Katie,
I hope I didn't hijack your post with my comments. To your point about cis-crossdressers, I'd have to say that I don't think I'm "cis." As a part-time woman, I feel very strongly that my personality is comprised of two distinctive halves. There is the male half and the female half, and when I'm expressing my female side, I feel that I am really a woman. There is way much more going on inside of me than just a penchant for feminine attire. Ultimately, these personal feelings probably keep me from answering your original question accurately.
Hugs,
Sally
