The definition of homosexuality used is "sexual and/or strong affectional relationships between persons of the same sex". This definition is based on that of Alfred C. Kinsey in his groundbreaking survey of over 5,000 United States men, Sexual Behavior in the Human Male (1948), p. 617, where the author defined homosexuality as "sexual relations, either overt or psychic, between individuals of the same sex" (for further discussion see the entry "Homosexuality" in my Encyclopedia of Male Homosexual Poetry and its Reception History now on the open internet).
