The good-enough-sex model, for couples exhausted by great sex pressure
Clinical psychologist Barry McCarthy's alternative to performance-driven expectations argues most sex should be good enough, not great — and that the difference matters.
There is a particular kind of tired that has nothing to do with sleep. It shows up in couples who, on paper, are doing everything the culture tells them to do about their sex life — they're trying, they're prioritising it, they've read the articles — and who are somehow more anxious about intimacy than couples who barely think about it at all. The pressure to be good at this, to have great sex regularly, to keep the spark alive, has become its own obstacle to actually wanting each other.
Clinical psychologist Barry McCarthy has spent decades working with exactly this couple, and the model he developed for them has a deliberately unglamorous name: good enough sex. It is not a lowered bar out of resignation. It is, according to McCarthy's clinical experience and the broader research on realistic sexual expectations, a considerably more accurate map of what sustainable long-term sexual connection actually looks like than the "great sex, every time" story most couples are quietly measuring themselves against.
The problem the model was built to solve
McCarthy, co-author of Rekindling Desire and Discovering Your Couple Sexual Style, works primarily with long-term couples navigating desire and performance concerns. Across that clinical population, he identified a pattern that will be familiar to a lot of readers even outside a therapy room: couples arrive with what he calls perfectionistic or performance-oriented expectations of sex, modelled heavily on media, pornography and a cultural narrative that treats sex as something that should be spontaneous, mutually orgasmic, and roughly transcendent, every time it happens.
That standard is not just difficult to meet. For most long-term couples, most of the time, it is close to impossible to meet — and McCarthy's argument is that treating it as the baseline is actively corrosive. When "great" is the expected outcome, anything short of it reads as failure, and failure invites either performance anxiety, avoidance, or both. Couples stop initiating not because they don't want each other, but because they don't want another data point confirming that sex "isn't working" the way it's supposed to.
What "good enough" actually means
The name invites an obvious misreading — that McCarthy is arguing for settling, or for mediocre sex as an acceptable ceiling. That is not the model. Good enough sex describes a realistic range of outcomes, most of which are genuinely satisfying, without requiring every encounter to hit the top of that range to count as a success.
In McCarthy's framework, most sexual encounters in a healthy long-term relationship fall somewhere in a wide band: pleasurable, connecting, and worthwhile, without being maximally intense, perfectly synchronised, or mutually orgasmic every time. A smaller number of encounters will be genuinely great. A smaller number again will be mediocre, low-energy, or not really work — and crucially, that is treated as normal variation rather than a warning sign. The couples McCarthy sees doing well are not the ones who never have an off encounter. They are the ones who don't treat an off encounter as evidence of a bigger problem.
This reframes what "success" means at the level of a single encounter. Under a great-sex standard, an encounter that isn't intensely satisfying is a failure. Under a good-enough standard, that same encounter is just one ordinary data point in a much wider, more forgiving distribution — most of which counts as fine, some of which counts as very good, and a normal minority of which just doesn't land, without anyone needing to assign blame.
Why variability is the feature, not the bug
A core piece of McCarthy's model, and one that lines up with the broader research on sexual satisfaction in long-term couples, is that variability itself is normal and expected rather than a sign of a relationship losing its spark. Desire fluctuates with stress, sleep, hormones, life stage and a hundred other variables that have nothing to do with attraction. Expecting flat, consistently high performance from a system that is inherently variable sets couples up to misread ordinary fluctuation as decline.
This matters particularly for the partner more prone to performance anxiety — often, though not exclusively, men worried about erectile reliability, or either partner worried about their own responsiveness. McCarthy's clinical work on male sexuality specifically targets the anxiety loop where one difficult encounter gets catastrophised into "something is wrong with me," which then makes the next encounter more anxious and more likely to be difficult, and so on. Naming variability as expected — rather than as a problem requiring diagnosis — interrupts that loop before it compounds.
