This article is based on a review of recent scientific literature concerning sexual desire in couples, as well as on my academic research on the flexibility of sexual scripts within couples.
"He wants it all the time, I never do." "She doesn't want me anymore." "I feel rejected." "I feel harassed." Discordance of desire —also called a difference in libido, asymmetry of desire—refers to the situation where two partners in a couple do not experience the same level of sexual desire, in frequency, intensity, or form. It is by far the most common reason for couples seeking sex therapy. And it is also one of the most misunderstood phenomena: almost all couples who seek help arrive convinced that one of them has a problem—a libido that is "too low" or "too high." Contemporary research demonstrates precisely the opposite: discordance of desire is not a symptom of either partner. It is a characteristic of the couple, and it is addressed at the couple level.
In the discordance of desire, the patient is neither the one who wants more, nor the one who wants less: it is the space between the two.
Is a discrepancy in desires normal?
Yes—so much so that the question deserves to be turned on its head: it is perfect and lasting synchronization that is exceptional. Two distinct individuals, with different histories, hormones, stress levels, and modes of desire, cannot be permanently synchronized. The work of researcher Kristen Mark (2015), a specialist in this area, establishes that a difference in desire is a nearly universal experience for long-term couples, and that its magnitude fluctuates over time within the same couple.
The central finding of this literature is counterintuitive and liberating: it is not the size of the gap that predicts couple dissatisfaction, but how the couple manages it .
An important distinction must be made: a discrepancy in desire is not the same as "hypoactive sexual desire disorder." This clinical diagnosis applies only to situations where the decreased desire is experienced as distress by the individual themselves —not to situations where it is only problematic in comparison to the other person's desire. Having less desire than one's partner is not a pathology; it is a difference.
Why are our desires not synchronized?
Three well-documented mechanisms explain the gap — and none of the three is a matter of love.
Two modes of accessing desire. Research distinguishes between spontaneous desire (desire arises on its own, before any contact) and responsive desire (desire emerges in response to the context, once intimacy has begun). According to data summarized by Emily Nagoski (2015), approximately 75% of men but only 15% of women operate primarily in a spontaneous mode, while about 30% of women operate in a responsive mode and nearly half in a mixed, highly contextual mode. In a typical couple, one partner therefore anticipates a desire beforehand, the other anticipates a desire afterward—and each mistakenly concludes that the other "doesn't want to" or "is only thinking about that."
The accelerator and the brake. Bancroft and Janssen's dual control model describes the sexual response as a balance between an excitation system (the accelerator, sensitive to erotic stimuli) and an inhibition system (the brake, sensitive to stress, fatigue, pressure, insecurity, and resentment). What we call a "low libido" is very rarely a failure of the accelerator—it is almost always an overload of brakes : mental load, unfairness of household chores, exhaustion, unspoken resentments, and feelings of obligation. You don't revive a suppressed desire by pressing harder on the accelerator; you revive it by releasing the brakes.
Desire as a property of the couple: the DIADICS model. The most recent theoretical advance comes from a model still unknown to the general public: the DIADICS model ( Dyadic Interactions Affecting Dyadic Sexual Desire ), proposed by Prekatsounaki and his colleagues in 2022. This model formalizes what clinicians have long observed: sexual desire is not an individual state that each person "brings" to the encounter, but an emergent property of the marital system . Each partner simultaneously occupies two positions—that of a subject who perceives and acts, and that of an object perceived by the other—and these positions function in a feedback loop: the desire of one influences the desire of the other through the continuous mediation of mutually aroused perceptions, behaviors, and emotions. Concretely: the way you react to your partner's desire (or lack thereof) is part of their desire. This is why the question "who has a libido problem?" is poorly framed—desire plays out between the two.
"I even avoid hugs": when discord contaminates all tenderness
This is one of the most painful stages of mismatched desire, and one of the most frequent in therapy: the partner with the lower desire—most often the woman in heterosexual couples—ends up avoiding not only intercourse, but all physical contact : kisses, evening cuddles, a hand on the shoulder. This phenomenon, which recent research allows us to describe precisely, follows an implacable logic.
The shift in the meaning of touch. When, for months or years, every gesture of tenderness has systematically transformed into an attempt at sexual initiation, affectionate touch undergoes what the psychology of communication calls a shift in valence: it is no longer interpreted as gratuitous tenderness, but as the first step in a desire. The brain learns the association—and it learns quickly. The neuroscience of touch shows that a gentle caress, normally mediated by specific nerve fibers (C-tactile fibers) that trigger calming and the release of oxytocin, literally changes its brain processing depending on the perceived intention: anticipated as pressure, the same caress activates the alert circuits instead of those of attachment. Hence the bristle reaction described by so many patients: this sudden, involuntary twitching when their partner embraces them. This is not a rejection of the person — it is an automated somatic defense, the body saying "too much pressure".
