3. 高潮期 一些基本的觀察結果 性高潮（Orgasm 自希臘語：orgasmos 貪欲的興奮）是肌肉和神經張力在性興奮頂峰的一種驟然釋放。性高潮體驗代表著最強烈的身體愉悅。人類有能力體驗這種身體愉悅，而且在男在女都基本相同。一次性高潮僅持續數分鐘，它是一種讓人感到非常像痙攣的身體反應或涉及全身的一系列抽搐，而且不久會導致全身放鬆。

3. Orgasm

Some general observations 
Orgasm (gr. orgasmos: lustful excitement) is the sudden release of muscular and nervous tension at the climax of sexual excitement. The experience represents the most intense physical pleasure of which human beings are capable and is basically the same for females and males. An orgasm lasts only a few moments and is felt very much like a seizure or rather a series of convulsions which involve the whole body and soon lead to complete relaxation.
