sexual fluidity

Sexual fluidity is the capacity for sexual attraction or orientation to shift over time or across situations, rather than remaining fixed throughout life.

Someone experiencing sexual fluidity might find their attractions changing—drawn to one gender in their twenties, another in their forties, or varying by emotional context.

The concept challenges the idea that sexuality is permanently set: She describes her sexuality as fluid rather than strictly lesbian or straight.

Not synonymous with bisexuality, though the two overlap; fluidity emphasizes change over time, while bisexuality describes attraction to multiple genders at any given moment.