The demand-withdrawal cycle. This dynamic is self-perpetuating, following the most well-documented pattern in couple psychology: the more the demanding partner insists (through requests, reproaches, and allusions), the more the other withdraws; the more the other withdraws, the more the demand intensifies. The meta-analysis by Schrodt and colleagues (74 studies, over 14,000 participants) establishes that this demand-withdrawal cycle is one of the strongest predictors of marital dissatisfaction—with particularly strong correlations in the "demanding man/withdrawing woman" configuration, precisely that of the typical desire mismatch.
The trap of sex out of obligation. Many partners with lower desire initially try to "make an effort" by accepting unwanted sex to preserve the peace in the relationship—what research calls sexual compliance (Impett & Peplau, 2003), often preceded by a "self-silence" where the person conceals their own boundaries for fear of conflict. The result is consistently counterproductive: sex out of obligation, experienced without arousal or desire, reinforces the negative association between contact and constraint, and accelerates avoidance. The same is true for transactional dynamics—sex as currency, domestic bargaining ( choreplay )—which strip touch of its gratuitousness and fuel bodily distrust. In the most severe cases, repeated intercourse without adequate arousal can contribute to genuine genito-pelvic pain (grouped since DSM-5 under the diagnosis of genito-pelvic pain/penetration disorder), which locks avoidance into the body.
How to resolve the discordance of desires?
The good news is twofold: desire discordance is the best-understood problem in contemporary sexology, and the interventions that work are well identified.
Reframing the problem correctly : as long as the couple focuses on which one is "broken," they will only dig themselves deeper into trouble. The first therapeutic step involves externalizing the problem—it's neither him nor her, it's the gap and how it's managed. The DIADICS model provides a valuable framework here: each partner discovers how their own reactions contribute to the other's desire (or lack thereof).
Protecting unconditional tenderness : A large-scale study conducted by Floyd and his colleagues with 700 married individuals showed that non-sexual affectionate communication—greeting kisses, hugs, neutral caresses—acts as a buffer : in highly affectionate couples, a decrease in sexual frequency does not lead to a decrease in marital satisfaction. In practice, this often involves an explicit agreement: spaces for tenderness completely detached from any sexual expectation, guaranteed as such. This allows touch to regain its meaning—and, in the responsive partner, to reopen the door through which desire enters.
Lifting the brakes rather than forcing the accelerator : an honest inventory of what loads the inhibitory system — mental load, domestic inequity, resentments, fatigue, medical factors (treatments, hormonal contraception, thyroid) — and concrete work on it.
Relearning touch in stages : when tactile avoidance is established, sex therapy mobilizes progressive protocols from sensory focus , where sexual intercourse is temporarily suspended — which lifts the anxiety of escalation — while the couple relearns sensory contact without stakes, before very gradually reintroducing genital intimacy, at the pace of the more cautious partner.
Negotiating the script rather than the frequency : the core of the work lies in the flexibility of sexual scripts —the couple's ability to evolve their scenarios rather than imposing a "yes" or "no" on a single script. Flexible couples don't seek to agree on the frequency of a specific type of sexual encounter; they broaden the range of possible encounters, so that a difference in energy or desire becomes an area for negotiation ("we invent a halfway encounter") and not a binary impasse. Research is unambiguous on this point: the first longitudinal study conducted on 74 couples (Bouchard et al., 2023) shows that one partner's flexibility predicts the sexual satisfaction of both —it's a resource that circulates within the couple.
Specialized consultation : When the cycle of demand and withdrawal is locked, when tenderness has disappeared, or when pain has set in, a combined approach—couples therapy, sex therapy, and, if necessary, pelvic floor rehabilitation—allows the problem to be addressed on all levels. This work lends itself very well to online consultations, which also offer each participant a more comfortable setting to express what is no longer possible to say face-to-face.
Conclusion: the gap is not the problem — the impasse, however, is.
A discrepancy in desire is neither an anomaly, nor a verdict on the couple's love, nor the fault of the partner who desires less or the one who desires more. It is an almost inevitable difference between two people who share a life—and it only becomes destructive when the couple manages it through pressure, duty, or avoidance.
The scientific data converges: what distinguishes couples who get through discord from those whom it damages is not the magnitude of the gap, but the flexibility of the response — the ability to protect tenderness, to remove the brakes, and to rewrite together a scenario where two different desires can still meet.
