Every one here knows that I'm bisexual... Yet, oddly, I hit the same issues you do, Ashley Smith.
Usually, when I get even the slightest suspicion that a person is confusing gender identity with sexuality, I get right up in their face and very bluntly explain the difference. And strangely, it has worked thus far, but I'm working on trying not to be so up in their faces and blunt, just in case.
