Bigender
Bigender is characterized as having both male and female gender expression. Some bigender people may have predominantly male expression, while some may have predominantly female expression. Then again, some may even have almost even expressions between male and female. It's also very important to remember that bigender people don't necessarily present as a mix of male and female. Many actually present as the one gender that they most feel like at that specific time. Sometimes, they will present as both, or even a mix of many genders. Bigender is different from androgyny, in that bigender people typically change their behaviors to math their gender, androgynous people retain the same gender-neutral behaviors throughout.
