I'm glad you shared that 'more than two' website. I had not yet seen it linked within this forum yet either. Even though I have been sailing the poly seas for about six years now, I still second guess myself at everything and I don't feel like it's an old easy habit. And when I look at websites or articles new to me I can usually find at least one new thing to help me and my partnerships.
Somewhere in my intro thread I said my dream poly goal would be cohabitation with my two partners. That's what I want, and of course I hope to reach that one day, but unless everyone feels ok about it, it won't happen. The point I'm at right now is that I've brought up the idea and some ways to achieve it, and I am letting my two partners stew on it. also, getting their feedback when they have any.
Your task is to acknowledge to yourself and others that every part of you has a right to exist.
