Bisexuality has its own phylogeny. In most known societies ,you can find bisexual cases to different degrees. And bisexuality in these cases were treated as gay people(attention: heterosexuality , gay ,bisexuality are modern words which can not be found in ancient dictionary). In ancient times,gay were defined by some given behavior.
For example, in ancient Greece,men who have their own family usually keep relationship with same-sex partner. Actually, most emperors of Rome,most shoguns of Japan, part of Chinese emperors including Arab world were bisexuality. Bisexuality existed in different country of different times. Alexander the Great is one of the most famous bisexual emperors,he has uncountable harems,at the same time, he is in relationship with his friend Hephaestion.
Sparta also encourage homosexuality among the soldiers,including the married. Because in Sparta, people think bisexuality can unite soldiers and make soldiers more brave to protect their family and the people they love.
Temporary isolation or long distance travel and lack of the opposite sex environment, will make the heterosexuality tend to produce homosexual behavior in the short time to release depression. For example, the army, the prison, the concentration camp, the ocean going ships, the school. Generally speaking, when you leave the environment, the homosexual tendency is to end. Therefore, this homosexuality can also be referred to as the situation of gay people, because some of the environmental factors induced by the "false" homosexuals, known as the more suitable for the bisexuality.
The formation of bisexuality is related to the emotional experience of the youth.Generally,the period from age twelve to eighteen is called puberty.

Cabaret(1972)
Although Cabaret has become a key gay text, its fanboys and fangirls tend to deify the performances of Liza Minnelli as singer Sally Bowles and Joel Grey as the sexually ambiguous master of ceremonies. Both are magnificent, and both won Oscars. But the best, albeit far less showy, acting comes from Michael York as the bisexual writer (based on Christopher Isherwood, who penned the memoir upon which the musical is based) who moves to Berlin to complete a doctorate, but falls in with Minnelli’s glamorous cabaret singer. The two have a complicated relationship – they have sex with each other, and later find out they have been having a relationship with the same man, a rich baron.
