Pansexuality (also referred to as omnisexuality or polysexuality) refers to the potential for sexual attractions, sexual desire, romantic love, or emotional attraction, towards people of all gender identities and biological sexes. Self-identified pansexuals may refer to themselves as gender-blind—that gender and sex are insignificant or irrelevant in determining whether they will be sexually attracted to others.
The Oxford English Dictionary writes that pansexuality "encompasses all kinds of sexuality; not limited or inhibited in sexual choice with regards to gender or activity."
The concept of pansexuality deliberately rejects the gender binary, the "notion of two genders and indeed of specific sexual orientations", as pansexual people are open to relationships with people who do not identify as strictly men or women.
Pansexuality can also mean the attraction to a person's personality, rather than their physical appearance or gender.
