“Partial Transition” can, and should, mean a broad range of things to different people. It is unnatural and futile to attempt imposing a definition as to what it should mean. We are transitioning to a truer expression of ourselves, and our selves may be different at different times/stages of our lives.
I, myself, am merely transitioning to androgyny. Or, rather, I find myself better expressing what I’ve been all along.
By not trying so hard to be male, and by not worrying myself with the impossibility of being female, I find greater ease in just being what I am - male with some “female” traits, that I no longer feel apologetic for.
I now understand and just am what is male about me, in a clearer way than I ever could before. And, if I just so happen to seem vaguely femme to my peers, I worry less and less about it.
The ironic thing is that my wife sees me as being more manly, as a result. She points out that most males are so infused with adolescent posturing, that it makes them seem foolish and insecure, by comparison.
