"Bisexual (often shortened to Bi) refers to someone who is attracted to two or more genders. It is also sometimes worded as the attraction to genders both the same as and different than one's own. This is most commonly understood to mean men and women, although bisexual activists have been outspoken about the fact that it is not limited to the gender binary. Bisexual people can be attracted to any genders and can be attracted to any number of genders, anywhere from two genders to all genders. Bisexual people may or may not have a preference and may or may not feel a difference between genders."
