性的层阶问题 |
|
当然，诸如此类的分类不是什么创新的和革命性的进展。众所周知，存在参与异性性行为的人，也存在参与同性性行为的人。人们也熟知，一些人与两个性别都有性行为发生。不过，在金西的大型统计学调查研究之前，大多数“专家”只是假定专有异性性行为的人的百分比是如此之大，而其它所有类型的性行为的人的百分比是如此之小，以至于任何等级量表也绝无希望超出于这个分布范围。换一句话说，有人认为同性性举止（homosexual
act）是如此罕见，只不过代表着“不正常的”和反常的例外状态。
金西证实了这种传统的观点是完全错误的。例如，他的统计数据揭示，随着人到中年，约50%的男性（和20%的女性）与自己的性别成员就已经有了某种明显的性爱体验。这些统计数据后来引起了争议，而且其他研究者得到了低得多的百分比统计数据。然而，金西的基础研究成果经住了时间的考验：异性恋和同性恋是层阶问题： |
性取向
-
用性取向定义一个人的异性恋或同性恋状态。一个人的性取向以他/她的性伴的偏好为基础。
-
人们在性的层级上是异性恋或同性恋，这就表明他们被另一性的性伴所性吸引或被同性所性吸引。大多数个体发展成明显的对另一性的性伴有性喜好(异性恋)。
-
但是，少数人对男性和女性都有性吸引喜好)双性恋)，甚至还有更少的人主要对自身性别的性伴有性吸引喜好(同性恋)。

3. Homosexual Intercourse
|
|
A Matter of Degree
|
|
There is, of course, nothing new or revolutionary about these categories as such. It has always been known that there are people who engage only in heterosexual intercourse, and that there are others who engage only in homosexual intercourse. It was also well understood that some individuals have intercourse with members of both sexes. However, before Kinsey’s large statistical studies, most “experts” simply assumed that the percentage of people with exclusively heterosexual histories was so great and the percentage of all others so small that any scale would have been hopelessly out of balance. In other words, homosexual acts were believed to be so rare as to represent nothing more than "unnatural" and freakish exceptions.
Kinsey showed that this traditional view was quite mistaken. For example, his statistics revealed that, by the time they reach middle age, about 50% of all males (and 20% of all females) have had some sort of overt erotic experience with members of their own sex. These numbers were later disputed, and other researchers arrived at much lower percentages. Nevertheless, Kinsey’s basic finding has stood the test of time:
Heterosexuality and homosexuality are matters of degree:
|
|
|
Sexual Orientation
-
Sexual orientation is defined as a person's heterosexuality or homosexuality. It is determined on the basis of preference for sexual partners.
-
People are heterosexual or homosexual to the degree in which they are erotically attracted to partners of the other or same sex.
Most individuals develop a clear erotic preference for partners of the other sex (heterosexuality).
-
However, a minority are erotically attracted to both women and men (bisexuality), and an even smaller minority are attracted mainly to partners of their own sex (homosexuality).
