Feeling Your Partner Is ‘Out of Your League’ May Change How You Behave During Sex

The paper, titled “Polish Women’s Sexual Strategies in Mate Retention: Initiating Sex, Faking Orgasms, and Performing Oral Sex in Response to Mate Value Discrepancy–Evidence from a Preregistered Study,” adds to a growing body of work on the subtle ways relationship dynamics influence sexual behavior.

Women in long-term heterosexual relationships who view their male partners as more desirable than themselves report a stronger motivation to satisfy them sexually. This motivation is linked to more frequent sex initiation, performing oral sex, and faking orgasms, according to new research.

The study, conducted in Poland and published in Archives of Sexual Behavior, examined how perceived differences in mate value shape sexual behavior. Mate value refers to how desirable someone seems as a romantic or sexual partner, based on traits such as attractiveness, health, status, and personality.

Why mate value matters in couples

Previous research suggests that stable romantic relationships offer emotional security, resource sharing, and a supportive environment for raising children. From an evolutionary viewpoint, long-term bonds can benefit both partners and improve children’s survival.

However, maintaining such relationships involves balancing commitment with attraction to alternatives. To protect their relationships, partners use mate-retention strategies, which can either provide benefits, such as affection and sexual satisfaction, or impose costs, such as jealousy and control.

Benefit-provisioning strategies focus on strengthening the bond by offering care, attention, and pleasure. Cost-inflicting strategies rely on pressure and restriction to prevent a partner from leaving. Feelings of insecurity may intensify when a person believes their partner has higher mate value than they do.

How the researchers designed the study

The research team, led by Natalia Frankowska of SWPS University in Poland, focused on how women respond when they see their partner as more desirable. They examined whether perceived mate value gaps predict sexual behaviors aimed at keeping a partner invested.

The study surveyed 562 Polish women aged 18 to 50 who were in committed, sexually active relationships. Most reported exclusively heterosexual behavior, while a smaller group reported predominantly heterosexual behavior. About 64% had been with their partner for more than three years.

Participants completed an online questionnaire about how often, in their last 10 sexual encounters, they initiated sex, performed oral sex on their partner, and faked orgasms. They also reported their own orgasm frequency and whether they received oral sex from their partner.

Measuring perceived mate value gap

To assess mate value discrepancy, women used a brief Mate Value Scale to rate their own desirability and that of their partner. The difference between these scores reflected whether they felt relatively less or more desirable than their partner.

Participants also rated their motivation to sexually satisfy their partner and their perceived vulnerability to disease. This allowed researchers to test whether concerns about health or personal enjoyment of oral sex influenced the patterns they observed.

The team predicted that women who saw their partner as having higher mate value would be more motivated to please him sexually. They further expected that this motivation would translate into more frequent sex initiation, fellatio, and faked orgasms.

Key findings on women’s sexual behavior

Women who rated their partner’s mate value higher than their own tended to report slightly greater motivation to satisfy him sexually. In turn, women with stronger motivation were somewhat more likely to initiate sex, perform oral sex, and fake orgasms.

Importantly, mate value discrepancy did not directly predict these behaviors. Instead, the effect appeared indirect: feeling less desirable increased the drive to please a partner, and this motivation was associated with specific sexual actions.

The study also found that younger women generally reported higher motivation to satisfy their partners. However, the association between perceived mate value gap and motivation held even when age was taken into account.

Oral sex and enjoyment not closely linked

The researchers further tested whether enjoyment of oral sex or beliefs about a partner’s enjoyment changed the results. Among women, the indirect link between mate value discrepancy and performing fellatio did not depend on either factor.

This contrasts with earlier work by the same team on men’s behavior. In that study, the effect of mate value gap on cunnilingus was strongest among men who enjoyed performing oral sex on their partners.

The current findings suggest that while both men and women may use sexual behavior to retain desirable partners, the psychological mechanisms behind those behaviors are not identical across genders.

Limitations and implications for relationships

The authors caution that their data are correlational and based solely on self-reports about sensitive topics. Memory errors, social desirability, and cultural norms regarding sexuality may all have shaped how participants responded.

Because cause and effect cannot be established, it remains unclear whether perceiving a partner as more desirable drives these sexual behaviors, or whether existing relationship patterns influence how partner value is perceived.

Most of the observed statistical relationships were weak, meaning that many other factors, such as relationship satisfaction, attachment style, or fear of infidelity, are also likely to play important roles.

What the study means for couples

Frankowska emphasized that the findings should not be taken to mean that women’s sexual behavior is only or mainly about keeping a partner. Sexual acts can simultaneously express desire, affection, pleasure, and security, and their meaning can vary across couples.

The results point instead to one possible psychological mechanism: when a woman feels her partner is particularly desirable, she may, often unconsciously, invest more effort into making him feel sexually satisfied.

The researchers plan to explore how these processes work in different cultures and under what conditions sexual behaviors more clearly function as mate-retention strategies. Such studies could help clarify how perceptions of value and security shape intimacy over time.
