Happy Bisexuality Awareness Week! The celebration promotes cultural acceptance of the bisexual community and advocates for bisexual rights. A bisexual person is someone whose sexual or romantic preference includes people of two or more genders, though the attraction doesn't need to be equally strong for each gender. There are several distinct but sometimes overlapping identities too, including Pansexual and Polysexual. Some of these exist because the traditional definition of bisexuality referred only to an attraction to men and women, excluding all other genders.
