Bi Definition Bisexuals are people with the (some include “inborn” or “innate”) capacity to form enduring physical, romantic, (some include “spiritual”) and/or emotional attractions to:
(1) those of the same/similar sex and/or gender as themselves
(2) those of different sexes, genders/gender presentations from themselves.
There may be an individual attraction for one sex/gender or gender presentation which can also be fluid and changeable over time.
Being Bisexual/(Biromantic) is not synonymous with being polyamorous (some include “or promiscuous”). Individual bisexual people may be celibate, monogamous or non-monogamous just as individual straight, lesbian, asexual or gay people can be.
No matter what their own sex, gender/gender presentation or the sex, gender/gender presentation of the person they are partnered with, bisexual people remain bisexual. They do not suddenly switch orientation when they enter into a relationship.
