BL and GAY seem to have a male-male relationship, but they are completely different in essence. I think BL is purer and nobler than GAY. It can be said that BL is a very avant-garde emotion. The following are their differences: BL: It is a love between beautiful teenagers that first appeared in Japanese comics. It is a literary work that attracts female readers. Although it involves love, it is rarely descriptive, and it is a very pure emotion. It can be understood that a boy falls in love with someone, but it's a pity that that person is also a boy. There is more spiritual love between them. They can have a physical relationship because of spiritual love, but they will never have love because they need physical pleasure. Mainly spiritual love, just like general love, except that the woman becomes a man. GAY: Unlike BL, they are people who like male characteristics or male bodies and want to have sex with men. To be exact, they have feelings to meet the needs of the body, not the people who like each other, but the body. It can be summarized as: BL: Spiritual love (through sublimation) can accept physical contact that is unacceptable (or they think there is no physical need). It's important to like each other. Homosexuality: I like male characteristics and figure, and I have feelings because of my physiological needs. It is important to like each other's looks or figure, but now some people are actually BL, but society thinks they are gay, and some people even think they are gay, because society can't distinguish BL from homosexuality well.
