我們在性健康問題概述中列舉了下列的性功能障礙：

1. 性偏惡
2. 性欲抑制
3. 性交疼痛
4. 陰道痙攣
5. 膨脹問題(缺乏勃起或勃起軟弱，缺乏潤滑或潤滑不足)
6. 性高潮問題(性高潮時機不滿足，無性高潮)

後三種是“傳統的”性功能障礙，它們是本講的主題內容。前三種是不同狀態下特殊的性健康問題。所以，我們在此首先討論前三種性功能障礙。

In our general overview of sexual health problems we have listed the following sexual dysfunctions:

1. Sexual aversion
2. Inhibited sexual desire
3. Pain during sexual activity
4. Vaginismus
5. Problems of tumescence (absent or weak erection, absent or weak lubrication)
6. Problems of orgasm (unsatisfactory timing of orgasm, no orgasm)

The last three of these are the "classic" dysfunctions which are the subject of this course. The first three are particular health problems of a different order. Therefore, they will here be discussed first and separately from the others.
