By Andy Coghlan. Some physical attributes of the homosexual brain resemble those found in the opposite sex. Brain scans have provided the most compelling evidence yet that being gay or straight is a biologically fixed trait. The scans reveal that in gay people, key structures of the brain governing emotion, mood, anxiety and aggressiveness resemble those in straight people of the opposite sex. The differences are likely to have been forged in the womb or in early infancy, says Ivanka Savic, who conducted the study at the Karolinska Institute in Stockholm, Sweden. First they used MRI scans to find out the overall volume and shapes of brains in a group of 90 volunteers consisting of 25 heterosexuals and 20 homosexuals of each gender.

Simon LeVay and the Biology of Sexual Orientation | The Bilerico Project
You so obviously cannot be gay , was her implication, because this is good sex. If you happened to engage in activity that ran counter to your sexual identity, then you had two options: you were lying to yourself and everyone else, or you were just experimenting. The sexual categories were rigid. My sexual journey through college was anything but run-of-the-mill. I came out at a conservative Christian college in the US and was in a gay relationship for around two years with a basketball player who ended up marrying a woman. I even went so far as to fall in love with one. As a writer, this kind of complicated story is incredibly interesting to me — mostly because it shows that my own personal history resists the kind of easy classifications that have come to dominate discussions of sexuality.
LeVay Shares Thoughts On 'Gay Gene' Research
There is a common belief among liberals that people are born either gay or straight. Conservatives tend to believe that sexual orientation is actually sexual preference, which is chosen by the individual. This page represents a review of the scientific literature on the basis for homosexual orientation. Are people born gay or straight? Much of the current media sources assume the question is a solved scientific problem with all the evidence pointing toward a biological probably genetic basis for a homosexual orientation.
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] [8] 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 , [10] [11] [12] and do not view it as a choice.
