Multisexual

Multisexuality (also known as plurisexuality) is an umbrella term for any form of attraction to more than one gender. It is synonymous with m-spec (multisexual spectrum), along with all other terms that broadly describe attraction to multiple genders (i.e. pluralian, bisexual, etc). It can describe people who are pansexual, polysexual, omnisexual, etc, or can be used as a stand-alone identity if one does not wish to specify their sexuality further.

The opposite of multisexual is monosexual. The romantic counterpart to multisexual is multiromantic.

Multisexual vs. Other Terms
Multisexual or m-spec includes terms to describe all sexualities attracted to multiple genders. Some people have pushed for "bisexual umbrella" to be used instead of multisexual, however this push was largely started by m-spec exclusionists, and so the use of "bisexual umbrella" can often come with the implication (intentional or not) that one sees other terms as "just bi" or that "no other terms are needed other than bi", even though bisexuality and multisexuality are synonymous in their definitions.

Many m-spec people who don't identify as bisexual do not want their identity watered down to "a subtype of bisexual". These people commonly identify with terms other than bisexual because those different terms often allow them to communicate their personal experience of attraction with more accuracy. While some people who use other labels do identify as bisexual in addition to that other label, other people do not connect to the label bisexual and don't feel comfortable using it. They would prefer being the sexuality they are, rather than being forced into a label they do not identify as.

Using multisexual as an umbrella term may also allow for all groups to have unifying term while also having separate communities. M-spec people who don't identify as bisexual may not have to feel like an after thought in things labeled as bisexual, and bisexual communities can have their own history and community. Additionally, it may allow for more visibility of various m-spec identities. This is not to say that using bisexual as an umbrella can't achieve these same things, just that multisexual tends to be the preferred label as many m-spec individuals unfortunately no longer feel safe within bisexual communities.
