Sorry, I shouldn't have used that sort of description. What I meant was that as soon as someone finds both sexes sexually attractive, even if it's rarely for a particular sex, then that can be considered a spectrum, which is expected from bisexuality. To say the same for homosexuals and heterosexuals is to say that everyone is a little bi, which is incorrect.

As for spectrum, I mean it in the sense of any place between two extremes, the extremes being homo and hetero attraction, much like the Kinsey Scale. If someone is only interested in, say, men, you can't say that their sexuality is a spectrum. At no point are they going to find women sexually attractive, and if they do, then there's no shame in saying that they're bisexual and that their interests lean more towards men than women. That's perfectly fine.

But as a lesbian, I'm never going to find men sexually attractive. I may find some women more attractive than others, but I'm no more or less homosexual as a result.

Ignore the label part, you've made your point. I mostly saw it as a way for a person to weed out a majority of what they're not looking for. For example, if I use a lesbian label on a dating site, that should announce to any men who find me suitable that I am not interested in them. I understand that words have been muddied in recent times, so gay, lesbian, bisexual can mean fuck all these days, so idk. I guess I'm remembering a time when labels genuinely meant something concrete.
