性的流動性とは人間に対して使われる事柄ですか？
Essentialism, in the context of sexual fluidity, is the belief that sexual orientation and sexual desire are fundamentally biological and therefore do not change throughout life. The results of a large-scale, longitudinal study by Savin-Williams, Joyner, and Rieger (2012) indicated that stability of sexual orientation identity over a six-year period was more common than change, particularly for men. While stability may be more common than change, change in sexual orientation identity does occur and the vast majority of research indicates that female sexuality is more fluid than male sexuality. This could be attributed to females' higher erotic plasticity or to sociocultural factors that socialize women to be more open to change. Due to the gender differences in the stability of sexual orientation identity, male and female sexuality are not treated as functioning via the same mechanisms. Researchers continue to analyze sexual fluidity to better determine its relationship to sexual orientation subgroups (i.e., bisexual, lesbian, gay, etc.).
