Psychological science bisexual

Bisexuality is romantic attraction, sexual attraction , or sexual behavior toward both males and females, [1] [2] [3] or to more than one sex or gender. The term bisexuality is mainly used in the context of human attraction to denote romantic or sexual feelings toward both men and women, [1] [2] [3] and the concept is one of the three main classifications of sexual orientation along with heterosexuality and homosexuality , all of which exist on the heterosexual—homosexual continuum. A bisexual identity does not necessarily equate to equal sexual attraction to both sexes; commonly, people who have a distinct but not exclusive sexual preference for one sex over the other also identify themselves as bisexual. Scientists do not know the exact cause of sexual orientation, but they theorize that it is caused by a complex interplay of genetic , hormonal , and environmental influences , [9] [10] [11] and do not view it as a choice. Bisexuality has been observed in various human societies [16] and elsewhere in the animal kingdom [17] [18] [19] throughout recorded history.

Bi men exist, new study says

Over the last 50 years, political rights for lesbian, gay, and bisexual LGB individuals have significantly broadened in some countries, while they have narrowed in others. In many parts of the world, political and popular support for LGB rights hinges on questions about the prevalence, causes, and consequences of non-heterosexual orientations. Michael Bailey of Northwestern University. The report is published in Psychological Science in the Public Interest , a journal of the Association for Psychological Science , and is accompanied by a commentary by psychological scientist Ritch Savin-Williams of Cornell University.
