A lesbian in Oslo was in a heterosexual marriage that didn't work, so she started taking tranquillizers and ended up at the health sanatorium for treatment and rehabilitation ... The moment she said in a family group that she believed she was a lesbian, the doctor told her she was not. He knew from "looking into her eyes," he said. She had the eyes of a woman who wanted sexual intercourse with her husband. So she was subjected to a so-called "couch therapy." She was put into a comfortably heated room, naked, on a bed, and for an hour her husband was to ... try to excite her sexually ... The idea was that the touching was always to end with sexual intercourse. She felt stronger and stronger aversion. She threw up and sometimes ran out of the room to avoid this "treatment." The more strongly she asserted that she was a lesbian, the more violent the forced heterosexual intercourse became. This treatment went on for about six months. She escaped from that hospital, but she was brought back. Again she escaped. She has not been there since. In the end she realized that she had been subjected to forcible rape for six months.
