A relationship style in which a person shares sex and/or romantic love with one other person. Most commonly, monogamy is practiced by couples that are exclusively sharing sex and romantic love with each other. There are relationships in which one partner practices monogamy, while their partner practices some form of non-monogamy.


Novogamy is term coined by Dr. Jorge Ferrer in his book, Love & Freedom: Transcending Monogamy and Polyamory. Ferrer frames mono/poly as a relationship style binary, similar to the traditional male/female gender binary. Ferrer then describes moving beyond the mono/poly binary as a novel and plural relational field called novogamy. Novogamy is similar to relationship anarchy.
