I don't mean this as an attack on you. I'm just trying to get at why I feel the way I do.
If you're attracted to feminine men as well as women you are still bisexual though, unless you're not finding them sexually attractive - just noticing good looking feminine men more. With love and things coming in it gets all confusing and yes there are lots of variations on it.
I put sexuality down to sexual attraction though, which I would say is not fluid, just has a lot of different grays along the scale. I think people change what they identify as simply because we're used to such rigid terminology, rather than them actually changing themselves.
