Oh I love answering questions!! <Claps hands> Glee!!!
I personally misinterpretted myself as a cross-dresser as I was growing up because I didn't understand why I felt the urges to do so. I love metaphors, <check out my gender model sometime in the general forum section> so let me try one here. I like eating italian food for example, and every time I went to eat italian afterwards I would get sick. Since I didn't know better, I just thought I was eatting too fast and having trouble digesting. Well when my symptoms were later identified as being Lactose Intolerant, that made more sense. The sickness was coordinated with eatting lactose based cheeses and sauces.
So in a similar fashion, if no one tells you the term bi-gendered, you wouldn't likely come to the conclusion yourself unless you sat down and seriously tried to put the pieces together. So when I felt the urge to crossdress, I thought ok I've seen and heard of people crossdressing, thats what I must be. The answer doesn't fit perfectly because the urges were quite inconsistant and to verying degrees. Later on when my identity was put into question because of new information, I started to research other possibilities. Could I want to be a girl deep down, is that what I really would be happy with. So I (am getting off topic, I'll steer back in a second) took the opportunity to assess myself and came to the conclusion I was absolutely bi-gendered, coming to the conclusion on my own without having actually found the bi-gendered term. When I found it and it matched, I was like "oh thats....me....cool I'm bigendered!")
<rambling and back!>
So I came to the conclusion that I was crossdressing not because I genuinely felt thats what I was, it was instead that the side that I wasn't acknowledging was overcompensating for this lack of attention by attempting to provide undeniable evidence I was different hoping I would one day question who I was deeper down. After I recognized her, at worse so far I've dressed androgynous but haven't crossdressed anymore. Did I get get bored with it? No, there was no reason for me to put that obvious hint out there any more since I knew why I did it before at last.
Does this apply to everybody though. No, not even close. Crossdressing in all its forms is extremely fun. I won't stop coming up with awesome halloween costumes that challenge the norm but I don't feel the reason I did it in normal situations applies anymore. It still is lots of fun and I imagine that crossdressers the world over love doing it.
Let me sum up my post of nothing relevant. The difference between a natural crossdresser, once again, doing it just for the fun of it, and a Bi-gendered androgyne that does crossdressing is that the bi-gendered androgyne....you know after all that, their reasons could be the same.
<sigh> I thought I had something to add.
Well I guess bi-gendered people differ from Crossdressers in one way I can identify concerning the topic of crossdressing(Mind you bi-gendered people are quite complex, but your questions imply talking about just the crossdressing issue). Bi-gendered people may not want to or need to crossdress at all, while due to the nature of their title, a crossdresser crossdresses. (Wow that was deep) <sigh>
Ending it now before I yap any longer. You're thinking, what was that mess, did they hit their keyboard with their head over and over again until the post was completed. Yeah, I did. I like ponies!
PS. The I like ponies phrase is an inside joke you're all now part of. I use that phrase whenever I want to stop rambling. I ramble like nothing you've ever seen. I've done this at job interviews when I answered a question with too much detail(stress related perhaps) or when I get too excited(like answering a question on here)(I mean I clapped my hands together and said in a high pitched squeal "Glee!", I'd say that shows enthusiasm.) I like ponies!
