Do Couples Need to Match in Desire? A 366-Couple Study Says Overall Level Matters More
Researchers at Western University and collaborating universities found no unique benefit of matching, and advise couples to manage differences or raise desire
The Question
A staple of sex therapy advice holds that couples whose sexual desire is out of step are at risk. The idea is simple: if one partner wants sex more often than the other, both are likely to feel frustrated. A study in Social Psychological and Personality Science set out to test whether the assumption holds when examined with a more detailed method.
PsyPost reported the study, titled “Are Couples More Satisfied When They Match in Sexual Desire? New Insights From Response Surface Analyses.” The authors are James J. Kim, Amy Muise, Max Barranti, Kristen P. Mark, Natalie O. Rosen, Cheryl Harasymchuk and Emily Impett. Kim is a postdoctoral fellow at Western University and a member of the Relationship Decisions Lab.
The Method
The study included 366 heterosexual couples. Each partner individually completed assessments of sexual desire, relationship satisfaction and sexual satisfaction. Earlier studies had measured desire mismatch by subtracting one partner’s score from the other’s. That approach treats a couple where both partners score low as identical to a couple where both score high.
Kim and colleagues used dyadic response surface analysis instead. It lets researchers test whether satisfaction is higher for matched couples than for mismatched couples at every level of desire, separating the effect of matching from the effect of how much desire each partner has.
What They Found
There was no evidence that matched couples were more satisfied than mismatched couples. As Kim put it, “there was no unique effect of matching.” The most important factor appeared to be the overall level of desire. In Kim’s words, what matters is “partners having higher levels of sexual desire.”
This is a modest but significant shift in emphasis. It does not say mismatch is harmless. It says that, in this sample, once the level of desire is taken into account, similarity added nothing further. The PsyPost summary gives no effect sizes or other statistics, so the strength of the results cannot be assessed from it.
A separate study reported by PsyPost in 2022 points the same way. Researchers led by Atia Attaky studied 100 heterosexual couples in Saudi Arabia and found that higher desire in either partner was associated with better sexual function, sexual satisfaction and relationship satisfaction. Half of that sample was recruited from people seeking help at an outpatient psychiatric centre in Riyadh, and the design was cross-sectional, so it cannot show causation.
Practical Implications
Kim suggested that couples may do better by managing differences, for example by communicating well when desire is low, or by working to boost desire, rather than trying to make their levels more alike. That is a change from advice that frames the aim as convergence.
For therapists, the implication is that the goal is not necessarily to find a midpoint between a high-desire partner and a low-desire one. It may be to understand what lowers desire for either partner, such as stress, sleep, health, mood or conflict, and to address those.
For couples, the finding offers some reassurance. Differences in desire are common, and the data do not show that they doom a relationship. They also suggest that the quality of communication about the difference deserves as much attention as the difference itself.
Why the Method Matters
Statistical method can change a conclusion. When researchers reduce a couple to a single difference score, they discard information, since a gap of two points between partners looks the same whether the couple sits at the bottom or the top of the scale. Response surface analysis keeps both partners’ scores in the model and asks whether the pattern of satisfaction changes across the whole range. The result in this case was that the old finding of a mismatch penalty was not supported.
That is a useful reminder that clinical rules of thumb should be revisited as methods improve. It is also a reason to be cautious about a single study. A different sample, a different measure of desire or a longer follow-up could produce a different picture, and replication by independent teams will be the real test.
The Limits
Desire in the study was measured as self-reported trait sexual desire, so matching was judged on those scores. Partners’ perceptions of desire discrepancies were not assessed. Kim notes that people may perceive discrepancies that do not exist, and may miss ones that do. He also cites earlier work finding that perceived discrepancies predict lower satisfaction more strongly than actual discrepancies do.
That point deserves emphasis. If a partner believes there is a mismatch, that belief may affect satisfaction whether or not it is accurate. Talking directly about what each partner wants may therefore matter more than any measured score.
The sample was heterosexual couples, so results may not apply to same-sex couples or to relationships with other structures. Readers should look to further studies and to individual guidance from a qualified clinician.
