For a couple of years there, when I first came "out", I was really into "IT" and felt like my feelings were becoming unbalanced in sort of a female way, so actually had to "gear down" a bit to feel comfortable. This is why I know just how powerful these feelings can be and the old saying that you want something so bad you can "taste" it applied.
There is no doubt in my mind I could have followed through and seen this transition process to conclusion, including possibly physical transition. What I eventually realized though is that I would never be satisfied with being JUST a woman. To truely be myself, I had to combine the feelings to be a whole and complete person and so what I was physically didn't really matter that much any more. So,in essence, I am a man, yes, but am also a "woman" in many ways and can perform both roles with equal ease. Sometimes you more or less have to "live it" to find out what your capabilities really are.
