I've heard of this concept (in some cases from gay friends of mine) called "hetro-gender". This refers to a crossdresser that takes on a sexual orientation according to the gender they are presenting. You might be bi.....or you might just be enjoying being accepted and treated as a woman. From my gay friends, I've often heard this with a certain amount of frustration. That is, they might be genuinely interested only to ultimately discover that the "hetero-gender" person is ultimately just playing a role. That is, they are not attracted to the person as much as they are the idea of being treated as a woman.
Obviously, I don't know your situation. You have to decide if being with a male is what "gets your motor running" or if it's really just being treated as a woman is what is doing it for you.
