Penile issues


At 18 years old, I was previously overweight, but my weight is now at a normal level.
However, I still have some excess fat.
My body hair is sparse except for a significant amount around the penis and pubic area.
When not erect, my penis is about 4 cm long and is covered by the foreskin.
The length of my penis has not seemed to grow much over the years; it only becomes visible when erect, reaching about 10 cm.
I typically masturbate about once a day.
I would like to know if this is abnormal and if I need to see a doctor.
Does masturbation affect development? If it does, will stopping now lead to an increase in size?

Hello: It should be normal.
If you feel the need, you can seek medical advice.
Does masturbation affect development? --> It would be unwise if it does; will stopping now still allow for growth? --> It is unrelated.
Wishing you good health.

When it comes to penile development and concerns regarding size and growth, it is important to understand that there is a wide range of normal when it comes to male anatomy. However, if you are experiencing significant concerns about your development, it may be beneficial to seek medical advice.

At 18 years old, you are at the tail end of puberty, which is the period during which most males experience their most significant growth in terms of height, body composition, and sexual development. The average penis size varies widely, and many factors can influence this, including genetics, hormonal levels, and overall health. It is also important to note that the penis can appear smaller when not erect, which is completely normal.
From your description, it seems that you have some concerns about the size of your penis when flaccid (4 cm) and its ability to be fully exposed due to the presence of the foreskin. The fact that your penis measures about 10 cm when erect is within the average range, as studies suggest that the average erect penis size is approximately 12 to 16 cm.
Regarding your question about whether this is abnormal, it is essential to consider the context of your overall health and development. If you have not experienced any pain, discomfort, or other medical issues, it may simply be a variation of normal. However, if you feel that your development is significantly delayed or if you have other symptoms such as hormonal imbalances (e.g., lack of body hair, gynecomastia, etc.), it would be advisable to consult a healthcare professional.

As for the concerns about masturbation, it is a normal part of sexual development and does not negatively impact growth or development of the penis. Masturbation is a common behavior among adolescents and young adults, and it does not affect the size of the penis. If you are concerned about your habits or if you feel that it is interfering with your daily life or mental health, it may be worth discussing with a healthcare provider.

If you are considering seeking medical advice, it may be beneficial to consult with a urologist or an endocrinologist. These specialists can provide a thorough evaluation, including hormone level testing if necessary, and can help determine if there are any underlying issues that need to be addressed. They can also provide guidance on what to expect during and after puberty, as well as any potential treatments if there are concerns about development.

In summary, while your concerns are valid, it is essential to remember that there is a wide range of normal when it comes to penile size and development. If you feel that your development is significantly delayed or if you have other symptoms, seeking medical advice can provide clarity and reassurance. Remember that masturbation is a normal behavior and does not affect penile growth. If you have further questions or concerns, do not hesitate to reach out to a healthcare professional for personalized advice.
