Wow! That made me tired just reading it, I can't even imagine living it. Thank you for sharing that and thank you for educating me. And, as always, I very much appreciate your humor.
I feel like my first exposure to poly was through the book Stranger in a Strange Land by Heinlein. One of my favorites that I reread every year or two. He didn't label it as such, but the main character (a human raised on Mars by Martians) expressed physical love in a way that seems to be on par with what I've read about your lifestyle.
This time around the wheel of life, I fear that my insecurities would preclude my ability to truly embrace it. To me, the heart it would require is bigger than mine.
