I completely understand where you're coming from, but I think this pigeonholes people too much. I understand the complications involved in dating when you have such a "secret" that you know you'll have to share, and even want the SO to enjoy rather than merely tolerate, which is a very exciting prospect.
Hanging around here you'll see a great variety of SO's that accept their partners for a great variety of reasons, and tolerate it or even love the CDing for many different reasons. So to limit your search to Bi's, while it does seem sensible on the surface, is perhaps limiting. So I think continue your search where you may, but don't limit it to that. It's often said that the right person comes where and when we least expect it, so keep an open mind.
