Kenneth Dover in Greek Homosexuality and Michel Foucault in The Uses of Pleasure agree that homosexuality in Ancient Greek culture occurred within strictly defined social parameters. It did not exclude heterosexual relationships, but it was expected to take place between an older, socially established man (the erastes) and the younger lover (the eromenos) and contained elements of a mentorship role. As the younger partner matured in age, the relationship would eventually cease and the eromenos would go on to find a young partner in turn. Interestingly, it was cause for dishonor for one of the parties to exceed the social boundaries of the relationship by remaining in such an attachment longer than normal or becoming excessively fond of their partner.
