Monogamy or polygamy?

Question

Answer

There are two standard definitions of monogamy, but only one for polygamy, so this is hard to answer as presented.

The first definition of monogamy is to be married to only one person  (as opposed to polygamy, which includes multiple spouses). Using this definition, I'm in a monogamous marriage.

We tend to use the second definition, however, which refers to sexual or romantic exclusivity. Based on this definition, my marriage is not monogamous. We allow for additional sexual partners. We aren't exactly polyamorous, because that term usually assumes a romantic connection to additional partners, and it's more of a sexual or friends-with-benefits arrangement when we bring someone else into the equation, but we generally identify as non-monogamous.

Answer

It's POLYAMORY. Polygamy is a totally different thing.
