More specific benefits: you can get sex more often with less scheduling disruptions You can have mutually fulfilling partial relationships that would not be sustainable if they had to be monogamous. Eg: someone can get most of their affection from you but indulge their foot fetish with someone else. Or if you simply have a different sex drive than your partner. More widespread emotional support network. If you're prone to loneliness, having more people you can connect with will help you not lean all your metaphorical weight on one person Less inhibition: depending on the rules of your polyamory you no longer have to kill your own urges when seeing someone attractive to you. This may be a downside if you want to get work done. If one or more of you is bi you get to talk about people you find hot and seducing them to your bed. This is lots of fun. Less stress: the converse of 3, you don't have to b the entire emotional support for another person.
