Pansexuality  is a popular term referring to the feeling that one has the potential for sexual attractions, sexual desire, or romantic love, towards people of all gender identities and biological sexes. Some self-identified pansexuals 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 practice.Pansexuality can also mean the attraction to a person's personality, rather than their physical appearance or gender.

The concept of pansexuality deliberately rejects the idea that there are only two genders, as pansexual people are open to relationships with people who do not identify as strictly men or women.
