A traumatic incident in the childhood of a woman led her to construct the fantasy that her father, a surgeon, had had the option of making her a girl or a boy when she was born. She vividly retained this fantasy in consciousness for twenty-seven years—including a long analysis with a woman analyst—without revealing it to anyone. In a second analysis with a man, the fantasy was suddenly communicated as if it had been a reality. As her father had intensely wished to have a boy, and treated his daughters as if they were boys, she had to work through in analysis until she felt sufficiently trusting that the analyst-doctor-father would not scorn her tender, erotic, feminine feelings before she was able to divulge the fantasy and free herself of the disabilities it had imposed.
