Don’t Do Unto Others
Don’t Do Unto Others By William Saletan, a Slate article on polyamory. Best quote from the article:
Fidelity isn’t natural, but jealousy is. Hence the one-spouse rule. One isn’t the number of people you want to sleep with. It’s the number of people you want your spouse to sleep with.
I don’t believe that’s 100% true for everyone, but it seems to be true for a lot of ’em, including the “I’m cool with it,” ones.
