Sexual orientation is a complex issue, and there is no difference between different sexual orientations. There are many theories about the emergence of sexual orientation. At present, most scientists, psychologists and medical experts believe that sexual orientation is innate. A scientific document published by the American Psychological Association (APA) shows that long-term experimental records prove that homosexuality cannot be "corrected" and sexual orientation cannot be changed.
These situations are normal. Homosexuals will realize their sexual orientation sooner or later, which is closely related to their personal experience and social and cultural environment. This is because heterosexuals occupy an overwhelming advantage in number, and it is difficult for homosexuals to recognize their sexual orientation from an early age in an environment full of heterosexuals.
