Polysexuality refers to people who are attracted to more than one gender or sex but do not wish to identify as bisexual because it implies that there are only two binary genders or sexes. Polysexuals are those people sexually attracted to many different sorts of ideas and characteristics. Polysexuality should not be confused with pansexuality; pan meaning all, and poly meaning many, though not necessarily all.

The term is sometimes confused for "polyamory," which is a term for relationships that are non-monogamous.

Polysexuality is a self-identifying term that is somewhat amorphous, as there is a wide variety of different people who use the term to describe themselves.
