The increase of homosexuality can at least reflect that people's values have changed: some people are not particularly ashamed of men or women. Some laws are promoting the legalization of homosexuality, not to mention the provisions that explicitly recognize homosexuality. It is precisely because of the discussion of this topic that it already contains the realistic possibility of homosexuality being recognized.
Homosexuality was rejected by public opinion in ancient society. Especially in the ancient feudal society of China, the distinction between men and women was very clear, and the idea that men were superior to women was very serious. At that time, Confucian etiquette thought didn't agree with homosexuality. Mainly because at that time, people's ideas were divided into male and female grades, and people were not completely equal.

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.
