Concerns About STDs and Hygiene for Teen Boys: What You Need to Know - Urology

Share to:

I'm very scared... please help me, reply quickly... thank you?


Hello, I am a 14-year-old boy in junior high school.
I have no sexual experience, but I have experience with masturbation.
I want to know if this could lead to a sexually transmitted infection (STI).
After ejaculation, I use disinfectant alcohol to clean myself; is this problematic? I noticed that there are small flesh-colored bumps on the glans of my penis, and there is a single white bump under the glans.
It doesn't hurt, but my penis has an unusual odor.
I want to know if I have an STI.

Hello, little brother: You have entered puberty, and your sexual urges are awakening.
If you have no sexual experience and do not engage in masturbation, you may often experience nocturnal emissions.
Masturbation itself does not cause sexually transmitted infections.
After ejaculation, there is no need for disinfection or alcohol sanitization; it is advisable to drink a large glass of water and urinate shortly afterward, as this can be beneficial.
Generally speaking, small particles in the coronal sulcus are normal.
The white area you refer to beneath the glans is likely the location of the sebaceous glands, which are located on either side of the penile frenulum.
These glands produce smegma, which may be what you describe as white particles.
However, it is not certain; it resembles pearls, and you should check for any issues related to phimosis to confirm.

It's completely normal for a 14-year-old boy to have questions and concerns about sexual health, hygiene, and the possibility of sexually transmitted diseases (STDs), especially when navigating puberty and the changes that come with it. First and foremost, it's important to understand that having sexual experiences, including masturbation, does not inherently put you at risk for STDs unless you engage in sexual activities with a partner who may be infected. Since you mentioned that you do not have any sexual experience, your risk for STDs is currently very low.

Regarding your concerns about hygiene and the practices you mentioned, using alcohol or disinfectants on your genital area is not advisable. The skin in that area is sensitive, and using harsh chemicals can lead to irritation, dryness, or even infections. Instead, maintaining good hygiene involves washing the area gently with mild soap and water during your regular bathing routine. This will help keep the area clean without causing harm.

As for the small bumps you described on the glans (the head of the penis) and the white spot, it’s important to note that many young men experience various skin changes during puberty. These can include:
1. Pearly Penile Papules: These are small, harmless bumps that can appear around the corona (the ridge of the glans). They are normal anatomical variations and not a sign of disease.

2. Fordyce Spots: These are small, painless, pale bumps that can appear on the shaft of the penis and are simply enlarged oil glands. They are also completely normal.

3. Sebaceous Cysts: Sometimes, small white bumps can be sebaceous cysts, which are benign and often painless.

If the bumps are not causing you pain or discomfort, they are likely not a cause for concern. However, if you notice any changes in size, color, or if they become painful, it would be wise to consult a healthcare professional for a proper evaluation.

The odor you mentioned can be a result of a buildup of smegma, which is a combination of dead skin cells, oils, and other bodily fluids. Regular washing can help prevent this buildup and reduce any associated odor. If the odor persists despite good hygiene, or if you notice any unusual discharge or irritation, it would be advisable to see a doctor.

In summary, while it's good to be aware of your body and any changes, many of the concerns you have may be normal variations associated with puberty. If you ever feel uncertain or anxious about your health, don't hesitate to talk to a trusted adult or healthcare provider. They can provide you with accurate information and help ease your concerns. Remember, taking care of your body and maintaining good hygiene is essential, and seeking help when needed is a sign of maturity.
