Desire for Others Can Raise Desire for a Partner, Two Experiments Suggest
Research in the journal Human Nature found that sexual desire is not exclusive to one person, challenging a common worry in long-term relationships
The Idea Tested
A common worry in long relationships is that noticing other people means desire for a partner is fading. A pair of studies in the journal Human Nature, reported by PsyPost in October 2024, tested a different possibility: that sexual desire is not partner-specific, and that interest in others and desire for a partner may rise together. The paper’s title is “Sexual Desire is not Partner-Specific.” The authors are Sierra D. Peters, Jon K. Maner and Andrea L. Meltzer.
The research uses two methods. The first is a diary study. The second is an experiment. Using both is a strength, because a diary study shows what happens in daily life while an experiment shows what can be caused.
Study One: Two Years of Diaries
The first study followed 196 individuals from 98 newlywed couples, predominantly heterosexual. Couples married fewer than four months were recruited through Facebook ads and community flyers. Participants completed daily surveys for 14 days, then repeated the exercise annually for two years, giving three waves of data.
Desire for the partner was rated on a single seven-point item. Interest in alternatives was measured with four items about fantasies, conversations and flirtation with people of the opposite sex. The researchers also collected data on sociosexual orientation, relationship length and biological sex.
On days when participants reported higher desire for their partner, they also reported greater interest in alternatives, and the reverse held too. The association persisted after controlling for sociosexuality and relationship length. The PsyPost summary does not report effect sizes or p-values.
Study Two: The Experiment
The second study enrolled 405 participants in long-term relationships, recruited through CloudResearch. They were randomly assigned to one of three conditions. One group was primed to think about desire for their partner. Another was primed with desire for an attractive alternative. A control group recalled non-sexual positive experiences. All then rated partner desire and alternative desire on a seven-point scale.
Participants primed with desire for an alternative reported significantly higher desire for their partner than controls did. Those primed with partner desire did not show a statistically significant increase in alternative desire, although results trended in that direction. The authors describe converging evidence that sexual desire is not exclusive to one’s romantic partner, and the summary states that desire for one partner may increase overall sexual motivation.
What the Findings Do Not Show
It would be a mistake to read this as advice to seek out other attractions. The studies measured self-reported desire and fantasy-level interest, not behaviour, and they did not test whether acting on interest in others helps or harms a relationship. The authors themselves note that self-report may be affected by social desirability bias, and suggest future work with implicit measures that are harder to manage consciously.
The newlywed sample is also a limitation. The first study looked at couples in the first years of marriage, when desire is typically high. The findings may not apply to couples who have been together for decades, or to those in different circumstances.
The PsyPost summary does not state the institutions of the authors, and it reports no effect sizes. Anyone using the findings in practice should read the paper.
Why It Matters for Therapists and Couples
The practical interest lies in how couples interpret their own experience. Many people take a noticing glance at another person as a sign that their relationship is in trouble. If desire is a general motivational state that can be directed at a partner, the glance may say little about the relationship and more about the person’s overall sexual motivation that day.
That does not make such thoughts irrelevant. Couples therapists still treat sustained preoccupation with alternatives, or secrecy about it, as something to be addressed. The research suggests only that the occasional presence of such interest is not, by itself, a sign of declining attachment.
It also pairs with work on how couples cope with differences in desire. A study by James Kim and colleagues of 366 heterosexual couples found that matched desire levels did not predict greater satisfaction than mismatched levels, and that the overall level of desire mattered most. Together, the two lines of research favour a view of desire as a shared resource to be nurtured, rather than a fixed quantity to be measured against a partner’s.
People with persistent worries about desire, whether their own or a partner’s, should consider speaking to a licensed therapist.

Fear of a market travels fast. The same jitters turn up in the comic dispatches on the Cebu condominium story: a Manila News report on a Mactan broker with three brochures, a London Prat account of the references demanded of British retirees (direct link: https://prat.uk/cebu-estate-agents-demand-character-references/) and a Bohiney piece on two-hour open houses.
