As people pass from childhood into their teen years and beyond, their bodies develop and change. So do their emotions and feelings. It's common to wonder and sometimes worry about new sexual feelings.
W hy are scientists so preoccupied with what causes homosexuality, to the near-total exclusion of the factors that lead to heterosexuality? I don't object to research into sexual orientation. It is the one-sided obsession that bugs me.
The relationship between the environment and sexual orientation is a subject of research. In the study of sexual orientationsome researchers distinguish environmental influences from hormonal influences,  while other researchers include biological influences such as prenatal hormones as part of environmental influences. Scientists do not know the exact cause of sexual orientation, but they theorize that it is the result of a complex interplay of genetichormonaland environmental influences.
This report references studies from the s to present day. Pleaes note that some of the older information has been superceded by more recent studies, and is included here as an historical document. This summary sheet is not intended to be a comparative analysis or recommendation of the studies referenced. Studies often differ sharply in: 1 definitions; 2 methodology; 3 response rates.
Homosexuality is romantic attraction, sexual attractionor sexual behavior between members of the same sex or gender. It "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions. Along with bisexuality and heterosexualityhomosexuality is one of the three main categories of sexual orientation within the heterosexual—homosexual continuum.

In addition, about 60 per cent of the pre-adolescent boys engage in homosexual activities, and there is an additional group of adult males who avoid overt contacts but who are quite aware of their potentialities for reacting to other males. The social significance of the homosexual is considerably emphasized by the fact that both Jewish and Christian churches have considered this aspect of human sexuality to be abnormal and immoral. Social custom and our AngloAmerican law are sometimes very severe in penalizing one who is discovered to have had homosexual relations.
Relationships with overt adult Kinsey Scale scores K indicate that early sexual experiences are most closely related to K, followed in order by gender related and familial variables. A developmental model emphasizing social learning is presented. Interviewees were American white males and females. Elevated K more homosexual scores was found for females who had few girl companions at age 10 and few male companions at 16, had learned to masturbate by being masturbated by a female, had intense prepubertal sexual contact with boys or men, found thought or sight of females, but not males, arousing by age 18, had homosexual contact by age 18, higher K at 17, and higher first-year homosexual behavior frequency.
However, it is only relatively recently that developmental scientists have conducted controlled studies with one clear aim in mind, which is to go beyond mere stereotypes and accurately identity the most reliable signs of later homosexuality. In looking carefully at the childhoods of now-gay adults, researchers are finding an intriguing set of early behavioral indicators that homosexuals seem to have in common. And, curiously enough, the age-old homophobic fears of parents seem to have some genuine predictive currency.
