Key Takeaways
97% of Americans fantasize — your desires are probably normal
“A lot of sexual desires have been deemed unusual despite being anything but.”
The largest fantasy survey ever. Sex researcher Justin Lehmiller surveyed 4,175 Americans with 369 questions and found that 97% reported having sexual fantasies — most several times per week. Seven major themes emerged that were shared by vast majorities regardless of gender, orientation, or background: multipartner sex, BDSM, novelty, taboo acts, nonmonogamy, passion and romance, and gender/sexuality flexibility.
Psychology has over-pathologized desire. One technical handbook catalogues 547 distinct paraphilias — supposedly unusual sexual interests — many of which Lehmiller's data revealed to be extraordinarily common. Dirty talk, food play, desire for novelty? All technically classified as paraphilias. The DSM once listed homosexuality alongside them. The range of "normal" sexual desire is far wider than the mental health community has admitted.
Group sex, BDSM, and novelty: America's three universal turn-ons
“…the American id is primarily characterized by desires to break free from cultural norms and sexual restraints.”
Three themes dominated. Over a third of participants named group sex — especially threesomes — as their all-time favorite fantasy. The appeal isn't about specific partners; it's sensory overload. BDSM rivaled it: just 4% of women and 7% of men had never fantasized about any form of bondage, dominance, submission, or sadomasochism. The third pillar — novelty — ranged from new positions to public sex to sex toys (85% had fantasized about those).
These three share a common engine: the desire to break routine. When we repeat the same sexual stimulus, arousal habituates — a pattern scientists call the Coolidge Effect. Group sex, BDSM, and novelty all inject enough variety to reverse this decline and reignite desire.
Most 'low libido' is shame about desire, not absence of desire
“The end result is that we wind up taking medications that, at best, might spur us into having mediocre sex more often.”
The pharmaceutical trap. When people suppress their real desires and force themselves into "acceptable" sex, satisfaction craters. Many get diagnosed with "low sex drive" and prescribed medications. But clinical trials showed the libido drug Addyi produced just 0.5 to 0.7 additional satisfying events per month versus placebo. The real problem isn't absent desire — it's desire for things we've been told are wrong.
Permission beats pills. Sex therapists using the PLISSIT model often find that simply giving clients permission to act on consensual desires — combined with proper sex education — resolves dysfunction that medication never could. Lehmiller's survey confirmed: participants who felt more guilt and shame about their fantasies reported significantly more sexual performance problems.
Same-partner arousal fades by design — novelty is the biological fix
“The couples who engage in the most acts of sexual novelty… tend to be the most sexually satisfied and the most successful at keeping passion alive.”
The Coolidge Effect explained. Named after a (possibly apocryphal) anecdote about President Calvin Coolidge visiting a chicken farm, this principle holds that arousal declines with the same sexual stimulus over time. Research confirms it: men shown the same porn clip daily for weeks showed declining arousal — until a new actress appeared. They then ejaculated faster and produced semen with more active sperm.
Novelty isn't betrayal — it's maintenance. This doesn't doom relationships. Couples who regularly introduce variety — new positions, sex toys, role-playing, even exciting nonsexual activities like roller coasters — report the highest sexual satisfaction. The Coolidge Effect isn't a design flaw; it's a signal to keep evolving together.
Women's sexuality is more flexible than men's, not less sexual
“The fantasy worlds that populate our minds are much more alike than they are different.”
The three-dial model. Lehmiller proposes sexuality involves three brain "dials": two control attraction to men and women (your orientation); a third controls sexual flexibility — openness to deviating from orientation and cultural norms. In genital arousal studies, straight women responded to all types of pornography regardless of actor gender, while straight men's arousal was category-specific. 59% of exclusively straight women reported same-sex fantasies versus just 26% of straight men.
Flexibility extends beyond partner gender. Women reported more BDSM fantasies of nearly every type — twice as likely as men to report frequent bondage fantasies, four times as likely for masochism. Despite these differences, men and women share all seven major fantasy themes. The real difference is frequency, not kind.
Your forbidden desires often mirror the rules you were raised with
“…the more political and moral restrictions we have placed on our sexuality, the more intensely we fantasize about breaking free of them.”
Reactance in the bedroom. Psychologists call it reactance: when freedoms are restricted, we rebel by craving exactly what's forbidden. Lehmiller found this across religion and politics. Religiously affiliated participants fantasized more about novel and taboo sex acts — the very things their faiths prohibit. Republicans fantasized more than Democrats about orgies, infidelity, swinging, cuckolding, voyeurism, and exhibitionism.
The pattern ran deeper. Heterosexual men with religious affiliations were more likely to have same-sex fantasies — possibly seeking faith to manage unwanted desires. Democrats, meanwhile, fantasized more about BDSM and emotional intimacy — desires reflecting psychological needs rather than rule-breaking. Sexual morality doesn't eliminate desire. It redirects it underground.
