But does this long standing phrase ring true in the hugely debated topic of penis size?

但真的如同這廣為「雞」論的諺語所說的嗎？

Does your member actually make a difference in attractiveness or ability to pleasure your partner?

那話兒的性能真的和取悅你的另一半，有關係嗎？

Interestingly, human have the largest penis of any primate, both in absolute size and relative to body proportion.

好玩的是，人類的陰莖是靈長類中最雄偉的，不論是實際或相對大小來說

So you can be proud of that! Through our evolutionary history, females likely developed an interest and preference for penis shape and size.

所以，你更應該要感到驕傲的！人類演化史上，女性對男性陰莖的外型大小產生偏好

Much like how female peacocks have a preference for male with stunning feathers.

如同母孔雀偏愛公孔雀身上驚豔的羽毛

As a result, they chose mates with larger penises, ultimately passing on those genes. This is known as sexual selection.

因此女性選擇有雄偉性器的男性，也將雄偉的基因傳下。這就是所知的「性選擇」

It also may have been an advantage for males, as a longer penis is more efficient at removing the sperm of rival males during intercourse.

或許這對雄性來說是個優勢，因為較長的性器，在性交時能有效地排除其他男性的精蟲

The longer your depth of thrust, the better semen displacement, ensuring your genes get passed on.

越深入體內，越能取代對手的精蟲，確保基因的流傳

One particular study found that some women experience more frequent vaginal orgasms with longer penises, suggetsting that it may be able to stimulate the entire length of the vagina and the cervix.

研究指出，較長的陰莖或許能刺激整個陰道與子宮頸，女性更能感到達到性高潮

However, it's important to note that women experience different types of orgasms.

不過，值得注意的是，每一位女性達到高潮的方式並非一樣

In fact, vaginal and clitoral orgasms may be completely seperate phenomena.

事實上，陰道與陰蒂的高潮可是不盡相同

They use different nerves, and even stimulate different areas of the brain.

因為兩者在神經的刺激與大腦區域不同

Even the coveted G-spot, another sexually sensitive area in women, is located only 1/3 of the way into the vagina.

甚至，女性的另一個敏感帶 G 點，僅僅佔陰道口的三分之一

Apart from this, many surveys of women have found that they're not nearly as concerned with size as men might think. And preference vary.

此外，根據女性們的調查，性器大小並非如男性所想那麼重要；因為各有所好

However, studies on homosexual men have shown they regard a larger penis as ideal.

相對地，對男同志來說，較大的陰莖反而較為理想

Another study in 2013 actually found that flaccid penis size may also be a major factor in male attractiveness, even before sexual contact.

2013 年的另一個研究指出，即使是性愛前，未充血的陰莖也會影響男性魅力

Which may seem odd considering we wear clothes nowadays, but for our ancestors, the genitals would have been visible.

說來奇怪因為現代人總穿著衣服，但人類祖先則是裸露性器官的

In the study women were asked to rank attractiveness of males based on computer generated images reflecting differet body types and penis sizes.

一項研究要求女性根據電腦圖像中，依不同的體態、性器大小的男性進行排名

From this, it was clear that not only were taller and more fit men much more desirable, but flaccid penis size played a role in their perceived attractiveness too.

結果顯示不僅身材高大、體格精實的男性較為炙手，未勃起的性器也佔一大因素

The larger the penis, the higher they were rated,

陰莖較大排名較高，不過有個限度

but there was a limit. A flaccid penis larger than about 7.6 cm and attractiveness began to diminish.

未充血的陰莖大於 7.6 公分，排名開始下滑

It would seem a penis in proportion may be most desirable. After all, over exaggerated traits, eve those related to attractiveness, can often be a sign of problems.

符合比例的陰莖最討人喜歡。畢竟，即使外在表徵和魅力相關，過大都不是個好現象

And it turns out that the person attached to the penis makes a difference too.

然而，同一個陰莖，不同的人，也會有不同的結果

With most all studies showing confidence, enjoyable personality, and attraction being the best predictor of sexual satisfaction.

多項研究指出，自信、好相處、有獨到吸引力，才是最佳的性愉悅要素

Ultimately, while size does seem to matter in some ways, bigger isn't always better!

最後，即使陰莖大小與否有一定關係，但是較大不一定是較好!
