What Is a Penis For?

阴茎的功能是什么？

A penis has several functions:

阴茎有多种功能：

• Urination
• Sexual stimulation
• Penetrative sex
• Ejaculation

• 排尿
• 性刺激
• 插入式性行为
• 射精

For all of these functions, size is not the most important factor.

对于这些功能来说，尺寸并不是最重要的因素

Pleasure depends far more on arousal, communication, emotional safety, and technique.

愉悦更多取决于性唤起、沟通、安全感和互动方式

When Might Size Matter?

什么时候尺寸可能会影响？

Size may matter in practical situations such as:

在某些实际情况下，尺寸可能会影响，例如：

• Finding condoms that fit properly
• Avoiding discomfort or injury during penetration

• 选择合适尺寸的安全套
• 避免插入时造成不适或损伤

If a penis is very large, extra care and lubrication are important to prevent tearing.

如果尺寸较大，需要更多润滑和耐心，以避免受伤

If it is smaller, it does not mean it cannot provide pleasure.

如果尺寸较小，也并不代表不能带来愉悦

What Is “Normal”?

多大算正常？

Average erect length worldwide is about 12–14 cm.
Flaccid average is about 6–10 cm.

全球平均勃起长度大约12–14厘米
未勃起时约6–10厘米

There is natural variation. Some people are smaller, some larger.

There is no single “correct” size.

没有所谓的“标准尺寸”

Also, many people exaggerate or measure incorrectly.

而且很多人会夸大或测量方式不准确

Does Size Affect Pleasure?

尺寸会影响性愉悦吗？

Not as much as people think.

没有大家想象得那么重要

Most vaginal nerve endings are located in the outer third of the vagina.

阴道大部分神经末梢集中在外三分之一处

Clitoral stimulation plays a much bigger role in orgasm for many women.

对于很多女性来说，阴蒂刺激更重要

Technique, rhythm, emotional connection, and communication matter far more than length.

技巧、节奏、情感连接和沟通，比长度更重要

Not at all.

并不是

Larger size can sometimes cause:

Every size comes with its own considerations.

每种尺寸都有各自的注意事项

Can It Keep Growing?

还会继续长吗？

Penile growth usually completes by around 17–18 years old, though puberty timing varies.

阴茎通常在17–18岁左右发育完成，但青春期时间因人而异

Temporary shrinkage can occur due to cold, stress, fatigue, or after orgasm.

寒冷、压力、疲劳或高潮后都可能暂时变小

That is completely normal.

这都是正常现象

Can You Make It Bigger?

There are medical and non-medical options, but:

确实有一些医学或非医学方式，但：

• Hormones are not appropriate without medical need
• Pumps and devices may offer temporary effects

• 手术风险较高

大多数增大方式收益有限，却有真实风险

As a sex therapist, I would focus on:

• Communicating about pleasure
• Exploring different forms of intimacy

• 提升自然性唤起
• 练习盆底肌

Pleasure comes from connection, communication, and understanding each other’s bodies.

愉悦来自连接、沟通和对彼此身体的理解

你的身体不是比赛

And intimacy is not a measurement contest.

亲密关系也不是尺寸比较
