Bigender

Bigender (bi+gender) is a tendency to move between masculine and feminine gender-typed behaviour depending on context, expressing a distinctly "en femme" persona and a distinctly "en homme" persona, feminine and masculine respectively. It is a subset of transgender.

While an androgynous person retains the same gender-typed behaviour across situations, the bigendered person consciously or unconsciously changes their gender-role behaviour from primarily masculine to primarily feminine, or vice versa.

Use of Term
It is worth noting that this concept emerged from within the transgender community itself, rather than being adopted after it was created by another sub-culture (for example, transsexual was defined first by the mental health community).

Because bigender is still a self-applied label, it is not possible to give a definitive outline of the typical bigender. Any description of a bigender is just an example of what someone who identifies as bigender might be like. Although there are patterns, the only firm characteristic is the sense of dual gender.

Expression
Some express their bigender identity through crossdressing or performing as a drag king/drag queen; others may adopt a strictly masculine, feminine, or androgynous appearance and experience the shift between genders on a purely mental, or only subtly physical, level.

Bigender and Sexual Orientation
It might seem that a bigender identity must go with a bisexual identity but gender identity and sexual orientation are independent. It is possible to be bigender and not bisexual, or bisexual but not bigender.

For some bigenders, labels like gay, lesbian or bisexual can seem less relevant or satisfactory due to their focus on physiological sex. Some might prefer terms that refer to gender (see Gynephilia and androphilia) while others might prefer to not specify a sexual orientation at all. Since bigender is a gender-related term, not an erotic one, a bigender can of course be asexual.

Bigender in Popular Culture
While performers such as David Bowie and Boy George are known for combining masculine and feminine aspects, performers who switch between a primarily masculine or feminine image, such as Eddie Izzard and Annie Lennox, better fit the bigender label. It is good to keep in mind, however, that crossdressing is not always related to gender identity, as it can be a purely erotic act.
