The propensity to behave sexually--unlike the frequency of sexual behavior--is not a discrete quantifiable phenomenon. At every stage of adulthood, sexual desire is produced by the interaction of biologic drive, psychologic motivation and cognitive aspiration. Motivation, the most clinically vital of these components, can be understood within four contexts: sexual identity, quality of the current non-sexual relationship, reasons for specific episodes of sexual behavior and transference from past significant attachments. The common psychological inhibitions of sexual desire can be translated into motivations for not behaving sexually deriving from one or more of these contexts. The less frequent excesses of desire can also be understood from the vantage points of these contexts. Rather than continue to oversimplify the concept of sexual desire, the term should be recognized as a shorthand means of referring to the mind's capacity to integrate biologic, intrapsychic and interpersonal complexity.
性行为倾向——与性行为频率不同——并非一种离散的可量化现象。在成年期的每个阶段，性欲都是由生物驱动力、心理动机和认知渴望相互作用产生的。动机是这些组成部分中临床上最为关键的，可从以下四个方面来理解：性身份、当前非性关系的质量、特定性行为发生的原因以及过往重要情感依恋的转移。性欲常见的心理抑制因素可转化为源于这些方面中一个或多个方面的无性行为动机。欲望较少出现的过度情况也可从这些方面的角度来理解。与其继续过度简化性欲的概念，不如将该术语视为一种简略表达方式，用于指代心智整合生物、心理内部和人际复杂性的能力。
