Humiliation. No way. I don't mind humiliating single cell bigoted transphobs when I get the oportunity, but that isn't even that much fun anymore. Its kind of like fishing in an aquarium. Sure you will get something but there isn't that much sport in it.
Shocking the public. Not really. I enjoy being a woman and being accepted as a woman.
I will admit I am an adrenaline junkie. I do enjoy the rush when I enter a new social situation en femme. The first time shopping, flying, going out to eat or almost any activity en femme is comparable to skydiving. Deep down you know its going to be all right, but all that you can think about before you go out the door is all of the bad things that may happen. Once it is over you think wow that was fun and really all too easy.
