As you can imagine all of these little character driven stories revolve around
the simple issues of sex, booze, relationships, having a good time and battling against the establishment.
A number
of scientific results suggest a biological basis for sexual orientation, but these results do not point to one
simple biological or genetic explanation.2 Perhaps the best recent reviews
of the scientific research relevant to this
issue are found in a special
issue of the journal Frontiers
of Neuroendocrinology, the official journal
of the International Neuroendocrine Federation and the American Neuroendocrine Society, that was published in April 2011.3 The papers in the special
issue make clear that substantial evidence exists in animals for biological bases
of sexual partner preference based on
sex.
