You're just silly.
I'd not assume: "she'll rub my belly and I'll forever be seen in the light of "mommy" and not "woman"."
As for "not currently in a poly relationship" -- I consider myself in a poly relationship, even though Kevin & I are a garden variety same-sex couple at the moment. We're both poly, anyhow. And that makes us a poly couple -- open at any time to having others involved in our lives. So I figure anyone in a relationship, including a couple relationship, is still in a poly relationship.
