性行为的基本类型

直到最近，宗教和医学典据曾习惯于在“夜间玷污”或“夜间遗精(nocturnal emission)”的题项下讨论整个病症。直到20世纪中叶金西及其同事发表了一些可靠的统计数据为止，这一局面才得到改观。他们把“夜间遗精”认定为性释放的一种类型。统计数据显示，不仅男人，而且许多女人在睡眠中都有性高潮(尽管女性出现性高潮的比例较少)。 因而，金西不再谈及“夜间遗精”，而是说到“夜间性梦(nocturnal sex dream)”。这个术语可以用于两性，只不过仍不够精确。毕竟，性梦很可能会在午睡期间发生，对这种例子，我们必须称之为“日间性梦(diurnal sex dream，即在白天期间的性梦)”。因此，“睡眠期性高潮(orgasm during sleep)”似乎是可供运用的最简洁和最精确的术语了。

1. Sexual Self-stimulation: Orgasm During Sleep

Terms

Until fairly recently, religious and medical authorities were used to discussing the entire matter under the heading of "nocturnal pollution" or "nocturnal emission". It was not until around the middle of the 20th century that Kinsey and his associates presented some reliable statistics as to the frequency of this type of sexual outlet. The figures showed that not only males, but also many females, have orgasms in their sleep, although the percentage of females is smaller. As a consequence, Kinsey no longer spoke of "nocturnal emissions", but of "nocturnal sex dreams". This term could be applied to both sexes, but it is still not precise enough. After all, sexual dreams may very well occur during an afternoon nap, in which case they would have to be called "diurnal sex dreams" (i.e., sex dreams during the day). Therefore, it seems that "orgasm during sleep" is the simplest and most accurate term available.
