A spectrasexual is a term used to refer to a person who is able to be romantically and/or sexually attracted to a wide range of individuals, including those of different sexes, genders and gender expressions - but not necessarily all of them. It is important to note that the exact definition of spectrasexual varies. However, it is noted as being distinct from pansexuality and omnisexuality.
Spectrasexuality is considered to be a sexual orientation, although it is a less common one for people to identify with. Because most people believe that sexual orientation exists on a spectrum, labels for various orientations help people identify where they feel they fit on that spectrum and communicate it to others.
