性行為的基本類型

對自我性刺激認識的簡史

在世界不同的地方和在不同的歷史時期，對待自我性刺激的態度就已經存在差別。在一些時期，自我性刺激被推薦為一種健康措施，在另外的時期，卻被責難為對健康的嚴重威脅。一些宗教稱它嚴重違背習俗，而另一些宗教根本不予理睬。即使當我們只考慮西方的歷史，隨著時間的流逝，我們發現各種評價差異相當大，並且普遍流行的道德上有罪的評價發生了翻天覆地的改變，甚或完全顛倒了過來。

1. Sexual Self-stimulation

History

The attitudes toward sexual self-stimulation have been very different in different parts of the world and in different historical periods. At certain times it was recommended as a health measure, at other times condemned as a serious threat to health. Some religious authorities called it a grave sin, others paid no attention to it at all.  Even when we consider only the history of Western civilization, we find that, over time, opinions varied widely, and that general moral convictions changed dramatically or even completely reversed themselves.
