Normal Penis Size: What Every Man Should Know - Urology

Disturbing issues


Hello, doctor.
I would like to ask what is the normal girth for a male penis.
My flaccid size is 5-6 cm in length and 2.9 cm in girth, which seems quite small to me.
When erect, it measures 12 cm in length and 3.6 cm in girth, which still feels thin.
I have used the "OK" method to check my testicles, and they seem to be just right, but they are noticeably smaller than average.
As I am about to enlist in the military, I am really struggling with this concern, especially since I accidentally saw a friend's penis, which appeared significantly larger.
I am worried about how I will handle this situation in the military.
Thank you, doctor.

Hello, you shouldn't worry too much about the size of your penis.
A small-scale study conducted by physicians in the country yielded the following results: however, since participation was voluntary, the results are for reference only and do not represent the true average size among the population (note: individuals with smaller sizes may be less willing to participate in measurements, which could skew the results to appear larger): http://www.libertytimes.com.tw/2003/new/mar/7/today-m3.htm You can refer to it yourself.
However, the size of the penis is not significantly related to sexual function, nor is it an absolute factor for future happiness.
I recall that during military service, individuals generally do not pay attention to others; everyone is focused on their own hygiene without noticing others.
It's similar to using certain public restrooms where people stand in a row; you typically do not pay special attention to the person next to you.
Unless you specifically look at others, most people do not observe others while showering.
If there are any unclear points, feel free to ask again, and we can discuss and research further.
Sincerely, Dr.
Hsu Wei-Kai, Director of Urology, Taitung Hospital, Department of Health, Executive Yuan.

Understanding normal penis size is a common concern among men, especially during adolescence and early adulthood when self-image and peer comparison are particularly pronounced. It's important to recognize that penis size can vary significantly among individuals, and what is considered "normal" encompasses a wide range of sizes.

Research indicates that the average erect penis size is approximately 5.1 to 5.5 inches (about 13 to 14 cm) in length and around 4.5 to 4.7 inches (about 11.5 to 12 cm) in circumference. For a flaccid penis, the average size is about 3.6 inches (9.16 cm) in length and around 3.6 inches (9.31 cm) in circumference. Based on these statistics, your measurements of 4.7 inches (12 cm) when erect and 2.9 inches (7.4 cm) in circumference are within the normal range, albeit on the smaller side.

It's crucial to understand that penis size does not determine a man's worth, masculinity, or ability to engage in sexual relationships. Many factors contribute to sexual satisfaction, including emotional connection, communication, and technique. Furthermore, concerns about size often stem from societal pressures and unrealistic portrayals in media rather than medical or scientific evidence.

Regarding your specific concerns about being seen in a communal setting, such as during military service, it's worth noting that many men share similar insecurities. The military environment often fosters camaraderie and mutual respect, and most individuals are more focused on their own experiences than on comparing sizes. Additionally, the emphasis in military training is on teamwork and discipline rather than physical attributes.

If you are feeling particularly anxious about this issue, consider discussing your feelings with a trusted friend or a mental health professional. They can provide support and help you work through any self-esteem issues related to body image. Remember, confidence and self-acceptance are key components of attractiveness and can significantly impact how others perceive you.

In summary, while penis size can be a source of concern for many men, it's essential to recognize that there is a wide range of what is considered normal. Focus on building confidence in yourself and your abilities rather than fixating on physical attributes. If you have ongoing concerns or feelings of inadequacy, seeking professional guidance can be beneficial.
