If a man is living his life as if he were actually a woman, just hasn't gone through the transition, is she not a woman? She introduces herself as a woman, she does the societal standards of feminine things (dressing like one, wearing make-up, longer hair, shaving body hair, etc.), and literally the only way to tell that she has a penis is to see her naked. I don't know about you, but a person who is living full time as the opposite sex is that sex in my eyes.
