Currently, I am blessed with fantastic metamours -- really, I couldn't ask for a more wonderful poly family. I tend to feel about my metamours the way I feel about siblings -- instead of sharing a parent, we share a lover. Like siblings, we know we need not do EVERYTHING together, but we do have to share and we do have a family bond.
Along with Poly Valentine's Week (so we have enough days to spend one with each of our lovers) I think we need a Metamour Day! Yay, Metamours!
