Bisexuality, also known as bisexuality, is a sexual orientation and behavior that is not only a single gender (including males and females), but also a tendency for the body to be easily attracted. It is one of the three main trend categories, which is parallel to the trend of Heterosexuality and homosexuality. Individuals who are not sexually attractive to men and women are asexual. The National Sexual Health and Behavior Research in the United States shows that women are more bisexual than men, while women with same-sex tendencies are lower than men. Bisexuality refers to sexual orientation or human orientation, which mostly refers to the opposite sex or the generation of love for the same sex. Slow emotional or physiological satisfaction is called bisexuality. Bisexuality is not only about the admiration for a single gender, but also easily attracted to their bodies. Simply put, it means liking both the same sex and the opposite sex, and engaging in ambiguous or intimate behavior with the same sex.
Bisexuality has been recorded in various human societies, as well as in other animals.
From the perspective of etiology, bisexuality is different from ordinary people in terms of sexual psychology, sexual objects, and methods of satisfying sexual desires. Sexual activity does not target the opposite sex, or does not use sexual organ exchange between men and women to achieve sexual satisfaction.
1、 Bisexuality in Causology Biological Factors:
From the perspective of embryonic development, the early stages of fetal gonadal structure tend to form female organs. It is only because of the role of the Y chromosome that male gonads are caused. In the absence of fetal male hormone stimulation, the fetus will automatically develop into female features. To develop into a male, it is necessary to change the developmental pattern through hormones. If there are differences in the parts of the brain that receive male information through hormones during development, the female component will be retained in the male body. This not only explains why most men with sexual identity disorders and sexual orientation disorders are women, but also indicates whether they can develop into men or homosexuality from an early age. It can also explain why the levels of blood sex hormones in adult male transsexual patients and homosexuals are no different from those in normal males. That is to say, before birth, if some key parts of the brain are not Masculinization, they will not respond to the testosterone in the blood of children and adolescents in the future. The male hormone secretion of female transsexual patients is too much, which is also an animal experiment formed in the critical period before birth. It shows that the female born after receiving a large number of male hormones in the embryonic stage behaves similarly to the male, suggesting that sexual identity disorder may be caused. After birth, male hormones can only strengthen the performance of adult women, make the body Masculinization, and cannot change the identity and sexual direction of women.
