What Really Counts as a Big Penis? You Might Be Bigger Than You Think!

What Is a “Kyokon”? Understanding Size, Standards, and the Average Penis Size in Japan

The term “kyokon” (巨根), meaning “huge penis” in Japanese, generally refers to a man whose penis size significantly exceeds the average. However, the specific definition varies between individuals and is often vague.

In particular, what is considered “big” can differ greatly depending on culture and country. That’s why there’s no universal measurement that defines a kyokon.

In Japan, the average erect penis size is said to be around 12 to 13 cm (approximately 4.7 to 5.1 inches).
To be considered kyokon, a size well above average—typically 15 cm (5.9 inches) or more—is used as a general guideline.

That said, perceptions of “big” are relative.
While 15 cm may be seen as large in Japan, Western countries tend to have slightly different standards. In some regions, what is considered “large” may start at 17–18 cm or more.

It’s also important to note that impressions of size aren’t just about length—girth and overall proportions play a big role. So being longer doesn’t automatically mean being better.

Why are large penises seen as attractive? For many, it’s about the visual impact and the sexual confidence it symbolizes. But there are also downsides and inconveniences that can come with a larger size.

In the end, rather than worrying about whether you qualify as kyokon, what truly matters is communication with your partner and mutual sexual satisfaction.
Penis size is just one factor among many—and certainly not the only one that defines a fulfilling sex life.

A Thorough Investigation into Global “Big Penis” Standards: What Length Qualifies as “Large”?

What qualifies as a “big penis”—or kyokon in Japanese—varies significantly from country to country, and perspectives on size differ based on regional and cultural contexts. As a result, the definition of “big” is highly diverse worldwide.

According to international data on average erect penis size, some African countries report averages exceeding 16 cm (6.3 inches), while many Asian countries average closer to 12 cm (4.7 inches). These regional disparities in average size play a major role in shaping the threshold for what is considered “large.”

In Western countries, penises over 15 cm (approximately 6 inches) are often considered large. In the American and European adult film industries, sizes of 18 cm (7 inches) or even 20 cm (8 inches) and above are often highlighted and promoted as exceptionally big.

Western culture, heavily influenced by pornography and media, tends to associate larger penis size with status, dominance, and sexual appeal.

In contrast, in parts of East Asia and Southeast Asia, a length of 13–14 cm (5.1–5.5 inches) may already be considered large. In Japan as well, a penis longer than 15 cm is commonly regarded as kyokon, significantly above the national average.

Given these cultural and geographic differences, the question “What size is considered big?” has no single universal answer. Standards depend on local norms and expectations.

Ultimately, it’s important to have confidence in your own body while also understanding that ideas of “big” vary greatly across the globe.

Are You Considered “Big”? How to Measure Penis Size Properly and Understand the Standards

Many men have probably asked themselves at some point, “Am I well-endowed?”
But without knowing the correct way to measure or the standards used, it’s hard to make an accurate assessment.

Here’s a detailed guide on how to properly measure your penis size and what the general criteria are for being considered “big” (also known as kyokon in Japan).

How to Measure Your Penis: Basic Rules

Measure When Erect
To get an accurate size, the penis must be fully erect. Because there is often a significant difference between flaccid and erect size, comparisons are usually based on the erect state.

How to Measure Length
Use a ruler or measuring tape and measure from the base of the penis (at the pubic bone) to the tip of the glans.
Push gently against the fat at the base until you reach the bone to ensure an accurate measurement.
If the penis curves, try to straighten it as much as possible and measure along the top.

How to Measure Girth (Circumference)
Length isn’t the only factor—girth is just as important.
Wrap a tape measure or string around the thickest part of the erect shaft and measure the circumference.
This number can also influence sexual satisfaction, so it’s helpful to know both measurements.

What Qualifies as a “Big” Penis?

The standard for what’s considered “big” varies by country and culture, but generally:

• Length: Over 15 cm (approx. 5.9 inches)
  In Japan, a penis over 15 cm when erect is often considered kyokon, as it significantly exceeds the national average (about 12–13 cm).

