I don't know that many people would be educated enough to be so precise in defining themselves, nor would they want to put that kind of effort into it. I think you will have a hard time finding such people.

I personally take a person's "self-identity" as a general guideline, not as something precise and exacting. For myself, I identify as "Bisexual", when in reality, I am more "Pansexual" as I am attracted to more than just two genders at any one time. I also identify as "Hypersexual", but in some states that would get me committed :)...
