Of course. For example, those who committed suicide on this basis, or who killed sexuality in general. In the overwhelming majority of cases, it is not possible to change the orientation - it was found out a long time ago. And some incidents with dubious interpretation may take place, but they do not prove anything.
The confusion in the question is brought about by the fact that many confuse orientation and behavior. A person can be made to behave in a wrong orientation ... And he can force himself. Orientation is preferred sexual behavior under conditions of absolutely free choice (or under equal conditions). Without the pressure of society, including its assimilated prejudices, external circumstances, fears and concerns. Actual sexual behavior can differ from preferred behavior for a variety of reasons. Starting from a scarcity of preferred partners and ending with religious dogmas and simply the fear of suffering.
Behavior can be changed. And the mistake of many psychotherapists, that they are trying to change orientation, is looking for ways to change orientation, and not ways of acceptable behavior change.
It is possible to "defeat" your homosexual behavior by strictly abstaining from sexual contacts. It is impossible to "defeat" homosexuality.
Sexual orientation is an innate, unchanging and normal feature of human organisms. It is formed in the prenatal period and is recognized in puberty.
Even if a person stops having sex or begins to forcefully have sex with people of the opposite sex, such a person will still feel homosexual (romantic or sexual - it doesn't matter), and he will not be pleased with sex with a person of the opposite sex .
As you have already been answered, doing something like that, whether on your own, or with the help of doctors, or some other traditional healers, is a very ungrateful and senseless business, and besides, it's really easier to just finally break your age-old foundations and accept the fact that with what is the norm - you do not need to fight, but on the contrary, you need to fight against the wrong point of view on this problem and widespread discrimination, both at the general social level and on the personal level. Concerning directly the topic of your question , you need to turn to history. It should be said here that thanks to the barbaric methods of doctors, it was possible that there were a very limited number of people who "defeated" their homosexual inclination, but often this also correlated with the fact that they had no sexual attraction at all.
From the end of the 19th century to the beginning of the 20th century, they tried to treat homosexuals with the help of castration. The healers of that time naively hoped that by removing the sex glands, they would forever relieve the patient of his attraction to men. Some "gays" went to the operation voluntarily, others were forced. However, the results of such treatment were disappointing, the sexual orientation of homosexual eunuchs did not change, and over time, sexual attraction faded away to anyone at all.
Then came the era of Pavlov, with his beautiful theory of conditioned reflexes, of course, the luminaries of medicine of that time could not bypass this scientific breakthrough, and began to use Pavlov's achievements in attempts to cure homosexuality. At first, the conditional "patient" was forced to masturbate in a dark room, but when he finally reached the culmination of this action, the light in the room was suddenly turned on, and the patient saw a naked woman or her photograph in front of him. It was assumed that after several such sessions, a homosexual would have a reflex to be excited by the sight of a woman's body, but hopes were not justified.
As they say, the carrot does not work - it means that you have to whip, the doctors decided to do the same. The homosexual was shown pictures of naked men and, as soon as he became aroused, was shocked or given a vomiting substance. Doctors made sure that the sight of a male body disgusted patients. The course of treatment was up to 20 or more sessions. Disgust arose, but it turned out to be temporary. In the 50s, another type of surgical treatment of "sick" appeared. But this time, the doctors decided to cut not the genitals, but the brain. Making a lobotomy, surgeons, guided by their own preferences, cut the bridge between the cerebral hemispheres, cut the hypothalamus, and destroyed the structures responsible for sexual behavior. The results of such operations were several: a complete loss of sexual desire, impaired coordination of movements, paralysis, vision problems and a bunch of other by-products of such destructive activity in relation to the brain. Since the 1970s, at the request of the medical community, such operations have been discontinued. Before the discovery of sex hormones, doctors began to use them in treatment. But, alas, here too they failed. Homosexuals who took female hormones in large quantities lost all sexual attraction, but at the same time they suddenly began to get fat, and many of them grew breasts. In those who took male hormones, sexual activity, on the contrary, increased, but they did not stop loving their own kind.
Various schools of psychotherapy were also used for treatment, including auto-training, hypnosis and a combination of all of the above methods with psychotherapy, but nothing gave a positive result, because this simply could not be expected, and now the scientific community understands this.
However, in the USA, against the background of this boom in the treatment of homosexuality, the ex -gays, which began its activity simultaneously with the recognition by the American Psychiatric Association in 1973 of the fact that homosexuality is not a disease and does not require treatment. The "former" gays fought for traditional values, called on the "gay" to go for treatment and in every possible way promoted their ideas and stories of "healing". They were supported, by the way, by a variety of religious organizations (well, who would doubt it) Christians, Catholics, Mormons, Jews and Muslims. But, over time, this movement lost its relevance, or rather, failed miserably. The scientific community has criticized their ideas that orientation can be changed, or, if they fail, celibacy should be observed for the rest of their days. Numerous studies by the American Psychiatric Association have shown that, to one degree or another, people who decided to confide in ex-gays and "heal" only increased the number of bouts of depression, neuroses, suicidal tendencies appeared, which were often embodied in life. Well, it all ended with the fact that the founders of the largest ex-gay organization Michael Bussé and Gary Cooper left it and began to live together as a same-sex couple. Then many other organizers followed their example, disbanded their organizations and apologized to the LGBT community, most of the participants who left the previous organizations became gay activists, on the contrary, ex-ex-gay movements were created that provided support to those who were in To one degree or another he suffered while trying to heal and accept a new self. Communities began to be created in which they tried to combine homosexual orientation and religion, allowing their activists to come to terms with the fact that they are gay and, at the same time, they could continue to pray to God and all that stuff.
So that, in my opinion, at this stage of development, we should not defeat homosexuality, but excessive prejudices and stereotypical, categorical thinking that has developed in the minds of most ordinary people, this, by the way, is very important for Russia and many other CIS countries, as well as for countries of the Middle (especially) and the Far East. But similarviews now, unfortunately, are not fading away at all, but, on the contrary, they are also strengthening, being a component of those very "spiritual bonds", they say - "Let's not let depraved Pindos and Europeans into our heterosexual Russia!" ... All this is the reason for the growth of intolerance, incitement of hostility on a sexual basis, which in turn leads to an even greater growth of the conflict, and in the end we come to very disastrous consequences, including suicides or murders, as in Chechnya, for example. (Ramzan Akhmatovich, I apologize in advance!).
There is a theory that sexual orientation is formed in the bud. It is simply realized already at a more conscious age.
In psychology, there is one classic case, a boy had an unsuccessful operation to circumcise the foreskin, it was necessary to remove the penis, after which the doctor suggested that his life would be full of complexes and ridicule and suggested that the parents change the sex of the child, allegedly it all depends on the environment and manner of education. Once a year, they were necessarily examined by the same doctor, underwent a series of tests, and the boy identified himself as a girl. The scientist earned himself popularity on this case, and began to continue operations of this type, inviting parents to independently choose the gender of the child they want to raise. But after a long period of time, after studying the fate of these children, it turned out that more than half of them were not attracted to the opposite sex, they admitted that from childhood they felt fascination with the individuals of their sex. Some of them decided to change their sex
