There is peer pressure, fitting in, fear of rejection, dying to be like all the other girls, fulfilling the dream to somehow be accepted as a woman, to be seen as a woman, to have a sense that, "I am a woman."
I would suppose that that fulfillment is more difficult in a naked male, or partly female body, so I'd expect a "she to he" to be drawn toward female clothing, until the full change is performed. The people that I know admit that they are stuck in the middle at that big castration step. They do hormones, implants, but....
They often identify with being transgender, not a woman, or a woman almost, which is who they are and still having to identify outwardly as one or the other, wanting to identify as a woman, feeling as a woman. Yes, it is confusing and messy in the trans. Too bad that it isn't "cut" and dry, but it is expensive and scary and takes time.
John P., would it have something to do with her being trans that she may get too much attention from the curious, or does she enjoy talking about the process and outcome? Would that vary by her mood?
