I've always thought this sorta categorization was overly simplistic... unfairly assuming that woman's and men's sexuality works the same way.
I know I'm stereotyping, but men tend to be body-oriented and inflexible... and these scales seem to assume that women are as well. And while physicality is important to a point, IMHO a woman's sexuality is MUCH more complex and flexible. While it might be fair to tag a male "homosexual" if he's aroused by male bodies, there are situations where "heterosexual" women might find another woman erotic (a big difference here between "another woman" and "women in general"). But it's not the same thing, since *context* is a huge part of women's sexuality and can make up for a lack of physical attraction in some circumstances.
I'm still trying to figure myself out. I listen to gay men go on about men's bodies, and it's just not something I can relate to. That's not to say some men don't just stop me in my tracks when I see them, but it's more about their overall cuteness, a mischevious smile... whereas gay men seem to oogle other men physically exactly as heterosexual men oogle women's body parts.
On the other hand, I was watching Titanic for like the millioneth time last night (why I do this to myself,?), and that look of absolute adoration in Jack's eyes when he looks at Rose... god, I want that SO bad. I just go weak and melt inside. THAT'S what I want and need, and even though I can find women pretty, they can't give me that. They can't make me MELT.
Although to be fair, in 43 years my only sexual experience has been with one woman only... and we see how well THAT worked out... so what do I know?
A long post to basically say... I have NO idea where I'd fall on that scale, lol..