The role of realistic expectations in desire itself
There's a less obvious mechanism at work here too, one that connects directly to desire rather than just performance anxiety. Pressure and desire tend to work against each other. Sex approached as a test to pass generates the kind of vigilant, self-monitoring mental state that is close to the opposite of the relaxed, present state most people need to actually get aroused. This is part of why so many couples report that the more they focus on "fixing" their sex life, the worse it seems to get — the fixing itself has become another performance to fail at.
Good enough sex removes a layer of that pressure by changing what's being aimed for. If a wide range of outcomes counts as worthwhile, an individual encounter doesn't have to carry the weight of proving anything. That lowered stakes, paradoxically, tends to make genuine desire more accessible, not less — which is the same dynamic we've explored from a different angle in why anticipation matters more than spontaneity for desire: systems under pressure to perform well don't relax into wanting; systems given permission to be ordinary often do.
What this looks like in practice
McCarthy's model isn't purely conceptual — it comes with practical shifts couples can make. One is redefining what counts as a "successful" sexual encounter away from a narrow, orgasm-and-intensity-focused definition toward a broader one that includes closeness, playfulness, and mutual pleasure that doesn't need to peak dramatically to be worthwhile. Encounters that end in laughter, in comfortable stopping partway through, or in low-key affection rather than a climactic finish still count.
Another is normalising a genuine range of encounter types — some slow and highly present, some quick and functional, some exploratory, some that don't fully work and are simply left there without a post-mortem. Couples who build in this range tend to report less anxiety around initiation, because no single encounter is being asked to represent the whole relationship's sexual health.
A third, and one that connects to a theme we've covered before in the context of couple communication, is talking about expectations directly rather than each partner privately measuring the relationship against an unspoken, unrealistic standard. We wrote about the broader mechanics of this in how to talk about sex with your long-term partner without it feeling like a review — good enough sex gives that conversation a genuinely different, less loaded starting point than "are we doing this right."
Who this model is for
Good enough sex is not a framework for couples with no sexual connection at all, and McCarthy is clear that it sits alongside, not instead of, addressing genuine issues like unresolved pain, significant desire discrepancy, or unaddressed relational conflict. It is specifically aimed at couples with a workable sexual relationship who have nonetheless made themselves miserable chasing a standard that was never realistic to begin with — which, going by how many couples describe exactly that experience, is a very large group.
For that group, the shift the model offers is less about technique and more about permission. Permission for sex to be ordinary sometimes. Permission for an encounter to be fine rather than transformative. Permission to stop auditing the relationship's health against a highlight reel that was never an honest baseline in the first place.
Where this sits next to desire discrepancy
It's worth being precise about what good enough sex does and doesn't address, because it is sometimes mistaken for a solution to mismatched desire between partners rather than what it actually is: a reframe of the standard being aimed for once a couple is having sex at all. A couple with a genuine, persistent desire discrepancy — one partner wanting sex considerably more or less often than the other — needs to address that gap directly; a more forgiving definition of what counts as a good encounter doesn't resolve a frequency mismatch on its own. We've covered that distinction in more depth in low desire or desire mismatch? The difference most couples never learn.
Where the two do intersect usefully is in how the discrepancy conversation goes. A couple negotiating different desire levels under a great-sex standard is negotiating a much higher-stakes, more fraught exchange — every encounter either partner agrees to now carries the weight of needing to be worth it. Under a good-enough standard, that same negotiation has more room in it, because neither partner is on the hook to deliver or receive something extraordinary just to make participating worthwhile.
The relief in lowering the bar correctly
There is a specific kind of relief couples describe once this reframe lands, and it is worth naming precisely because it so often gets mistaken for resignation from the outside. Lowering the bar from "great, every time" to "good enough, most of the time, with room for great and room for off nights" is not giving up on a satisfying sex life. It is replacing an impossible standard with an achievable, genuinely sustainable one — and sustainable is what long-term desire actually needs, far more than it needs intensity.
Good enough sex asks less of any single night and more of the ongoing, honest closeness between two people. acoupl is built as a private space for that kind of low-pressure, ongoing connection. Join the waitlist.
