古时候，性在婚姻中扮演着重要的角色，但与现代社会相比，古人对性的态度更为保守和封闭。在古代中国，性是不被广泛讨论的话题，很少在文学作品或历史记录中提及。然而，古人对于性前戏的认识和实践是存在的，虽然不被公开谈论，但是有着一套独特的“戏道”。

古时候性前戏被称为“戏道”，这是一种旨在增加夫妻之间情感和亲密度的行为。在古代的婚姻中，性被视为夫妻之间的一种纽带，是促进感情和亲密关系的重要因素。因此，古人认为性前戏是非常重要的，它可以增加夫妻之间的情感联系，并提高性生活的质量。

古代的戏道主要包括四个方面：言语、行为、情感和心理。言语方面，夫妻之间可以通过互相表达爱意和温柔的话语来增加情感的交流。行为方面，夫妻可以通过轻柔的触摸、亲吻和拥抱等行为来增加身体接触，从而引发性欲的激发。情感方面，夫妻之间可以通过互相倾诉、分享内心感受和理解对方的需求来增加情感的亲密度。心理方面，夫妻可以通过相互鼓励、支持和理解来建立起一种安全和信任的关系，从而为性生活创造一个良好的环境。
古代的戏道注重的是夫妻之间的情感和亲密度，而不仅仅是性行为本身。古人认为，性是一种身心合一的体验，只有在情感上达到一定的高度，才能够获得满足和快乐，尽管古代的戏道不同于现代社会的开放和自由，但它反映了古人对于性和婚姻的重视和尊重。


----------Introduction in English----------
In ancient times, sex played an important role in marriage, but compared to modern society, ancient people had a more conservative and closed attitude towards sex. In ancient China, sex was not a widely discussed topic and was rarely mentioned in literary works or historical records. However, the ancient people's understanding and practice of sexual foreplay existed, although it was not openly discussed, but it had a unique set of "theatrical techniques".
In ancient times, sexual foreplay was known as "drama", which was a behavior aimed at increasing emotions and intimacy between couples. In ancient marriage, sex was seen as a bond between spouses and an important factor in promoting emotional and intimate relationships. Therefore, the ancients believed that sexual foreplay was very important as it could increase the emotional connection between couples and improve the quality of sexual life.
The ancient drama mainly includes four aspects: speech, behavior, emotions, and psychology. In terms of language, couples can increase emotional communication by expressing love and gentle words to each other. In terms of behavior, couples can increase physical contact through gentle touching, kissing, and hugging, thereby triggering sexual arousal. In terms of emotions, couples can increase emotional intimacy by confiding in each other, sharing their inner feelings, and understanding each other's needs. Psychologically, couples can establish a safe and trusting relationship through mutual encouragement, support, and understanding, thereby creating a favorable environment for sexual activity.
The ancient drama emphasizes the emotions and intimacy between couples, rather than just the sexual behavior itself. The ancients believed that sex was an experience of physical and mental integration, and only when one reached a certain level of emotional satisfaction and happiness could one obtain it. Although ancient drama was different from the openness and freedom of modern society, it reflected the ancient people's emphasis and respect for sex and marriage.
