Research indicates that women are more likely than men to pursue same-sex relationships later in life due to sexual fluidity, a phenomenon where sexual attraction and identity shift over time. According to psychophysiologist Nicole Prause, women are more likely to alter their reported sexual orientation based on circumstance, whereas men often show higher resistance to changing their identity through intimate behavior alone. Experts attribute this trend to a combination of social acceptance, hormonal shifts, and evolutionary adaptations.

Why Does Sexual Fluidity Affect Women More Than Men?

Sexual fluidity, a term popularized by psychologist Lisa Diamond in 2008, describes the capacity for one’s sexual attraction to change over time. After a decade-long study of 100 women, Diamond found that unlike rigid sexual orientations, many women experience a “fluid” state where they may update their identities to reflect new attractions. Nicole Prause notes that while men tend to select a sexuality and remain firm in that identity, women act as “wildcards,” making them more prone to shifting their preferences throughout their adult lives.

The Role of Biology and Hormones in Relationship Shifts

Some researchers suggest that biological factors may influence this increased fluidity in midlife. Sheryl Kingsberg, a professor of behavioral medicine at University Hospitals Cleveland Medical Center, reports seeing a “mild increase” in women in their 30s transitioning toward same-sex relationships. Kingsberg suggests this could be linked to an epigenetic shift in brain chemistry or hormonal changes. Elevated testosterone levels, which can increase with age, have also been linked to higher incidences of same-sex attraction, according to emerging psychological theories.

Is Fluidity a Biological Reality or a Social Construct?

While biological theories exist, many experts argue that the disparity between men and women is largely social. Clinical social worker Alisha Powell suggests that men may possess the same capacity for fluidity as women, but societal stigma prevents them from acting on it. In Western cultures, women often face fewer social consequences for engaging in same-sex relationships, allowing them more freedom to explore their changing desires. This contrast suggests that the higher reported rates of fluidity in women may reflect a safer environment for self-expression rather than a fundamental biological difference.

Common Questions About Sexual Fluidity

Does sexual fluidity mean someone is bisexual?

Not necessarily. Lisa Diamond’s research distinguishes between bisexuality—an attraction to both genders—and sexual fluidity, which is the potential for one’s orientation to change or evolve regardless of how one previously identified.

Is infidelity the primary driver of these shifts?

No. Experts emphasize that fluidity is rarely the sole cause of a relationship ending. Most divorces involving this transition follow deeper, pre-existing relationship issues, with sexual exploration acting as a catalyst for change rather than the root problem.

Can men be sexually fluid?

Yes. Experts like Alisha Powell suggest that men likely have the same biological potential for fluidity as women, but that cultural expectations and social costs often suppress these expressions in men.
