The tip of the glans appears white after an erection?


Recently, I have been experiencing frequent masturbation, and one day I noticed that the tip of my glans appears completely white and feels dry after an erection.
However, this does not occur when I am not erect.
I am unsure if this is a medical condition or if it is related to my frequent masturbation.
Additionally, today I noticed that when I am not erect, there is a small area on the glans that looks like a small scar.
I would like to know the possible causes of this.
Thank you, doctor.

More Info


The observation of white discoloration on the glans (the head of the penis) after an erection can be concerning, especially if it is a new development. There are several potential explanations for this phenomenon, and understanding the underlying causes is essential for determining whether medical intervention is necessary.

Firstly, the white discoloration you are experiencing could be related to a condition known as "lichen sclerosus." This is a chronic inflammatory skin condition that can affect the genital area, leading to white patches, dryness, and sometimes discomfort. It is more common in men and can be exacerbated by friction or irritation, which may occur with frequent masturbation. If this condition is suspected, it is advisable to consult a healthcare professional for a proper diagnosis and treatment options.

Another possibility is that the white discoloration is due to a temporary change in blood flow and skin hydration during an erection. When the penis becomes erect, blood flow increases, and the skin may appear paler or whiter due to the engorgement of blood vessels. If this discoloration resolves shortly after the erection subsides and is not accompanied by pain or other symptoms, it may not be a cause for concern.

However, if the white discoloration persists, is accompanied by pain, itching, or any other unusual symptoms, it could indicate a more serious condition, such as a fungal infection or a sexually transmitted infection (STI). Conditions like balanitis, which is inflammation of the glans, can also lead to changes in color and texture. Infections can cause irritation and may require antifungal or antibacterial treatment.

Regarding the small scar-like area you mentioned, it could be a result of previous trauma, friction, or irritation from sexual activity or masturbation. Scarring can occur if the skin has been repeatedly irritated or injured. If this area is not painful and does not change in appearance, it may not be a significant concern. However, if you notice changes in size, color, or if it becomes painful, it is essential to seek medical advice.

In summary, while occasional changes in the appearance of the glans can be normal, persistent or concerning symptoms warrant a visit to a healthcare provider. They can perform a physical examination, take a detailed history, and possibly conduct tests to determine the underlying cause of your symptoms. It is crucial to address any concerns you have about your sexual health, as early intervention can lead to better outcomes and peace of mind.
Additionally, practicing good hygiene, using lubrication during masturbation, and avoiding excessive friction can help prevent irritation and maintain the health of the genital area. If you have any further questions or if your symptoms worsen, do not hesitate to reach out to a healthcare professional for personalized advice and treatment.
