Sexual development issues


Hello doctor, I am 18 years old.
I have pubic hair and armpit hair, and I have had a habit of masturbation since middle school.
I also have semen and an erection size of 11 centimeters, with a normal frequency.
However, my penis does not appear to be erect like that of an infant.
What could be the possible reasons for this?

Hello: It's normal for individuals to have variations when not erect, so there's no need for concern.
If you're still worried, you can consult a urologist at a hospital.
Wishing you good health.

Understanding sexual development issues in young adults can be complex, especially during the transitional phase of adolescence into adulthood. At 18 years old, you are at a critical point in your sexual development, and it is normal to have questions and concerns about your body and its changes.

Firstly, regarding your concern about the size and appearance of your penis when flaccid, it is important to understand that there is a wide range of normal when it comes to penis size and appearance. The penis can vary significantly in size and shape among individuals, and many factors can influence its appearance when not erect. Genetics, hormonal levels, and overall body composition all play a role. It is also worth noting that the penis can appear smaller when flaccid due to temperature, anxiety, or even the position of your body.
The fact that you have developed pubic and underarm hair, as well as experiencing erections and ejaculation, indicates that you are undergoing normal sexual maturation. The average size of an erect penis is typically between 5 to 6 inches, and it is not uncommon for the flaccid size to appear smaller in comparison. If you are experiencing normal erections and ejaculation, this suggests that your sexual development is progressing appropriately.

If you are concerned about the appearance of your penis or if you feel that it is not developing as it should, it may be beneficial to consult with a healthcare professional. They can provide a thorough evaluation and determine if there are any underlying medical issues that need to be addressed. Conditions such as hormonal imbalances or developmental disorders can sometimes affect sexual development, but these are relatively rare.

Regarding your history of masturbation, it is a common and normal behavior among young adults. Masturbation does not negatively impact sexual development or function. In fact, it can be a healthy way to explore your body and understand your sexual responses. Concerns about frequency or its effects on energy levels are often overstated; as long as it does not interfere with your daily life or responsibilities, it is generally considered a normal part of sexual health.

It is also essential to address any feelings of anxiety or self-consciousness you may have about your body. Many young adults experience insecurities during this time, and it is crucial to remember that everyone develops at their own pace. Open discussions with trusted friends or family members, or seeking support from a mental health professional, can help alleviate feelings of inadequacy.

In conclusion, your experiences and concerns are valid and shared by many young adults. It is essential to focus on your overall health and well-being rather than solely on physical attributes. If you have ongoing concerns about your sexual development, do not hesitate to reach out to a healthcare provider for guidance and support. They can help you navigate these changes and provide reassurance about your development. Remember, sexual health is an integral part of overall health, and seeking information and support is a positive step towards understanding your body better.
