Bisexual

Bisexuality is an orientation in which the person experiences sexual attraction to more than one gender, sometimes worded as "two or more genders".

Some people define bisexuality as attraction to one's same gender as well as different genders, but this is not true for all bisexuals. For example, an maverique person who experiences attraction to women and to men but not to other maverique people could be bisexual without same-gender attraction. The same would apply to a woman attracted to men and some or all nonbinary genders but not other women.

Misconceptions
It is often erroneously believed that bisexual people cannot be attracted to nonbinary genders. However, this is not the case. While some bisexuals may only be attracted to binary men and binary women, other bisexuals experience attraction to all genders. This means that the definition and usage of "bisexual" has a lot of overlap with other mspec terms such as pansexual, polysexual, omnisexual, etc. All mspec people choose their label according to what feels right for them.

History
The earliest usage of "bisexual" in English dates to 1824; at this time it meant "having the organs of both sexes in one being" - i.e. intersex in modern terminology.

"Bisexual" as an adjective meaning that a person has attraction to "both sexes" dates to 1914. This was first used as a noun in 1922.

The bisexual pride flag was created by Michael Page, taking inspiration from the existing "bi-angles" symbol, and was first unveiled on December 5, 1998.
