Or just homosexual liars? A new study claims that self-identified bisexual men are "usually homosexual, but are ambivalent about their homosexuality or simply closeted. 'You're either gay, straight or lying,' as some gay men have put it."
Women, on the other hand, are less picky by nature, according to Dr. Lisa Diamond: You may be mostly interested in women but, hey, the guy who delivers the pizza is really hot, and what are you going to do?"
I'm not sure whether to be insulted or flattered by that description as a woman, but I do know it's dangerous and somewhat presumptuous for science to tell human beings what their sexual orientation can or cannot be.
