Ian Kerner, a sex therapist, opens with a personal confession: He had premature ejaculation (PE), a condition that left him feeling sexually inadequate. His initial forays into cunnilingus, the act of oral stimulation of a woman's genitals, began as compensation for this dysfunction. Over time, however, he discovered that oral stimulation was often the only way women received the persistent, rhythmic clitoral pressure necessary to reach orgasm. He describes the first time he brought a woman to climax with his tongue as a "watershed moment" that transformed his sex life and broader confidence. Kerner writes from the conviction that cunnilingus is not merely foreplay but what he terms "coreplay": a complete sexual act with its own beginning, middle, and end.
Modeled on Strunk and White's
Elements of Style, the book is organized into three parts. Part One, "The Elements of Sexual Style," establishes the philosophical and anatomical foundation. Part Two, "Rules of Usage," details specific techniques. Part Three, "Putting It All Together," offers integrated routines from beginner to advanced levels, with appendices addressing special situations. The overarching argument is that male gratification should be postponed until after a woman has achieved her first orgasm, a deferment Kerner contends enhances both her satisfaction and the quality of the male climax.
Part One argues that male and female arousal processes are fundamentally mismatched. Kerner cites sex researcher Alfred Kinsey's finding that 75 percent of men ejaculate within two minutes of beginning intercourse, and a 1994 University of Chicago survey showing that less than a third of women consistently reach orgasm during intercourse. He counters the objection that women take too long by citing studies showing that when partners spent 21 minutes or more on foreplay, only 7.7 percent of women failed to reach orgasm consistently.
Central to Kerner's argument is a redefinition of the clitoris. He contends it is not a simple "love button" but a complex organ system with 18 identified structures extending throughout the pelvic area. The clitoral glans alone contains approximately 8,000 nerve endings, twice as many as the head of the penis. Unlike the penis, the clitoris exists solely for pleasure, conferring upon women "an infinitely greater capacity for sexual response than a man ever dreamed of" (22). Kerner distinguishes "vulva," the full external genital area, from "vagina," which refers only to the internal canal. His anatomical tour covers visible structures such as the mons pubis (the fatty tissue over the pubic bone), the labia, the clitoral hood, and the perineum, as well as hidden structures including the clitoral shaft and crura (leg-like extensions), the clitoral bulbs, and the pubococcygeus (PC) muscle, which contracts during orgasm and can be strengthened through Kegel exercises, a set of pelvic-floor strengthening routines. Kerner rebrands the G-spot as the "clitoral cluster," arguing this term more accurately reflects its role as part of the clitoral network. Using this anatomy, he argues that all female orgasms are fundamentally clitoral, citing the condition of vaginal agenesis, in which women born without a vagina can still experience orgasm through their intact clitoris.
The tongue, Kerner argues, is the ideal instrument for clitoral stimulation: It is under direct voluntary control, works whether firm or soft, and eliminates concerns about premature ejaculation or erectile dysfunction. He cites a study in which wives in stable marriages rated cunnilingus the most satisfying sexual activity, reaching orgasm 81 percent of the time during oral sex compared to 25 percent during intercourse.
To explain why the clitoris has been widely misunderstood, Kerner traces a history of suppression. Through the 18th century, scientists believed the female orgasm was essential for conception. Victorian-era medicine characterized women's sexuality as weak and passionless, and anatomists reassigned clitoral structures to other organ systems. Sigmund Freud, the influential psychoanalyst, compounded the problem by classifying clitoral orgasms as "infantile" and promoting vaginal orgasm as the mature form, despite possessing clear anatomical knowledge to the contrary. Kerner cites the assessment of Dr. Thomas Lowry, author of the essay "The Cultural Psychology of the Clitoris," that Freud's notion "has probably caused more unnecessary worry than any other single psychological notion" (37). Figures such as Kinsey, the pioneering sex researchers William Masters and Virginia Johnson, sex researcher Shere Hite, sex educator Betty Dodson, and physician Mary Jane Sherfey restored accurate understanding through the sexual revolution.
Kerner addresses common sources of anxiety, explaining that a healthy vagina is a self-cleaning ecosystem and cautioning that wetness does not reliably indicate arousal. Part One concludes with "The Cunnilinguist Manifesto": Respect the female arousal process, postpone male gratification, appreciate the full clitoral network, and be patient and pleasure-oriented. He introduces the "Three Assurances" a man should communicate: that performing oral sex is genuinely arousing for him, that there is no rush, and that her scent and taste are desirable.
Part Two breaks coreplay into six stages. Stage 1 treats the first oral contact as a pivotal transition, advising a slow lick from the fourchette (where the inner lips converge below the vaginal opening) upward through the vulva rather than targeting the clitoral head. Stage 2 establishes rhythm through a make-and-break pattern of long vertical licks alternating with a flat, still tongue pressed against the vulva. Stage 3 introduces manual stimulation, with a finger entering the vaginal opening while the free hand supports the buttocks. Stage 4 escalates the action through internal stimulation of the clitoral cluster using a "come-hither" finger gesture against the vaginal ceiling, combined with external pressure on the mons pubis. Kerner also introduces the "gum-press," in which the upper gum is pressed against the front commissure, the point where the inner labia meet near the clitoral hood, creating resistance while the tongue stimulates the head.
Stage 5 focuses on reading signs of impending orgasm and maintaining steady, light stimulation rather than increasing roughness. Stage 6 describes orgasm as a series of involuntary contractions, on average 10 to 15 at 0.8-second intervals, and instructs the reader to maintain position while introducing "appoggiaturas," light tongue jabs that tease out additional pleasure.
Post-orgasm, Kerner discusses "moreplay." Women experience no refractory period, the mandatory recovery interval men require, making subsequent orgasms physiologically easier. For transitioning to intercourse, he recommends positions that maintain clitoral contact, such as the female superior position or the Coital Alignment Technique (CAT), which sustains clitoral pressure through rocking rather than thrusting. He warns against the "snuggle gap," urging men to stay connected after climax.
Part Three provides six integrated routines progressing from beginner to advanced levels. Advanced options include "The Tease," using exclusively surface strokes, and "The Tao of Cunnilingus," which prolongs the preorgasm phase by repeatedly approaching the edge before allowing release. Appendices cover manual stimulation, light restraint, modifications for men with PE or erectile dysfunction, safe oral sex techniques, guidance during menstruation and pregnancy, advice for first-time participants, and vibrator use.
The book concludes by reflecting on the film adaptation of Milan Kundera's novel
The Unbearable Lightness of Being, drawing a parallel between the protagonist Tomas's journey from meaningless sexual encounters to genuine lovemaking and the book's philosophy. Invoking philosopher Friedrich Nietzsche's idea of living each moment as though sentenced to repeat it eternally, Kerner connects this to making love with full presence. The final assertion encapsulates the thesis: When a woman comes first, she "comes forever," framing the approach as a philosophy of intimacy, respect, and mutual pleasure.
