I know as well as had it confirmed by others my personality has changed since my sort of transition. I think a lot of it comes from me stopping myself from thinking and acting within very narrow and rigidly define lines of behavior that I said was "Guy". I was shy, introverted, the only emotion allowed was basically anger. The not talking was partly due to being a stutterer, the remainder being me. Except when it was allowed, when I needed to be in "Salesmen Mode" as I called it. I know now I wasn't channeling my inner salesmen, I was simply letting Joanne out.
