I am polyamorous. I’m pretty new to it, but I already realize that if you ask five different people what their definition of polyamory is you will get five different answers, lol. This definition fits for me: "Someone who intentionally and openly creates multiple love-based relationships that may or may not include sex." For me, it means having deep, meaningful love relationships with more than one person. It means that I don't have to limit my affection for people. I can be affectionate in whatever way seems natural and appropriate and not have that destroy the other relationships that I am in.
Also, I feel like I have to include a disclosure that I'm not on OKC looking for hook-ups. Some people will read that I study sex and am Polyamorous and misinterpret my priorities.
Update: June 2013
I do not have a primary partner right now and would love to find one who lives near me, that is what I am looking for. Until that person comes along, I am open to allowing all new relationships to form organically into whatever definition we decide they are meant to fit.