• Girth (Diameter): Over 4.5 cm (approx. 1.77 inches)
  If the penis is thicker than a 500-yen coin, it’s commonly viewed as “thick” or “large.”

Average Penis Size: Japan vs. Global

• Japanese average (erect): approx. 13 cm (5.1 inches)

• Global average (erect): approx. 14.4 cm (5.7 inches)

These averages help establish the general benchmarks for what counts as “big.”

Other Tips

• Always measure in a relaxed environment to avoid stress-related shrinkage.

• Penis size can vary slightly depending on the season, health, or weight, so it’s a good idea to take several measurements and calculate an average.

What Are the Benefits of Having a Large Penis? Why It Attracts and Builds Confidence

Having a large penis—often referred to as a kyokon in Japan—is often seen as advantageous for several reasons. Among these, the most frequently cited are increased confidence and greater sexual appeal. Here’s a deeper look at why many men desire it and what benefits are commonly associated with it.

1. Enhanced Sexual Appeal

A larger penis is often seen as a symbol of sexual prowess.
Thanks to its frequent portrayal in pornography and media, the idea that “bigger is better” has become a common perception.
Men with large penises are more likely to be seen as confident in bed, which can enhance their attractiveness to potential partners.

2. Boost in Confidence

Many men feel a strong sense of self-confidence when they possess a larger penis.
Penis size is sometimes viewed as a reflection of masculinity, and feeling “above average” can give a psychological advantage.
This confidence can positively affect not just sexual encounters but also broader aspects of life such as relationships and social dynamics.

3. Increased Partner Satisfaction

For partners who prefer larger sizes, a kyokon can be a strong point of satisfaction.
Greater physical stimulation during intercourse may lead to higher levels of pleasure.
Additionally, the visual impact of a large penis can be arousing for some, enhancing overall sexual excitement.

4. Social Status & Conversation Starter

A large penis can also serve as a point of status in casual conversation, especially among men.
In some social circles, it becomes a topic of bragging rights or humor, and may even be brought up in conversations between partners.
Its “noteworthy” nature can make it a topic of attention.

5. Variety in Sexual Positions and Play

A larger size can open up new possibilities in sexual positions and scenarios.
Certain positions may feel more intense or satisfying when size plays a role, giving the individual more options in how they express intimacy.

The Surprising Downsides of Having a Large Penis: What You Should Know

While having a large penis (kyokon) may seem like a major advantage, it can also come with its own set of challenges and drawbacks. Being above average in size may lead to unexpected complications or inconveniences—both in the bedroom and in daily life.

Here’s a closer look at some of the surprising disadvantages that come with being well-endowed:

1. Discomfort or Pain During Sex

A larger penis can sometimes cause discomfort or pain for the partner during intercourse.
If the partner’s anatomy isn’t well-suited to the size, it may result in excessive stimulation of the vagina or anus, making sex less enjoyable—or even painful.
Forcing penetration can also lead to injury, so careful attention and communication are essential.

2. Limitations in Sexual Positions

Not every position works well for someone with a large penis.
Certain positions may make full insertion difficult or cause discomfort due to deep penetration.
As a result, some positions may need to be avoided, reducing variety during sex.

3. Difficulty Finding the Right Condom

Finding condoms that fit properly can be a hassle.
Most standard condoms may feel too tight or may be more prone to breaking, so people with larger penises often need to seek out specialty sizes.
Without a proper fit, there can be increased risk of pregnancy or sexually transmitted infections (STIs).

4. Everyday Inconveniences

Having a large penis can also be inconvenient in daily life.
It may be hard to find comfortable underwear or pants that fit well.
During physical activities, discomfort or shifting may occur.
In some cases, tight clothing may make the bulge overly noticeable, which can lead to awkward situations.

5. Performance Pressure

There’s a common stereotype that “a big penis equals amazing sex.”
This expectation can put pressure on both the individual and their partner.
You may feel that you have to deliver perfect sexual experiences just because of your size, which can create anxiety and reduce the ability to enjoy intimacy naturally.
Focusing too much on size may even distract from the emotional and physical connection.

