I guess it all depends. :) If you don’t already know, I’d start by figuring out what you want from polyamory. There are a lot of configurations and needs/wants different people have. i.e. some people really like getting to know lots of new people in an intimate way. Others are in it mostly for the sex. Others (like me) are really happy in long-term multi-partnered stable committed relationships, with the possibility for openness in outside secondary relationships. I didn’t start out wanting that, but after a few years of dating in casual relationships, I made stability a goal, and then got really lucky. :)

Knowing yourself really well is important, because negotiating and communicating with poly partners isn’t always easy. Knowing yourself really well is a good step towards this.

There’s a good book called The Ethical Slut. That’s a good place to start learning about it, as well as hundreds of sources online. The FAQs on polyamory.org is good, too: http://www.polyamory.org/

Let me know if you have any more questions. :)
