polyamoury: "the practice, desire, or acceptance of having more than one intimate relationship at a time with the knowledge and consent of everyone involved.
This is different from swinging (only open sexual relationships), or polygamy (many wives), or polyandry (many husbands).
While wikipedia-surfing today, I came across a new concept: "compersion": "a state of empathetic happiness and joy experienced when an individual's current or former romantic partner experiences happiness and joy through an outside source, including, but not limited to, another romantic interest... often referred to as "the opposite of jealousy". And I thought that this concept links nicely with utilitarianism:
compersion: whenever a partner gains happiness, let's not be jealous that it did not come from our relationship
utilitarianism: whenever anyone gains happiness, it doesn't matter what social relationship you bear to that person or what causal relationship you bear to that happiness, it's still valuable.
What do you think about polyamoury?
