Hey Gerry, that's a word for that. It's called "bi"

[LSPoorEeyorick]

"Gay, straight, bi" assumes that people aren't fluid to begin with. I think some people - not all, mind you, but some people - are fluid, and move up and down the Kinsey scale depending on mood or age or experience, or whatever their choice or instinct. And I agree, SM, that you are demonstrating the tendency in question, of labeling someone who may not specifically fit the label, and who would prefer not to be labeled.

It's hard to come up with an appropriate parallel here, because there aren't a tremendous amount of things that have the liquidity of some people's sexuality without veering towards personal choice versus biology. My vegetarianism is as fluid as some people's sexuality, but I'm choosing that.