6. Health Risks

An extremely large penis can lead to friction-related injuries or over-stretching during sex.
This can cause pain, small tears, or irritation.
If such issues occur frequently, they may raise longer-term health concerns, especially in the tissues and blood vessels around the penis.

In short, while being well-endowed can be a source of confidence and appeal, it also requires mindfulness, communication, and sometimes practical adjustments to ensure both partners enjoy a safe and satisfying experience.

What Is the Ideal Penis Size According to Women? Honest Opinions vs. Reality

“What size do women actually prefer?”
This question is something many men are curious about. However, the reality often differs from what media and adult entertainment portray. Women’s preferences vary widely, and there is no single ideal size.

In this article, we reveal the truth behind what women consider ideal when it comes to penis size.

1. Ideal Size Varies Greatly from Person to Person

The first thing to understand is that every woman has her own preferences.
Some women may find large penises attractive, but not all women are looking for bigger size. In fact, many value quality of sex and emotional connection over physical dimensions.

Surveys have shown that women often prioritize communication skills and sexual compatibility more than size.

2. Survey Results: What Size Do Women Prefer?

According to various surveys, the most commonly preferred penis length among women is between 13 and 15 cm (about 5.1 to 5.9 inches).
This range aligns closely with the average erect size of Japanese men, suggesting that average size is often viewed as ideal.

When the penis is too large, many women report discomfort or even pain during intercourse.
As for girth, “moderate thickness” is often preferred. Overly thick penises can make penetration painful, and thus are not necessarily seen as desirable.

3. What Women Really Value: It’s Not Just About Size

Many women honestly say that penis size is not that important to them.
What truly matters in sexual satisfaction are things like foreplay, emotional connection, and clear communication.

• Foreplay is key: Regardless of size, women often value foreplay more than the act itself. Understanding your partner’s desires and showing care can enhance the experience far more than size ever could.

• Communication: Being responsive and attentive to your partner’s needs is often seen as more important than physical attributes. Flexibility and kindness go a long way in building intimacy.

4. The Reality of an Oversized Penis

The idea that “bigger is better” is largely a media-driven myth.
In real-life situations, an overly large penis can cause discomfort or even pain for many women.

Rather than focusing solely on size, it’s far more beneficial to improve the overall quality of the sexual experience and to build a strong connection with your partner.

Want to Get Bigger? Evaluating Popular Penis Enlargement Methods and Supplements

For men who want to increase their size, penis enlargement techniques and supplements can seem like attractive solutions. However, many are unsure whether these methods truly work.

In this article, we take a detailed look at the reality and effectiveness of various enlargement strategies.

1. Types of Penis Enlargement Methods

There are several popular techniques for enlarging the penis, each with its own pros, cons, and level of scientific support:

Jelqing (Manual Stretching Technique)

Jelqing involves massaging the penis using hand motions to increase blood flow, which is believed to help enlarge size over time.
While it’s been discussed for years and is easy to try at home, there’s little scientific evidence to support its long-term effectiveness.
If done improperly or excessively, it may cause damage, so caution is essential.

Penis Extenders (Stretching Devices)

These devices work by applying continuous tension to the penis, based on the idea that stretching cells over time promotes growth.
Some clinical studies suggest mild results, but these devices must be worn for hours daily and may cause discomfort or pain.

Penis Pumps

Vacuum pumps temporarily increase penis size by drawing blood into the shaft, making it appear larger.
While effective for short-term results (e.g., before sex), the effect does not last and they are not effective for permanent enlargement.

2. Do Supplements Work?

There are many supplements on the market that claim to enhance penis size, but their effectiveness is questionable.
Most contain ingredients that improve blood circulation or boost libido, but very few actually increase size.

Common Ingredients & Their Effects

• L-Arginine: May help improve blood flow.

• Tribulus Terrestris & Maca: Often marketed for libido enhancement.
  These may help with erection quality but do not directly increase size.

