Hi StacyCat,
I understand where you are coming from. And no you're not a freak (or else I am too)
Ken and I are in a deep poly relationship with a woman (mostly a Vee).
On the other hand sometimes I want something a little different. Nothing wrong with that. Ken accepts it, so sometimes I just go play. We've got rules about proper precautions, but other than that I can play with anyone that Ken hasn't explicitly vetoed.
So, I don't think what you want is weird at all.
