culture.

Perry does not claim that every man or woman behaves alike. She argues that average differences matter in large mating markets: pregnancy is female, men are on average physically stronger, and male and female sexual strategies do not perfectly overlap.

She applies this especially to sexual violence. Biological difference does not excuse aggression; for Perry it makes self-restraint and realistic safety norms more important. A rule built for interchangeable bodies will distribute risk badly when bodies are not interchangeable.

3. Some Desires Are Bad

Perry next rejects the idea that desire acquires moral legitimacy simply because it exists.

People can want things that damage themselves or others. Every culture therefore makes distinctions among ways of pursuing desire. Consent matters, but desire itself cannot be the whole moral argument.

Here she introduces the sexual-market logic that runs through the book. When norms weaken, people comfortable with short-term, low-obligation sex gain bargaining power. People seeking slow courtship, monogamy, or sex only inside a serious relationship must operate in a market written by someone else’s preferences.

For Perry, a norm-free market is not neutral. It is a market with an implicit norm favoring the least constrained strategy.

4. Loveless Sex Is Not Empowering

Perry criticizes a particular feminist response to the old sexual double standard. If women were once punished for sexual freedom, it does not follow that liberation must mean learning to detach sex from attachment in the same way as the most sexually unrestricted men.

She argues that women are on average more selective about casual sex and more likely to care about emotional security and a man’s continuing interest. A culture that treats detachment as sophistication can therefore pressure women to suppress rather than express their preferences.

The chapter also focuses on mismatched expectations. A man may see a short affair as exactly what was agreed. A woman may read intimacy as movement toward a relationship. Without shared norms, both can enter the same encounter under different models of what it means.

5. Consent Is Not Enough

Consent is indispensable in law: without it, sex becomes assault. Perry objects to turning that legal minimum into a complete moral theory.

People consent under the influence of money, hierarchy, loneliness, dependency, fear of losing a partner, or industries designed to manipulate attention. A formal yes does not settle whether someone is being treated well.

Pornography is her main example. She describes an industry in which the language of choice can coexist with economic pressure and an escalating market for more intense material. She also turns the lens toward consumers: digital abundance can train attention around endless novelty and make ordinary intimacy comparatively dull.

Her conclusion is straightforward: “they agreed” begins the moral inquiry; it does not finish it.

6. Violence Is Not Love

The sixth chapter attacks the normalization of aggression inside sexual culture.

Perry objects to the idea that a dangerous act becomes morally uninteresting once it is sexualized and technically consented to. Her argument again rests on physical asymmetry: men can on average inflict more physical harm, so a culture should not eroticize male aggression while teaching women that tolerating it proves sophistication.

She does not propose police supervision of private bedrooms. Her demand is cultural: restore a distinction between care and harm. In her model, love requires the stronger person to exercise restraint rather than to test how far permission can be stretched.

7. People Are Not Products

Perry then turns to prostitution, commercial sexual content, and the sale of sexualized attention.

She rejects “sex work is work” as an incomplete argument. Economic transactions can involve bodies without making every bodily transaction an ordinary commodity exchange.

She emphasizes selection effects: the harshest parts of the sex market disproportionately fall on people with fewer alternatives, while public narratives of empowered choice often feature the most privileged sellers.

Digital sexual commerce also has a relationship cost. A person may make money from sexual visibility while changing how future partners assess trust, exclusivity, and long-term compatibility. The market for purchased attention and the market for a spouse are not governed by the same incentives.

8. Marriage Is Good

The final chapter defends monogamous marriage as a social technology.

Perry does not describe the past as a golden age. Old marriages could be unjust, contraception increased freedom, and divorce can be necessary. Her argument is that marriage cannot be reduced to male control.

Marriage ties sex to fatherhood, turns a man’s continuing presence into an expectation, creates obligations between adults, and gives children a more stable framework. Romantic feeling changes; pregnancy, sickness, exhaustion, unemployment, and childcare repeatedly make the relationship unequal in the short term. A promise matters because two independent people cannot profitably renegotiate the relationship from zero every morning.

Perry describes monogamy as a compromise between the sexes. Men give up access to unlimited partners; women receive a stronger claim on male commitment. Both exchange some freedom for a shared project.

Conclusion: Listen to Your Mother

Perry ends mainly by addressing young women. She does not call for a return to a world in which fathers, churches, or public shame control female sexuality.

Her argument is that self-restraint should not automatically be treated as oppression.

Choose men for character as well as chemistry. Do not treat casual sex as a compulsory badge of modernity. Do not confuse danger with liberation. Prefer social settings where reputation matters. If family is the goal, treat marriage as an institution rather than a decorative ceremony.

The book’s final claim is that sexual freedom without norms did not abolish power. It shifted power toward people who function best in a market without obligations.
