Gender rebellion feminists suggest that, when biological sex (male or female), gender (masculine or feminine), and sexual orientation are taken into account there are really, eighteen genders, not the two that are traditionally considered appropriate in Western Society. They are:

homosexual masculine male
bisexual masculine male
heterosexual masculine male
homosexual androgynous male
bisexual androgynous male
heterosexual androgynous male
homosexual feminine male
bisexual feminine male
heterosexual feminine male
homosexual masculine female
bisexual masculine female
heterosexual masculine female
homosexual androgynous female
bisexual androgynous female
heterosexual androgynous female
homosexual feminine female
bisexual feminine female
heterosexual feminine female

Some other gender rebellion radical feminists argue, however, that this system is no better than traditional binary understanding of gender because it still catagorizes people, which limits their ability to self-actualize and be recognized as fully human.
