Bigender is basically separating a person's male and female sides. It's not a variation of multiple personality disorder, DID, or anything like that. It's just when a person feels more like "Jane" at times and "John" at others and prefer to separate them that way. It's solely a gender issue and not a psych issue. Does that help?
I think that we should keep in mind that others are just trying to understand and if someone doesn't understand, then we just need to explain it in another way until it's clear.

So let's try to not get too worked up.
I agree with Pica. I think all these terms we use are just variations of the same thing. We pick the term that we feel most comfortable with. But I can honestly say that I can relate with every androgyne term thrown around on here. Pre-gendered feels the best to me, so that's the one I use. But I have days where I feel bigendered, gender fluid, neutrosis, etc. But overall, I understand pre-gendered the best. Androgyne isn't a rigid state. There's room for interpretation and movement.