Points to Be Cautious About

Many penis enlargement supplements lack scientific backing, and some may include unclear or risky ingredients.
Always check sources and avoid excessive expectations. Look for transparency in formulation and third-party testing where possible.

3. Real Effects and Risks

As of now, there is no magical or permanent method to significantly enlarge the penis.
Some methods may offer short-term effects, but achieving noticeable results often requires a long-term commitment.

Additionally, certain methods carry risks—including injury or side effects—so careful consideration and professional consultation are advised.

4. Psychological Effects

Focusing too much on penis size can impact self-esteem.
However, it’s important to understand that size alone is not the key to sexual satisfaction.

Improving communication with your partner and focusing on overall quality in intimacy can lead to far more satisfying results than chasing size.

Want to Get Bigger for Real? A Surgical Approach to Penis Enlargement Explained

For men who have a strong desire to increase the size of their penis, surgery is often seen as the most reliable option.
Penile enlargement surgery is considered one of the few methods that can offer measurable results—but it also comes with potential risks and significant costs.

Below, we break down the surgical approaches to penis enlargement, along with their benefits and drawbacks.

1. Types of Penis Enlargement Surgery

There are two main surgical techniques, each with a different focus:

Lengthening Surgery (Suspensory Ligament Release)

This procedure involves cutting the suspensory ligament at the base of the penis.
Doing so allows the internal part of the penis (normally hidden inside the body) to extend outward, making the penis appear longer—typically by 2–3 cm (0.8–1.2 inches).
Note: This surgery usually does not increase the erect length, only the flaccid appearance.

Girth Enhancement (Fat Transfer or Hyaluronic Acid Injections)

Fat is taken from the patient’s body and injected into the penis to increase thickness.
In recent years, injectable fillers such as hyaluronic acid or collagen have also become popular.
These procedures enhance the overall volume and visual impact of the penis.

2. Benefits of Surgery

• Definite Results
  Unlike supplements or devices, surgery can offer clear and measurable changes in length or girth.
  For those wanting significant enhancement, surgery is often the most effective choice.

• Long-Lasting Effects
  With proper aftercare, surgical results can be long-lasting.
  Especially in the case of fat transfer or filler injections, the effects can persist with periodic maintenance.

3. Drawbacks and Risks

• Surgical Risks
  As with any medical procedure, there are risks involved—such as infection, scarring, or numbness.
  Some outcomes may lead to an unnatural appearance, so surgeon skill and experience are critical.

• High Cost
  These procedures are typically considered cosmetic and are not covered by insurance.
  Costs can range from several thousand to tens of thousands of USD depending on the clinic and method.
  Injections like hyaluronic acid may also require ongoing maintenance, adding to the expense.

• Post-Op Downtime and Care
  After surgery, patients need time to recover.
  Activities including sexual intercourse may be restricted for several weeks or even months.
  Neglecting post-op care can lead to complications or diminished results.

4. What to Consider Before Going Under the Knife

If you’re considering penis enlargement surgery:

• Choose a reputable and experienced surgeon or clinic.
  Do not base your decision on price alone—lower cost often means higher risk.

• Get thorough pre-surgery counseling.
  Understand the realistic outcomes, potential risks, and post-surgical care before making your decision.

  Sex Tips for Well-Endowed Men: Building a Positive and Pleasurable Experience with Your Partner

For men with a large penis, sex often requires extra care and attention. While size may be perceived as a desirable trait, it can also lead to discomfort or even pain for the partner if not handled with sensitivity.

Here are key points well-endowed men should keep in mind to maintain a healthy, respectful, and enjoyable sexual relationship.

1. Proper Preparation Before Penetration

The first priority is to prepare your partner properly before penetration. This means engaging in thorough foreplay.
Foreplay helps your partner relax and allows the vagina or anus to become adequately lubricated and receptive, minimizing discomfort during insertion.

Once the body is ready and relaxed, even a larger penis can be accommodated more smoothly.

