Genital size and urine volume?


I am 17 years old and have a habit of masturbation that is somewhat frequent.
My penis measures about 5 to 6 cm when flaccid and about 9 to 10 cm when erect.
Is this within the normal range? Are there any methods to increase hardness or length? I also tend to urinate quickly; is this related to my water intake or bladder size? Thank you for your response.

Hello: To address your question about frequent urination, it can be related to your fluid intake and bladder capacity, which are influenced by individual physiology.
However, it is important to ensure that your water intake is not too low.
Try to avoid sugary drinks and alcohol.
Daily exercise is essential for maintaining a healthy body.
Regarding the size of your genitalia, it is within normal limits.
If you wish to enhance length and firmness, excluding congenital factors, ensure you get adequate sleep and proper nutrition (focus on healthy eating and avoid fried and spicy foods).
Additionally, moderate exercise can provide opportunities for development.
Thank you for your inquiry (do what you can on your own, and be cautious of miraculous methods promoted in the market—no matter how extravagant the claims may be).

When it comes to concerns about penis size and sexual health, it's important to understand that there is a wide range of what is considered "normal." Based on the information you've provided, your penis size—approximately 5-6 cm when flaccid and 9-10 cm when erect—falls within the typical range for males, especially at your age of 17. Research indicates that the average erect penis size is around 12-16 cm, but significant variations exist, and many factors can influence these measurements, including genetics and hormonal levels during puberty.

Regarding your question about methods to increase penis size or hardness, it's crucial to approach this topic with caution. Many products and techniques advertised for penis enlargement, such as pills, pumps, or surgeries, often lack scientific backing and can potentially be harmful. The best way to ensure healthy erectile function is to maintain a healthy lifestyle, which includes regular exercise, a balanced diet, adequate hydration, and avoiding smoking or excessive alcohol consumption. If you are concerned about erectile hardness, it may be beneficial to consult a healthcare professional who can provide personalized advice and check for any underlying health issues.

As for your urination habits, frequent urination can indeed be influenced by your fluid intake. If you are not drinking enough water, your body may be signaling you to urinate more often, especially if you are consuming diuretics like caffeine. It's generally recommended for adolescents to drink at least 1.5 to 2 liters of water daily, depending on activity levels and climate. If you notice that your urination is consistently rapid or if you experience discomfort, it may be worth discussing with a healthcare provider to rule out any urinary tract issues or other medical conditions.

In summary, your penis size appears to be within a normal range for your age, and focusing on a healthy lifestyle is the best approach to maintaining sexual health. If you have ongoing concerns about your sexual health, urination, or any discomfort, seeking advice from a healthcare professional is always a good step. They can provide you with the most accurate information and help address any specific issues you may be facing. Remember, open communication with a doctor can help alleviate concerns and provide clarity on what is normal for you.
