Everyone is gay or straight, bi doesn't exist. There are no differences between the brains of straight and bi people, because they are the same thing - it shows in their behaviors.
Heterosexuality is boring to gay people because it's what everyone expects of them. Homosexuality is exciting to straight people because it is taboo. But since I can't say I'm straight when I have sex with men, I lie to society that I'm bi.
