When I was 53, I met a young woman in her 30's and she told me about poly. It was the first time I had ever heard the word. That was in November 09 and by May 2010 I was active in the lifestyle.
The reason poly works for me is because I get to do poly and work it in a way that is comfortable for me. I love relationships ......and lots of them. But- I don't really care to see someone every day. I don't mind talking to my SO every day, but I'd prefer not to have to see someone or a group of people every day. Seeing people too often spoils the connection I have with them- that's just me. And it can make me feel trapped.
I also don't want to feel obligated that I have to be with someone or a group of people every weekend.
I like variety and change. I will always cycle back to each of my lovers and I like it to happen naturally.
The key to life is in being fully engaged and peacefully detached simultaneously and authentically in each moment.
