Homoeroticism is sexual attraction between members of the same sex, either male–male or female–female. The concept differs from the concept of homosexuality: it refers specifically to the desire itself, which can be temporary, whereas "homosexuality" implies a more permanent state of identity or sexual orientation. It is a much older concept than the 19th-century idea of homosexuality, and is depicted or manifested throughout the history of the visual arts and literature. It can also be found in performative forms; from theatre to the theatricality of uniformed movements. According to Oxford English Dictionary, it's "pertaining to or characterized by a tendency for erotic emotions to be centered on a person of the same sex; or pertaining to a homo-erotic person."
