3. The left breast is usually larger 左胸通常较大

No two breasts are exactly the same size, and it is usually your left breast that is bigger than the right side. However, often the difference is so slight you'd never notice they are of different sizes. Nipples also come in varying sizes, not only that, they also point in different directions.

女性的两个乳房并不完全一样大，左边的乳房通常稍大一些。由于两个乳房个头差异很少，你永远也不会注意到。有趣的是，乳头的大小也存在差异，并且指向不同的方向。
