Sexuality is merely the personality trait that determines which gender someone is attracted to. Like being right or left-handed, the only biological difference that can be found is in the brain. One study examined the brains of different deceased males and scientists often found a portion of the brain that was more developed in homosexual brains than in heterosexual. However, not all homosexual brains contained this difference, so while it correlates to homosexuality, it is not necessary for it to exist. Neurologists are learning more and more about the brain but how it relates to specific personality traits largely remains a mystery.
