TSF-015 A 20-year-old male office worker who woke up as a woman: an in-depth interview. He had been bisexual and dominant, but after a major change, he discovered a new side of himself. Itaba Ao

To investigate the mystery of the rare condition known as acquired feminization, which causes a man’s body to change into a woman’s, we interviewed a former man said to have developed the condition. Before the transformation, he was already bisexual and had experience with sex with men. However, he preferred the active role and specialized in penetration. Regardless of the other person’s gender, he had a tendency to pursue any available opening, but after losing his penis, he could no longer take that role and fell into despair. Then, as he was led along by the staff, he gradually became absorbed in intimate experiences in his new role.
