性行為的發展

性行為的發展概述

在上一節裏，我們已經把人類的性行為區分為三個要素——性能力、性動機和性行動[1]。

我們也已經解釋過，這些要素並不是強度相等的固定實體，而是隨著時間的推移它們各自的消長和意義都會發生改變[2]。

的確如此，人類的性行為在其能力、動機和行動方面從生到死都會經歷一個持續的發展過程。這個發展過程有時是緩慢的和剛好能夠被察覺的（例如在孩童時期），在其它年齡時期，其發展是迅速的和引人注目的（例如在青春期）。可是，甚至在成人期和老年期，性行為的發展也持續地發生變化，一些變化是不十分明顯的和逐漸的，其它的變化是突然的和引人注目的。簡而言之，一個人的性能力、性動機和性行動在人生的不同時期會以不同的節奏發生著變化。

這些變化有兩個原因：

① 生物、自然的原因：機體生長與衰老的原因。

② 社會心理原因：性腳本（sexual script）的學習與忘卻的原因。

本章將詳細討論這種變化及其原因。

Development of Sexual Behavior

Introduction

In an earlier section, we had distinguished between 3 basic factors in human sexual behavior - capacity, motivation, and performance.

We had also explained that these factors are not fixed entities of equal force, and that their balance and significance shift over time (see here).

Indeed, human sexual behavior, in its capacity, motivation, and performance, undergoes a continuing development from birth to death. This development is sometimes slow and barely noticeable (for example in childhood), at other times it is fast and dramatic (for example during puberty). However, even in adulthood and old age there continue to be changes, and some of these can also be subtle and gradual, others sudden and striking. In short, a person’s sexual capacity, motivation, and performance change at different paces in different phases of life.

These changes have two kinds of causes:

1. Biological, natural causes: The growth and decline of the body.
2. Psychosocial causes: The learning and unlearning of sexual scripts.

The following sections will discuss the changes and their causes in greater detail.
