Homosexuality, also known as same-sex love, is a kind of sexual orientation, which refers to people who have only love and sexual desire for the same sex. Individuals with this sexual orientation are called homosexuals. Homosexuality is also common in other animals except human beings, but it is not the same as human homosexuality based on advanced emotions, which is also a concrete manifestation of the diversified development of human beings.
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.
Many researchers have come to a more consistent view: homosexuality has a profound biomedical foundation, and the sexual orientation of homosexuals is determined by gay gene and cannot be changed after the day. It's not a choice, and it's not something you can control.
Some homosexuals were clearly aware of their sexual orientation when they were 12 years old, while others should continue to explore their sexual orientation and gradually determine it when they were 12 ~ 16 years old. Most homosexuals can clearly know their sexual orientation at the age of 20. But some homosexuals may suddenly realize their sexual orientation and believe it when they are 40 to 50 years old.
