性偏惡、性欲抑制和性交疼痛是特殊的性健康問題，它們有著多種多樣的病因，並且可能需要同樣多的生理和精神治療方法來應對。在一定程度上看，這三種性健康問題也可以歸類為“傳統的”性功能障礙；但是，大體上看，它們的病因比起後三種性功能障礙要清晰得多。此外，當代性治療已經為我們提供了大量的成功處理這些問題的定型的治療方案。由於本教程的局限性，我們因而只能集中討論這三種“傳統的”性功能障礙，並且只能對後三種性功能障礙作簡要概述。

Sexual aversion, inhibited sexual desire, and pain during sexual intercourse are particular health problems that can have a great variety of causes and may require an equally great variety of physical and psychological therapeutic approaches. To a certain extent, this is also true of the “classic” sexual dysfunctions, but on the whole, they present a much clearer picture. Moreover, modern sex therapy has provided us with a number of successful standardized treatments to deal with them. For the purpose of this course we therefore concentrate on the “classic” dysfunctions and cast only a cursury glance at the other problems.
