There are gay animals - Biological Exuberance is a great book on the subject - but I think your friend is a bit confused about the chemical imbalance thing.

The info that I'm familiar with is that homosexuals have a different chemical reaction in the hypothalamus than heterosexuals - that's not suggesting that there's an imbalance, but a structural difference between homosexual and heterosexual brains which cause them to react differently and produce different serotonin levels. That does not mean that serotonin levels CAUSE the homosexuality, but that they are a result of it.

Sexual Orientation Among Men Is Connected With Brain Metabolism, University Of Chicago Research Shows

Researchers at the University of Chicago have shown for the first time that strong sexual orientation among men appears to be connected with brain metabolism.

"We know from studies on rats that the hypothalamus is strongly connected with sexual activity. We also know from those studies that the neurotransmitter serotonin is associated with sexual behavior and arousal," Moltz said.

The research team theorized that hypothalamic differences may reflect biological differences between men with strong sexual orientation differences.
