Polyamory
Polyamory (from Ancient Greek πολύς (polús) 'many' and Latin amor 'love') is the practice or support of, maintaining committed, romantic, and/or sexual relationships with more than one partner, in parallel or concurrently, with the consent of all involved partners. Polyamory allows for ethical-non-monogamy (ENM), which is a subset of the broader consensual non-monogamy.
