I really wish you wouldn't say that. How can wanting to express your authentic being be greedy? It's one of those words that people who don't understand non-monogamy love to throw around, as a way to disparage it, but it's actually kind of a pointless barb. There's no law that any of us has to do life the way society has taught us is acceptable. You only have to suit yourself and your partner - and it sounds like you've found a way to do that. Brava!
