What Is Pansexuality—And How Is It Different From Bisexuality?
In use since the s, the term is an adaptation of the initialism LGB , which began to replace the term gay in reference to the broader LGBT community beginning in the mid-to-late s. It may refer to anyone who is non-heterosexual or non- cisgender , instead of exclusively to people who are lesbian, gay, bisexual, or transgender. Longer acronyms, with some being over twice as long as LGBT , have prompted criticism for their length,    and the implication that the acronym refers to a single community is also controversial. The first widely used term, homosexual , now carries negative connotations in the United States.
Bisexuality is romantic attraction, sexual attraction , or sexual behavior toward both males and females,    or to more than one sex or gender. The term bisexuality is mainly used in the context of human attraction to denote romantic or sexual feelings toward both men and women,    and the concept is one of the three main classifications of sexual orientation along with heterosexuality and homosexuality , all of which exist on the heterosexual—homosexual continuum. A bisexual identity does not necessarily equate to equal sexual attraction to both sexes; commonly, people who have a distinct but not exclusive sexual preference for one sex over the other also identify themselves as bisexual. Scientists do not know the exact cause of sexual orientation, but they theorize that it is caused by a complex interplay of genetic , hormonal , and environmental influences ,    and do not view it as a choice. Bisexuality has been observed in various human societies  and elsewhere in the animal kingdom    throughout recorded history.
