The aim of the study was to explore the experiences of homosexual men connected with the formation of their sexual orientation in adolescence. A comparative study of 27 young adult homosexual men and 28 heterosexual men of similar age used a categorised interview questionnaire consisting of two parts: the first with questions regarding sexual dreams, fantasies and erotic encounters; the second with questions on family and social circumstances. The study yielded an abundance of interesting data on the psychological circumstances of (...) homosexual men during the formation of sexual orientation and its awareness as well as differences and similarities in that area between homosexual and heterosexual men. For instance, it revealed experience patterns concerning the formation of sexual identity and personal attitudes toward one’s sexual orientation characteristic of homosexual persons. The study verified the main hypothesis that mental-internal experiences precede behavioural-external ones both in homosexual and heterosexual persons. (shrink)
