Polysexuality is the attraction to multiple genders. A polysexual person is one "encompassing or characterized by many different kinds of sexuality." Authors Linda Garnets and Douglas Kimmel state that polysexual is a sexual identity "used by people who recognize that the term bisexual reifies the gender dichotomy that underlies the distinction between heterosexuality and homosexuality, implying that bisexuality is nothing more than a hybrid combination of these gender and sexual dichotomies." However, it is arguable that bisexuality does not actually enforce a gender dichotomy. Bisexual activists will often argue the "bi" part can refer to genders which are the same and genders which are different.
