My husband and I started out as a poly couple. Although it wasn't called that back then, just non-monogamous.
I was with a woman and my husband came into our relationship... does that count? It's been 11 years now, 8 of marriage. As far as the people we have seen and see we date one person together, although quite often spend alone time with him and all the others are either mine or his to date. Poly isn't always a "triad" situation. I am in a "V" with my husband and my other primary.
Have a read on this forum a bit and you will see the wide variety of alternatives and opportunities to be poly.
