A new study suggests that couples who are on the same page about physical affection report higher relationship well-being, with the effect strongest when they are in private spaces. The research analysed responses from more than 1,800 individuals in romantic relationships and examined both average comfort with touch and perceived differences between partners.
Physical touch between romantic partners is linked to a range of physiological and psychological benefits. Activities such as holding hands, hugging and kissing can reduce stress, support immune function and foster a sense of security. Touch is known to improve cardiovascular functioning and trigger the release of oxytocin, a hormone involved in social bonding.
Conversely, when people desire more affection than they receive, they can experience affection deprivation, a state frequently associated with relationship dissatisfaction and feelings of distance from a partner. An unfulfilled desire for touch is linked to tension and inhibited communication.
Psychology researchers Sabrina Sgambati, Diane Holmberg and Karen L. Blair sought to understand how variations in comfort with physical affection relate to a couple’s happiness. They examined whether average comfort levels and discrepancies between partners could predict relationship well-being, noting that a shared sense of reality can reduce constant negotiation and lessen conflict.
The team also asked whether these dynamics shift depending on setting. Public spaces bring social pressures absent in private ones, and some individuals may prefer affection in private but feel awkward around family, friends or strangers.
The contextual difference is particularly relevant for same-sex couples, who may experience marginalisation and heightened vigilance around public displays of affection, potentially altering how public touch relates to relationship satisfaction.
To explore these questions, researchers analysed survey data from 1,832 individuals in romantic relationships. Participants rated their own comfort with affection and how comfortable they believed their partner was, twice—once for private settings and once for public ones.
The researchers calculated an average perceived comfort score for each couple and a score representing the gap between a participant’s comfort level and their partner’s presumed comfort. They then compared these affection scores with self-reported relationship quality, which included trust, intimacy, passion and overall satisfaction.
Higher average comfort with physical affection consistently predicted better relationship well-being, for both private and public settings. When both partners were perceived to be highly comfortable with touch, the relationship tended to be stronger.
Disparities between partners mattered too. Larger perceived gaps in comfort were linked to lower relationship well-being, especially in public settings once average comfort levels were accounted for. If one partner felt very comfortable with touch and believed the other was uncomfortable, satisfaction tended to be lower.
The environment influenced the strength of these associations. Feeling strongly comfortable sharing affection in private was more closely tied to strong relationship well-being than comfort in public. The researchers suggested that as long as couples can connect in private, public discomfort can be attributed more to personal decorum or cultural norms than to a lack of affection.
When comparing mixed-sex and same-sex relationships, the overall patterns were largely similar: higher comfort levels and smaller gaps generally aligned with better relationship quality. The underlying mechanics appeared similar across gender groups.
Some differences emerged. Individuals in same-sex relationships reported lower average comfort with public affection and perceived larger gaps between themselves and their partners in public settings. The researchers linked this to ongoing social stigma and safety concerns faced by some same-sex couples.
Additionally, same-sex couples maintained slightly higher relationship well-being than mixed-sex couples when average private affection comfort was low. The researchers suggested that same-sex couples, who frequently restrict public affection for safety, may develop alternative, non-physical ways to express love that carry into private settings, reducing the centrality of touch to overall satisfaction.
A second dataset, comprising 86 couples, allowed for a direct dyadic analysis comparing both partners’ scores. The results largely mirrored the initial findings: higher actual average comfort with private affection predicted better relationship well-being, and alignment in private comfort remained a strong indicator of a happy relationship.
Actual discrepancies in public comfort levels were not associated with relationship well-being. Likewise, actual average comfort in public failed to predict better relationship quality when other variables were considered, suggesting that what a partner believes about the other’s comfort may matter more than the partner’s own self-reported level.
The researchers note that this divergence points to a potential difference between perceived alignment and actual alignment, with mutual comfort likely reinforcing each other over time. They also acknowledge limitations, including the smaller dyadic sample which may have limited power to detect subtle effects and the exclusion of gender-diverse relationships from the analysis.
With these caveats, the study—“In Sync? Assessing Partners’ Similarities in Comfort With Physical Affection–Sharing as a Predictor of Relationship Well-Being”—was authored by Sabrina Sgambati, Diane Holmberg and Karen L. Blair.
