性行为的发展

青春期的激素变化导致高灵敏度的性可唤起状态（sexual arousability），尤其在男青少年更甚。他们也许会有性高潮和在睡眠中射精（“梦遗”），并且他们也可能在清醒状态有未期而至和让人讨厌的勃起。甚至在首次射精之后的数年里，他们通常就会达到性能力的峰值状态。当无其它性释放途径时，他们可能会有频繁的自娱（手淫），在一些案例会有与一个或数个男性朋友相互自娱。通过这种途径，他们逐渐对自己的生理反应熟悉起来，他们此时清晰地识别为“性”反应。另一方面，许多少女当与“男友”有了亲昵行为的时候，第一次会有这种生理反应，即使在那时，这种性体验可能相当地弥散和无特异性。此外，在那个年纪，发生自娱的女孩数量只有男孩的一半。但是，总会有异议存在，总体上我们可以说：虽然女孩达到生理成熟要早于男孩，她们的“性”反应发展却比男孩要慢。因而，相同年龄的男女青少年通常会有性错配（sexual mismatch）。男孩会希望更多的身体接触，而女孩仍将勉为其难，这不仅因为社会习俗（影响）的原因[1]，而且还因为她未体验到同龄男孩的生理紧迫感。事实上，许多女孩只有在随后20多岁和30岁出头时，才会达到其最大的性动机和性能力的程度。

Stages of Development: Adolescence

Sexual Response 1

The hormonal changes of puberty produce an increased sexual arousability, especially in males. They may have orgasms and ejaculate in their sleep (“wet dreams”), and they may also have unexpected and unwelcome erections during their waking hours. Indeed, a few years after their first ejaculation, they usually reach the peak of their sexual capacity. When they have no other outlet, they may masturbate frequently, in some cases together with one or several male friends. This way, they become familiar with their own physical responses which they now clearly identify as “sexual”. On the other hand, many females first have these responses when they get involved with a “boy friend”, and even then the experience may be rather unfocussed and unspecific. Moreover, only half as many females as males masturbate at that age. There are always exceptions, but in general one can say: While girls achieve their physical maturity earlier than boys, their “sexual” response develops more slowly. Thus, female and male adolescents of the same age are, as a rule, sexually mismatched. The male will want greater physical intimacy, and the female will remain reluctant, not only because of social convention, but also because she does not share the male’s sense of urgency. In fact, many females will reach their greatest sexual motivation and capacity only in their late twenties and early thirties.
