This monograph presents a historical and theoretical review of homosexuality followed by a study of the self-perception of homosexuals. History bears out that homosexuality has always been one aspect of human sexuality and was more prominent in other periods of human history, depending on societal attitudes and mores. At present, many authors agree that "labeling theory" has a major impact on how the deviant behaves and how he views himself. The subjects in the present study consisted of 26 male and 27 female homosexuals; they were administered a questionnaire and a self-concept scale. The results show that, as hypothesized, the majority of respondents viewed themselves as being born homosexual; more women than men desired and had long-lasting love relationships in homosexual encounters; more men than women were less well adjusted in their deviance; and finally more women than men in the sample believed in sexual fidelity between gay lovers. The monograph ends with appendices that include the questionnaires used and the occupations of respondents by sex and age. (SE)