Young adults crave BDSM and romance; older adults want threesomes
“You've also reached the glorious 'zero fucks' stage of life, meaning you've realized that life is too short to spend it in a perpetual state of anxiety about what other people think.”
Counterintuitive age patterns. College-age adults were the least interested in threesomes — contrary to stereotypes. Sex itself is still novel at that age; no bells and whistles needed. But they're at peak insecurity, so they gravitate toward BDSM (which distracts from anxious self-awareness) and romance fantasies (which offer validation).
Middle-aged adults crave variety. After decades of sex — often with the same partner — the Coolidge Effect kicks in hard. But they're also more secure and less inhibited. So they crave group sex, nonmonogamy, and taboo acts to reignite arousal. Fantasies aren't random — they're precision instruments calibrated to meet evolving psychological needs as we enter new life stages.
Trying to suppress a fantasy only makes it come back stronger
“Stop running from your fantasies and start accepting them as part of who you are.”
The white bear problem. In Dan Wegner's famous Harvard study, participants told to suppress thoughts of a white bear still thought about bears more than once per minute — and later experienced a rebound effect, thinking about bears more than anyone else. Sexual fantasies follow the same pattern. Trying to banish unwanted desires makes them return with greater intensity.
Repression creates pressure. Research shows that when willpower is depleted by sustained effort, people become worse at resisting urges. Acknowledging what Lehmiller calls the shadow self — the desires we've been taught to fear — doesn't require acting on every fantasy. It requires honesty. Notably, people who had acted on BDSM fantasies reported higher self-esteem than those still hiding them, mirroring the well-documented mental health benefits of coming out.
Tell your partner what you want — fear of rejection is usually wrong
“We just need permission to share what it is that really turns us on — to tell each other what we want.”
The disclosure gap. Among those who hadn't shared their favorite fantasy, a majority expected negative reactions. But among those who actually shared, 74 – 82% reported positive responses for romance, novelty, and BDSM fantasies; 65 – 69% positive even for group sex and nonmonogamy. Negative reactions ranged from just 6% to 22% depending on the fantasy.
Self-disclosure builds intimacy. Research shows couples who share more report greater love, longer-lasting relationships, and fewer bedroom problems. Lehmiller's practical guidance: disclose gradually, choose private settings when both partners are already aroused (arousal reduces the disgust response), validate your partner throughout, and attend to body language. Consider sexual icebreakers — erotic films, sex-shop visits, or adapted versions of Arthur Aron's 36-question intimacy exercise.
86% who acted on fantasies said reality met or beat the dream
“The biggest perceived obstacles are thinking that one's partner would be unwilling or disapproving of the activity, not knowing how to go about it, and being afraid to try it.”
The action gap. Only one in three Americans had acted on their biggest fantasy, despite 79% wanting to. Among those who did, 86% said reality met or exceeded expectations, and 91% reported neutral-to-positive relationship impact. Nonmonogamy fantasies had the highest satisfaction rate (92%); group sex the lowest — largely because there's no cultural script for how a threesome unfolds.
Who fares best? People in satisfying relationships, with high self-esteem, high sex drives, and low neuroticism. Lehmiller's practical framework for acting on fantasies:
1. Ensure the fantasy is safe, sane, consensual, and legal
2. Establish a safe word
3. Research best practices from expert sources
4. Take baby steps before escalating
5. Provide aftercare — gentle contact and debriefing afterward
Ditch the soulmate myth — invest in skills, not destiny
“Put simply, we're effectively demanding that partners meet two contradictory needs at the same time: stability and surprise.”
Destiny beliefs destroy relationships. Up to three-quarters of Americans believe in soulmates, and the number is rising among millennials. But research shows destiny believers work less to resolve conflict and break up faster — they interpret friction as evidence of a mismatch rather than a challenge to overcome. Meanwhile, passion naturally declines after six to thirty months in most relationships. This isn't a sign something is wrong; it's the Coolidge Effect.
Flexibility beats fate. Successful long-term couples fight habituation through sustained novelty — in and out of the bedroom. And if monogamy doesn't serve both partners' needs, consensual nonmonogamy is a legitimate path. Studies show polyamorous and open relationships match monogamous ones in satisfaction and commitment. The key: know yourself, develop communication skills, and chart your own course.
Analysis
Lehmiller's work represents the most ambitious empirical attempt to map American sexual desire since Kinsey's mid-century surveys, though with important methodological differences. Where Kinsey relied on in-person interviews, Lehmiller used anonymous online surveys recruited via social media — a trade-off that likely yielded more honest responses but introduced selection bias toward digitally engaged, sex-positive respondents. The author acknowledges this candidly, noting his findings probably overestimate how many Americans have shared or acted on their fantasies.
