性的意義
對於許多男女來說，乳房具有特殊的性意義。但是，正如所有的性事物一樣，對乳房的性意義偏好變化很大。在某些社會裏，長長下墜和擺動的乳房被認為是上乘品；在有些社會裏，偏好則指向圓隆和堅挺的乳房了。在某些文化中，小巧的乳房被讚美成漂亮的，而某些文化中，豐饒的胸部卻受到追捧。甚至在一種文化和相同文化裏，女性漂亮的概念從一代人到另一代人可能發生改變，當然，也會從一個個體到另一個個體發生改變。

Sexual significance
For many men and women, the breasts have a special sexual significance. However, as in all sexual matters, preferences vary widely. In certain societies, long, pendular breasts are considered superior; in others, the taste runs to the round and firm. In some cultures, small breasts are praised as the most beautiful, while in others the ideal is an ample bosom. Even within one and the same culture, the concept of female beauty may change from one generation to the next, indeed from one individual to another.
