More Info


Understanding penis size is a topic that often comes with a lot of myths and misconceptions. Let's address your questions one by one, providing clarity based on medical knowledge.

1. Is an 11 cm penis size normal?
The average erect penis size is typically reported to be between 12 cm to 16 cm (approximately 4.7 to 6.3 inches). However, it's important to note that penis size can vary significantly among individuals. At 11 cm (about 4.3 inches), your size is slightly below the average range, but it is still within the normal spectrum. Many factors, including genetics and hormonal levels during puberty, influence penis size. It's also crucial to remember that penis size does not determine one's worth or ability to engage in sexual relationships successfully.

2. Until what age does penis size continue to grow?
Penis growth typically occurs during puberty, which can start as early as age 9 and continue until the late teens. Most males will experience significant growth in penis size between the ages of 12 and 16. By the age of 18, most males have reached their adult size, although some may continue to develop slightly into their early twenties. If you are currently in your second year of junior high school (around age 13-14), you may still experience some growth in size as you continue through puberty.

3. Does being overweight affect penis size?
Yes, being overweight can affect the perceived size of the penis. Excess fat in the pubic area can create a "hidden" effect, making the penis appear smaller than it is. This is not due to an actual reduction in size but rather because the fat pad can obscure part of the penis. Maintaining a healthy weight through a balanced diet and regular exercise can help in achieving a more favorable appearance. However, it is essential to focus on overall health rather than just aesthetics.


Additional Considerations:
- Myths about penis size: There are many myths surrounding penis size, including the belief that larger sizes correlate with better sexual performance or satisfaction. Research shows that sexual satisfaction is more closely related to emotional connection, communication, and technique rather than size.


- Self-esteem and body image: It's common for adolescents to feel self-conscious about their bodies, including penis size. It's essential to foster a positive body image and understand that everyone develops at their own pace. If you have concerns about your body or self-esteem, consider discussing them with a trusted adult or counselor.

- Health and hygiene: Regardless of size, maintaining proper hygiene is crucial for sexual health. Regular washing and care can prevent infections and promote overall well-being.

In conclusion, an 11 cm penis size is within the normal range, and you may still experience growth as you continue through puberty. Weight can affect the perceived size, but it is essential to focus on overall health and well-being rather than just size. If you have further questions or concerns, don't hesitate to reach out to a healthcare professional who can provide personalized advice.
