Many members of the queer community, even people who themselves are under the Multisexual Umbrella, are unaware of the Multisexual identities outside of Bisexual. This is a list of the most common Multisexual identities and what they mean.
Multisexual is both an Umbrella Term, a term used to describe a more broad group of people or ideas, and a less specific Multisexual identity.
Bisexual is the most well known Multisexual identity, and is often thought of as only describing attraction to men and women, but Bisexual can be used to describe feelings of sexual attraction to any combination of two sexes, genders, or gender expressions. For example, someone who is attracted to both men and agender people could still label themselves as Bisexual.
Polysexual people experience sexual attraction to more than two, but not all, sexes, genders, and gender expressions. One of the combinations a Polysexual person could be attracted to could be women, demiwoman, and androgyne people.
Omnisexual people are attracted to all sexes, genders, and gender expressions, but still consider themselves to be influenced by these things and often have a preference for some over the others. An Omnisexual may be sexually attracted to all combinations, but still prefer nonbinary partners over men or women.
Pansexuals are the second most well known and most common kind of Multisexuals. They are attracted to all sexes, genders, and gender expressions, and don’t consider any of these things to influence their sexual preference. A common saying used by Pansexuals is “Hearts not Parts!”
Please keep in mind that this is not at all an exhaustive list, and there are many more less common and more specific Multisexual identities. However, these are the most common ones and the ones that you are going to run into with the most frequency.
