Patient V., 16 years old, studies in the 10th grade of high school. He consulted me in order to correct his homosexual desire on the initiative of his parents who, unlike him, regarded his sexual orientation as pathology. Under their strong psychological pressure he agreed on conversion therapy, since it, in his opinion, would not deteriorate him but would be better for his parents. On the moment of his visit the heterosexual component of sexual desire was entirely absent. His platonic (romantic) libido to girls was awakened at the age of 8-9, and the erotic one at the age of 10. His erotic desire to males was awakened at the age of 12-13, and the sexual desire a year later. At the age of 13 he arrived at the conclusion that he was a gay. When the patient was 14 he liked his classmate of the same age, whom he did not confess in it. They had companionship and “friendship”. He interacted with that boy during 1-1.5 years. At the age of 15 he had his first homosexual contact with a 36-year-old male. The patient had more than 20 sexual contacts with men aged 17-36. Any manifestations of gender incongruence had never been observed. His andrological status have no pathology. The provided correction was as follows: 1. Cognitive influences targeted at formation of the patient’s beliefs about advantages of the heterosexual lifestyle. 2. Hypnosuggestive correction. Programming was targeted at suggestion of futility of the homosexual lifestyle, removal of the homosexual desire and saturation with the heterosexual one, formation of associations between homosexuality and unpleasant sensations and landscapes, negative social consequences of homosexual relations, mental disorders and somatic problems observed in homosexuals. Hypnotic suggestions were also carried out aimed at changing the aesthetic and sexual perception of female and male persons, increasing sexual attraction to girls and women. A normal course of heterosexual masturbation was programmed. Besides, we performed modelling of the normal course of sexual intercourses with persons of the female sex in the hypnotic state. 3. Sexual-behavioural training (sex therapy) using masturbation of the heterosexual character with involvement of porn resources from Internet. Naturally, any use of homosexual plots during masturbation was strictly prohibited. 4. Also the patient was charged with a task to form an ideal of female beauty by focusing his attention on persons of the female sex both in the real life and in Internet. Twenty-one sessions of hypnosuggestive corrections were conducted. In the process of the provided therapy the homosexual component of libido was decreasing, while the heterosexual one was increasing. After the 18th session of hypnosis the heterosexual desire was expressed by 100% and the homosexual one by 0%. Then 3 more sessions of hypnosis were conducted in order to secure the achieved results. An inquiry of the patient 4 months later after the performed correction demonstrated their stability.
