I have thought about this as well. I am listed as bi (mrs) but it doesn't mean that I am bi with everyone. Just because I am, doesn't mean you have to be. If it happens, hey, bonus for me. But then again, if we start out as full swap, and the female 1/2 and I start enjoying each other, then the hubbies get left watching. I haven't heard him complain, so I guess thats a good thing.
I guess my point is, just because I list myself as bi, don't exclude us as prospective playmates.
