Excuse me, I don't recall, but do you have a partner with whom you already swing? Is she bi?
From my perspective, the advice would be to set it up on your own. The way we (hubby, my boyfriend, and I) stumbled into adding two additional women to form our poly family was by me setting up hubby with my female friends and acquaintances. (Women like fucking other women's husbands, me giving permission only made it easier.) Many took up the offer (hubby is very attractive), few let me watch, and only several let me participate. That's what got me started on my path to Lesbianism and forming our family with Clair and Lora.
