性行为的发展

这里有一个很好的例子，有两个男子的“性日记”详细地记载了他们青春期的性能力，我们称他们为Z先生和C先生。他们尽管住在欧洲不同的国家，却有很多共同特征：他们作为青少年，没有机会与人发生性行为，因而他们有自娱行为作为其性释放的唯一途径。一旦他们成年，他们都结了婚并有了孩子。两人也都保存了精确的日记，详列了他们超过50年的记录。这样的日记极为罕见，所以他们所记载的性活动内容不能视为具有代表性。尽管如此，仍用图表呈现如下，该图表覆盖了他们前20年的生活，他们的性行动档案清晰度也不能延续到成年期。至少在这一方面，日记仍然反映出一个典型的发展过程。他们的日记也证明了另外的普通男人在十多岁里也可能有高频率的性反应：在15-17岁之间，他们大约每年有900次的性高潮，即每天有2-3次。（实际上，Z先生的性活动在儿童期就已经开始；这个时期恰好在弗洛伊德假定的“潜伏期”）。

Stages of Development: Adolescence

Sexual Response 2

A good illustration of early male sexual capacity is provided by the sexual diaries of two men, Mr. Z and Mr. C. Although living in different European countries, they have sexually much in common: As adolescents, they had no opportunity for sexual intercourse and thus were left with masturbation as their only sexual outlet. Once they reached adulthood, they both married and had children. Both also kept precise diaries, listing their sexual activities over more than five decades. Such diaries are extremely rare, and their content can therefore not be considered representative. Still, the excerpts presented here, which cover the first twenty years of their lives, document levels of performance that neither could sustain in adulthood. In this respect at least, the diaries reflect a typical development. They also document that otherwise ordinary males can be sexually highly responsive in their teens: About 900 orgasms per year, i.e. 2 - 3 orgasms per day, between the ages of 15 and 17. (Actually, Mr. Z’s activity already begins in childhood during the “latency period” postulated by Freud.)
