I agree with your test as an opening gambit. We have heard so many posters complain about the boys who hang outside of Toy Boys - they, almost invariably, pass your test. Moreover, they perform the way they agree to. However, just assigning "gay" or "straight" is saying there are only two points on a scale from 0 to 6. ( there is a 7 for asexuality )
Moreover, I urge you to consider the concencus of scientific opinion ( quite beyond Kinsey ) that this "self-belief" is genetic and not a learned behaviour. I believe that your multiplicity of interpretations is merely a loose way to discribe the operators which actualize the Kinsey findings.
Are you aware of the shame that many biologists express privately that they are afraid to release their actual findings that homosexual behavior is rampant in the entire animal kingdom? If sexuality is genetic, as the current consencus shows, then my analogy holds as a medical condition is as "solid" as the, not yet discovered, code for homosexual bahavior.
