Also for further academic discussion, there is one part of the brain, called the anterior commissure, that's bigger in gay men's brains than in those of heterosexual males. So, what's it do? It connects two structures together. The temporal lobes on each side of the brain, including the amygdala. So, what does the amygdala do? It's a very, very emotional structure. And it's fast. If you suddenly notice a bus heading toward you, and you feel a 'burst' of fear, that's your amygdala; the one on the right. If you feel a burst of elation when someone looks at you with attraction in their eyes, that's your amygdala, too; the one on the left.
