I expect I will marry my bf, but imagining we parted ways, I would definitely date another CDer, so it's something I would want to know for sure. But my feelings almost identically mirror Reine's. I would want there to be a balance, and if he was transitioning or had thoughts to, that would not be of romantic interest to me, as I too am attracted to men.
This happens to women, too. Having grown up and lived most of my life fairly poor, hand-me-downs along with thrift store and clearance purchases have often meant my clothes don't fit as well as I'd like. You can Superman pantyhose and tights by putting a pair of panties over them to help keep them in place. Using or adding clips to bras to make them racerback helps with slipping straps. Chapstick helps prevent blisters from ill-fitting shoes. Sometimes you just have to get creative!
