Hi from GA
We are a married couple that recently (august) decided to add another person in the bed. Before we knew it, our feelings changed a bit and we mutually agreed that we did benefit from our experience and decided to try to make a relationship with a third. At the time, we had never heard of polyamory.
We are currently in a triad with another male. While he and I do not label ourselves bi (or any other label), we do have a level of intimacy. He and I both have deeper intimacy with her. It has been interesting to let ourselves be free in the moment and allow ourselves to have feelings for another person, while discovering things about ourselves and breaking the constraints of our own previously adapted labels.
My wife and I spoke last night at length about our new life and we don't plan on looking back. Our secondary has plans to move on one day and while it may be painful, we will have learned and enjoyed the time. I landed here not for personals so much, as just a chance to network and learn about new possibilities.
