Biflexible is a term for someone who identifies primarily as bi, but whose identity and/or attraction is flexible. These individuals are usually attracted to two or more genders, but might experience occasional changes in the specific genders, number of genders, preference of genders, etc. that they are attracted to. In addition to bi, biflexible people may identify as gay, lesbian, pan, asexual, or other orientations depending on their current and potential attractions. Biflexible can be similar to biflux and abrosexual and is a counterpart of homoflexible and heteroflexible.
This term is often confused with bicurious, which refers to someone who may not identify as bi, but is curious in exploring a potential attraction to members of two or more genders.