Communication Tip: Check in regularly during foreplay and before penetration. If your partner experiences discomfort or tension, don’t rush—proceed slowly and gently.

2. Use of Lubrication

Lubricant is especially helpful for men with larger size, as friction can increase discomfort.
Using a lubricant reduces resistance and helps ensure smoother, more comfortable penetration.

This is particularly important during first-time encounters or when your partner is nervous or tense.

Choosing the Right Lubricant:

• Silicone-based lubricants last longer and are ideal for well-endowed men.

• Water-based lubricants are easy to clean but may require reapplication during longer sessions.

3. Mind the Speed and Depth of Insertion

With a larger size, deep or fast penetration can cause pain or pressure.
Start slowly and gradually increase rhythm as your partner adjusts.

Slow & Gentle Entry:
Begin with shallow, gentle strokes and only increase depth once your partner is fully comfortable. Be mindful that deep penetration can strain sensitive areas like the cervix or inner vaginal walls.

4. Choose the Right Sexual Positions

Not all positions are ideal for well-endowed men. Some can lead to overly deep penetration, which might be uncomfortable for the partner.

Choosing positions that allow for depth control is key to a positive experience.

Recommended Positions:

• Side-lying (spooning) and modified doggy-style with shallow entry are often more comfortable.

• Positions like missionary, where deeper thrusts are easier, may require extra caution and control.

5. Maintain Frequent Communication During Sex

Open and honest communication during sex is crucial.
Check in frequently to ensure your partner is feeling comfortable and not in pain.

If discomfort arises, slow down or switch positions. Being responsive and attentive strengthens mutual trust and enjoyment.

Respect Above All: Having a large penis can be an advantage, but respecting your partner’s comfort and preferences is far more important.

6. Don’t Rely Solely on Size

Confidence is great—but don’t let size be your only strength.
What truly matters is sharing an enjoyable, respectful, and emotionally connected experience.

A large penis doesn’t guarantee satisfaction.
Kindness, attentiveness, and emotional intimacy are the most powerful tools for great sex.

Summary: Having a Big Penis Is Desirable, But Size Isn’t Everything

A large penis (kyokon) is often viewed as a symbol of sexual appeal and confidence, and many people admire or aspire to it.
While penis size can sometimes be a point of attention, it’s important to remember that size alone does not determine sexual satisfaction.

1. Sexual Satisfaction Doesn’t Depend Solely on Size

Numerous studies and real-life experiences show that the quality of sex is more influenced by partnership, communication, and mutual respect than by size.
Trust and emotional connection with your partner are the true foundations of satisfying intimacy.

2. Great Sex Is Possible Without a Large Penis

You don’t need to be well-endowed to please your partner.
Prioritizing foreplay, paying attention to your partner’s needs, and showing empathy can lead to deeply satisfying sex, regardless of size.
Technique and thoughtfulness often matter more than physical dimensions.

3. Confidence Is Key

No matter your size, confidence in yourself is essential.
Sexual confidence stems not just from appearance but from self-awareness and healthy relationships with your partner.
Being comfortable with yourself can lead to more positive and enjoyable experiences.

4. Don’t Rely on Extreme Size-Enhancement Methods

It’s natural to want to be bigger, but surgical procedures, supplements, or exercises should be approached with caution.
Rather than obsessing over increasing your size, focus on accepting yourself and improving other areas of attraction and connection.
That’s a much healthier—and more sustainable—path.

5. Communication Is the Most Important Factor

In the end, good communication with your partner is what matters most in sexual relationships.
Mutual respect, emotional safety, and open dialogue lead to true intimacy and fulfillment.

Whether or not you’re “big” doesn’t define your worth in a relationship. What truly matters is the quality of your connection with your partner.

Conclusion:

While having a large penis may be a dream for many men, true sexual satisfaction and confidence don’t come from size alone.
What matters most is having confidence in yourself and maintaining open, respectful communication with your partner so that both of you can enjoy intimate moments together.

Rather than stressing over size, focus on discovering and embracing your other unique strengths.
That’s what leads to real happiness and fulfilling sex.
