Homosexuality is defined in Webster's Third New International Dictionary as "(1) atypical sexuality characterized by manifestation of sexual desire toward a member of one's own sex. ( 2) erotic activity with a member of one's own sex—compare Lesbianism. (3a) a stage in normal psychosexual development occurring during prepuberty in the male and during adolescence in the female during which libidinal gratification is sought with members of one's own sex. (3b) the extent to which one's libido is fixated at a homoerotic level." It is interesting that even in this nonmedical dictionary, homosexuality is viewed in three separate and different frames of references. In the first definition, misdirected sexual desire is the controlling element. In the second, erotic activity with a member of one's own sex is central to the interpretation. In the third, homosexuality is described as a stage of psychosexual development. As we are about to consider some interrelationships between hormones and homosexuality, the definition of homosexuality we employ becomes a matter of prime importance.