The book's central argument — that psychology has systematically pathologized normal desire through the paraphilia label — is both its strongest contribution and its most provocative claim. By demonstrating that desires classified as 'unusual' by the DSM are held by statistical majorities, Lehmiller effectively inverts the diagnostic framework. The implicit question becomes uncomfortable: if 60% of people fantasize about voyeurism, who exactly qualifies as deviant?
However, the normalization project carries its own risks. Statistical frequency and psychological health are not synonymous, a distinction the author acknowledges in principle but occasionally underplays in rhetoric. The evolutionary psychology explanations — sperm competition, alloparenting hypotheses, sexual imprinting windows — are presented with appropriate tentativeness but remain largely unfalsifiable adaptive stories.
The three-dial model of sexuality, distinguishing orientation from flexibility, may be the book's most useful theoretical innovation, offering a framework that elegantly explains why identity labels never capture the full picture. The reactance findings — that moral restrictions amplify forbidden fantasies — have implications well beyond sexuality, illuminating the psychology of prohibition generally.
Perhaps the book's most quietly radical insight is that BDSM practitioners who are 'out' about their desires report higher self-esteem than those still hiding — mirroring the psychological trajectory of LGBTQ+ acceptance. This suggests that sexual shame, not sexual desire, is the real pathology worth treating. The concept of the shadow self — desires we suppress out of fear — emerges as the book's central therapeutic target.
Review Summary
Tell Me What You Want presents findings from a large survey on sexual fantasies. Readers found it informative and normalizing, appreciating its sex-positive stance and accessible writing. However, some criticized its focus on heterosexual, cisgender experiences and questioned the scientific rigor. Many felt the book was repetitive and overly speculative at times. While some found practical advice for improving their sex lives, others wanted more diverse representation and nuanced analysis. Overall, reactions were mixed, with readers valuing the attempt to destigmatize fantasies but noting limitations in methodology and scope.

Glossary
Coolidge Effect
Arousal fades with repetitionThe observation that sexual arousal habituates—decreases over time—in response to the same sexual stimulus. Named after an anecdote about President Calvin Coolidge visiting a chicken farm. Reversible by introducing novelty, such as a new partner, activity, or setting. Documented in laboratory studies showing declining arousal to repeated porn clips and increased arousal when new stimuli appear.
Sexual flexibility
Openness to deviating from normsA dimension of sexuality distinct from sexual orientation. Lehmiller describes it as a 'third dial' that controls willingness to deviate from one's underlying orientation and cultural sexual norms. High flexibility means greater openness to experimenting with partner gender, new activities, and norm-breaking behaviors. Women's flexibility dials tend to be turned higher than men's, supported by genital arousal studies and fantasy survey data.
Reactance
Rebelling against restricted freedomsA psychological phenomenon in which people respond to perceived restrictions on their freedom by doing or desiring the opposite of what is demanded. In Lehmiller's context, religious and politically conservative individuals fantasize more intensely about sexually forbidden acts—precisely those their moral authorities prohibit. Reactance explains why abstinence-focused messaging often paradoxically increases interest in restricted behaviors.
Shadow self
Hidden desires we fear acknowledgingA concept borrowed from psychology referring to the part of oneself composed of desires and urges—especially sexual ones—that a person suppresses because they believe they shouldn't have them. Lehmiller argues that accepting the shadow self rather than repressing it is essential for sexual well-being, because cordoning off these desires leads to shame, performance problems, and loss of control over one's desires.
Paraphilia
Labeled 'unusual' sexual interestA preference for nonnormative sexual activity or target as defined by the DSM (Diagnostic and Statistical Manual of Mental Disorders). Lehmiller challenges the concept, arguing that many formally designated paraphilias—including sadism, masochism, fetishism, and transvestism—are statistically common based on his survey data. He contends that the paraphilia label has been applied too freely and has stigmatized normal desires.
Self-expansion theory
Growth need driving relationship noveltyA theory by psychologist Art Aron proposing that humans have an innate need to continually grow and expand the self through new experiences, knowledge, and relationships. Lehmiller applies it to explain why consensual nonmonogamy and sexual novelty are appealing: monogamous sex can become predictable, and new partners or activities fulfill ongoing expansion needs while allowing a primary relationship to continue.
Erotical illusions
Mixed gender cues amplifying arousalA term from neuroscientists Ogi Ogas and Sai Gaddam describing unique combinations of sexual cues—such as masculine and feminine physical characteristics in the same person—that together produce an unusually intense state of sexual arousal, greater than either cue would generate alone. Used by Lehmiller to explain the appeal of transgender and androgynous partners in sexual fantasies, particularly among heterosexual men.
