I’m now divorced because i was finally able to answer this question years ago. Crossdressing is what we do because of who we are, not “what” we are. We are a “who”, not a “what”. Our journey is each our own. We journey forward and we evolve. Some of us stop at different points and stay, some of use stay there, the rest eventually move forward.
At each stopping point, I used each one of those answers. Years went by, decades actually, and I finally came to the answer: I am a “who” and I cannot change who I am…. My character, my soul, my DNA, the fabric of self. I can change my behavior but the catalyst that dictates that change remains. We crossdress because of who we are, not what we are. In my case, I crossdress because I am transgender.
