Ancient Greek writers such as Plato and Plutarch would have us believe that homosexual relations in Ancient Greece - often occurring in the context of a young man's education (paideia), between citizens and slaves, and often encouraged in military contexts such as in Ancient Sparta or the Sacred Band of Thebes - were common. I have little doubt that homosexual orientation among the Ancients would have been no more prevalent than it is today (that is, of course, if we agree that homosexuality is a product of biology), yet homosexual relations are portrayed as seemingly rampant. So I ask this, were the ancient Greeks testament to the fluidity of sexuality in such a way that they demonstrated that man is able to form relations with either sex to an extent much greater than it is commonly believed today? I don't wish to offend anybody, but do you think that the history of homosexuality in Ancient Greece puts to question the veracity of statements such as "I couldn't possibly have sex with him/her, because I'm straight/gay" or even the notion that straight men are only able to form close emotional bonds with women, and that gay men are only able to form close emotional bonds with men?
