Sexual fluidity in young adult women and men: associations with sexual orientation and sexual identity development

This research investigated sexual fluidity in attractions and sexual identity and associations with sexual orientation dimensions and sexual identity development in 199 (124 female, 75 male) US sexual minority young adults, ages 18-26 years. Participants completed an online questionnaire measuring sexual fluidity in attractions and sexual identity, sexual orientation dimensions (sexual identity, attractions, sexual behaviour) and sexual identity development. Sexual fluidity in attractions was reported by 64%of women and 52% of men, with 49% of those women and 36% of those men reporting sexual fluidity in sexual identity based on experiencing changes in attractions, with no significant gender differences. Sexually fluid women used a range of sexual identities, whereas most sexually fluid men identified as completely homosexual/gay. Sexually fluid people were more likely than non-sexually-fluid people to have engaged in past sexual behaviours with both genders. Sexual fluidity in attractions was not related to the timing of sexual identity developmental milestones; however, women reached some milestones at a later age than men. Findings from this research shed light on the complexities of sexual fluidity and sexual identity development in both women and men.
