Great question with a lot of different answers. Just shows that although we have a common trait we are all over the spectrum.
As for myself, I am not unhappy being a male and at this point in my life I would not see the need to transition. If I had the same information and resources 40 yrs ago than what is available now, maybe I might have considered a different course. I do feel the need to express my "female" side on a regular basis and do wish I could do it more often than once a week or at least incorporate it more into my everyday presentation.
On the other hand, if I was to wake up one morning and was a woman and accepted as such by all that I met. I don't think I would have a problem adjusting to that also. Maybe when I retire and not have to worry about a job and earning an income maybe I will also reconsider my options. I'd like to be able to live in two places, one where I could me, and the other where I could be my female persona 24/7 for a long period of time and see how that would work for me.
