Poly Definitions

There are many unusual words used by Poly people and as far as we known there isn't a definitive dictionary. However here is a collection of definitions Bob Miller has collected from several places plus some of his own.


Poly Short for polyamorous, usually used as an adjective. A Poly relationship is a non- monogamous relationship. A Poly person is someone in, or at least interested in, a Poly relationship. See polyamory. (2)

Polyamory Literally, "many loves". A generic term for non-monogamy, with a heavy emphasis on honesty and responsibility. (2)

Polyfidelity Closed relationship involving more than two people. The members of a group marriage, for example, may limit their sexual/romantic involvement to members of the group. They could then be described as polyfidelitous. (2)

Serial Monogamy The most common style of relating in the US today. The belief that a person should only have one lover at a time. This is belief is so strong that millions of people end perfectly good relationships in order to start another. (1)

Monogamy A closed two person hetro relationship, may be the result of an informed mutual agreement or from not understanding that there are viable options.

Safe Sex Also known as safer sex. Ways of being sexual while trying to minimize the odds of contracting STDs (sexually transmitted diseases), particularly AIDS. This is done by minimizing the exchange of bodily fluids (especially semen, vaginal secretions, and blood), usually by using latex barriers such as condoms and dental dams for intercourse and oral sex, and/or by limiting sexual practices to less risky ones (e.g. mutual masturbation). (2)

Sex Negative An adjective used to describe people who think of sexuality in general (and/or any sexuality different from their own) as dirty or distasteful. (2)

Sex Positive An adjective often used to describe people who are comfortable with their own sexuality and sexuality in general. (2)

Swinging The practice of having sex with others where the focus is primarily sexual. Often done in groups. Sex is an important part of the poly lifestyle and many are swingers as they have a sex positive bias and are open to all forms of responsible, consensual relating. (1) A sub-culture of people who enjoy being sexual with acquaintances and/or friends. This word seems to be a point of some contention. Many people happily self-identify as swingers, many others reject that in favor of "poly", which is more generic. Some self-identified Poly people associate "swinging" with sexist, indiscriminate, dishonest, and/or risky sexual behavior. The truth is probably that behavior like this probably does or doesn't happen no matter what the participants call themselves. (2)
