The term "polysexuality" is defined by attraction to many genders and identities. Someone who is polysexual can consider themselves a member of the LGBTQ + community, as polysexuality is a "queer" identity.
Identifying as polysexual means that a person is not necessarily attracted to all genders, but many genders.
Polysexuality also has nothing to do with polyamory, which is a relationship style, not a sexuality. Polyamory is "a form of consensual non-monogamy that emphasizes the emotional connection between multiple partners."
People who identify as polysexual simply have more individual and specific preferences - and their identity reflects that. The term also applies to the fact that sexuality is deeply personal. In other words, polysexuality looks different for each person who identifies as such.
For example, being polysexual can mean attraction to all genders except transgender men. It can also mean attraction only to people who have a male presence or appearance, regardless of his gender.
The prefix "poly" means "many" and if you are attracted to people of different genders, then you are polysexual.
