Inquiry about semen after masturbation?


Hello, doctor.
After I masturbated and took a shower tonight, I noticed some white, flaky substances when I pulled back my foreskin to wash.
Is this something that happens to semen when it dries, or is it what they call smegma online? Also, after rinsing, the glans still had a layer of white-gray film on it.
Is that normal? I was able to wash it off slowly with water, but the water pressure was a bit strong and it felt slightly painful.
I applied some iodine; is that okay?
Additionally, I would like to ask if semen is generally slightly yellow and sticky.
When it was on the wooden floor, it looked milky white, but when I wiped it with tissue, it appeared a bit yellowish and somewhat phlegm-like, not watery.
I'm a bit worried if this could indicate some disease, but I don't have any pain or burning sensation, so I'm unsure if this is normal or if there is inflammation that requires a doctor's visit.
I usually masturbate about once every one to two weeks, and the amount seems quite substantial.
I was surprised to see the color change this time.
Sorry for the many questions, and thank you for your help, doctor.

Hello, the white flaky substance may sometimes indicate a fungal infection.
When cleaning, it is important not to use iodine, and to be gentle, as the mucous membranes are delicate and can easily be injured.
If injured, the wound is more susceptible to inflammation due to moisture being trapped.
Therefore, after cleaning, it is essential to dry the area thoroughly.

Regarding the color of the semen, based on your description, it seems to be normal.
In some cases, yellowish semen can be associated with pelvic pain and inflammation, but your description does not suggest this issue.
If you are still concerned, it is advisable to consult a urologist for a semen analysis and discuss the results with your physician.

Understanding changes in semen and genital hygiene after masturbation can be a source of concern for many individuals. Let's break down your questions and concerns regarding the observations you've made post-masturbation.

Firstly, the white, flaky substance you noticed after pulling back your foreskin could likely be smegma, which is a combination of dead skin cells, oils, and other bodily secretions that can accumulate under the foreskin. It is a normal occurrence for uncircumcised males, especially if proper hygiene is not maintained. Smegma can appear as a whitish or yellowish substance and is generally harmless, but it is essential to clean the area regularly to prevent any potential irritation or infection.

Regarding the grayish-white film you observed on the glans (the head of the penis), this is also typically normal. The glans can sometimes have a natural coating of cells and oils that can appear as a thin layer. Regular washing with warm water should help remove this without causing discomfort. If you experience pain or irritation when washing, it may be a sign that you are using too much pressure or that the area is sensitive. It’s advisable to be gentle and avoid using harsh soaps or scrubs, as these can irritate the sensitive skin.

As for the pain you felt when rinsing with water, it’s essential to ensure that the water pressure is not too strong, as this can cause discomfort. If you find that washing causes pain consistently, it might be worth consulting a healthcare professional to rule out any underlying issues.

You mentioned applying iodine to the area. While iodine is an antiseptic, it is not typically recommended for use on sensitive areas like the genitalia unless advised by a healthcare provider. It can cause irritation or an allergic reaction in some individuals. If you have concerns about cleanliness or potential infection, it’s best to consult a doctor for appropriate treatment options.

Regarding the appearance of your semen, it is normal for semen to vary in color and consistency. Healthy semen can range from a milky white to a slightly yellowish tint. The yellowish hue you observed could be due to several factors, including diet, hydration levels, or the presence of certain substances in your body. Semen is typically viscous and can appear thicker or more gelatinous at times. If you are not experiencing any pain, burning sensation, or other unusual symptoms, this variation is likely normal.

However, if you notice any significant changes in your semen's color, consistency, or volume, or if you start experiencing discomfort, pain, or any other concerning symptoms, it would be prudent to seek medical advice. A healthcare provider can perform a thorough examination and, if necessary, conduct tests to rule out any infections or other conditions.

In summary, the changes you are observing are likely normal variations associated with semen and genital hygiene. Maintaining good hygiene practices, being gentle when cleaning the area, and monitoring for any unusual symptoms are essential steps. If you have ongoing concerns or notice any significant changes, do not hesitate to consult a healthcare professional for personalized advice and reassurance.
