Hey my name is Richie. My girlfriend recently joined the boards. Her intro topic was http://www.polyamory.com/forum/showthread.php?t=4167
Anyhow, her and I have been together for just over two years now. I also read a book on polyamorous lifestyles when we first dating because I was pretty into the idea; I felt like something in me agreed with this type of lifestyle over monogamy... but that the biggest obstacle would be getting over my own insecurities. We have been polyamorous more in theory than in practice. (This is mainly due to us not knowing many people who feel the way we do).
It looks like this forum will be pretty insightful and active. I'm excited to be on board!
