Previous research has examined the phenomenon of “sexual fluidity,” but there is no current consensus on the specific meaning and operationalization of this construct. The present study used a sample of 76 women with diverse sexual orientations to compare four different types of sexual fluidity: (1) fluidity as overall erotic responsiveness to one’s less-preferred gender, (2) fluidity as situational variability in erotic responsiveness to one’s less-preferred gender, (3) fluidity as discrepancy between the gender patterning of sexual attractions and the gender patterning of sexual partnering, and (4) fluidity as instability in day-to-day attractions over time. We examined how these four types of fluidity relate to one another and to other features of women’s sexual profiles (bisexual vs. exclusive patterns of attraction, sex drive, interest in uncommitted sex, age of sexual debut, and lifetime number of sexual partners). The four types of fluidity were not correlated with one another (with the exception of the first and fourth), and each showed a unique pattern of association with other features of women’s sexual profiles. The only type of fluidity associated with bisexuality was overall erotic responsiveness to the less-preferred gender. The findings demonstrate that future research on sexual fluidity should distinguish between its different forms.
