I identify as bisexual and transgender. Fortunately the degree of dysphoria that I have is not enough to warrant transitioning. As I said recently in another thread, I do not believe that I have a male and a female persona. Depending upon how I choose to present, some thoughts and characteristics may bubble to the surface and others recede a bit. I went through very little of the common shame and guilt that many others talk about. I've never purged or even thought about it. The first time I dressed I was somewhat nervous about being seen by someone I know, but once I got over that, I could see that I had tapped into something that seemed very comfortable and that there was no need to resist as it didn't feel like foreign territory.
Eventually what I realized is that this feminine part has always been with me. Now that I have claimed this missing part of my identify, it does seem to be stable. So, as far as I can tell, I don't anticipate any significant changes.
For me, androgyny doesn't have much meaning. It would only represent external trappings and doesn't connect with me on a personal basis. I don't identify as androgynous, so why should I dress in that mode? On the other hand, do wear pink and variations and I wear fleece socks, many of which are described as women's by color and pattern.
I do not identify as gender fluid. You mention bipolar, but I don't think that is a good analogy. Bipolar seems to suggest two specific conditions; either/or. Fluid suggests change, so that would indicate a number of possible variations and not just two. In other words, there's male and female and many points between the two.
