For me my behavior and personality stay the same, I can be annoying no matter how I'm dressed, but this is probably because I have dressed since a very young age and my emotional sensitivity was not killed by the world so I have never been cut off from my feelings and have kept the capacity to cry in joy or sorrow and in every way be utterly natural in my emotional responses even at the risk of appearing weak or immature
What does change is how I act in public. Presenting myself as a male I do not worry about being assaulted by other men but dressed as a woman I become hyper alert out of fear a male may mistake me for a woman and make sexual advances only to than discover that I am not and become enraged. My fear of violence is what changes me based on how I'm presenting but I stay the same emotionally.
