This result can also be related to the Kinsey Scale:
0 = exclusively heterosexual 1 = predominantly heterosexual, incidentally homosexual 2 = predominantly heterosexual, but more than incidentally homosexual 3 = equally heterosexual and homosexual 4 = predominantly homosexual, but more than incidentally heterosexual 5 = predominantly homosexual, incidentally heterosexual 6 = exclusively homosexual
The idea of this excercise is to understand exactly how dynamic a person's sexual orientation can be, as well as how fluid it can be over a person's lifespan. While a person's number of actual homo/heterosexual encounters may be easy to categorize, their actual orientation may be completely different. Simple labels like "homosexual", "heterosexual", and "bisexual" need not be the only three options available to us.
