"Dick cheese" is a slang term for smegma, a whitish or yellowish material that can collect around the penis, particularly underneath the foreskin in uncircumcised men, though it can happen to anyone.
Despite the unpleasant nickname, smegma itself is not usually an infection or sexually transmitted infection (STI/STD). It is primarily a buildup of natural body substances, including shed skin cells, oils, sweat, and other fluids.
Small amounts of smegma are generally harmless. Allowing it to accumulate can contribute to odor and irritation and create an environment where bacteria or yeast can grow.
What Is Dick Cheese?
The medical term for dick cheese is smegma.
Smegma is generally:
-
White, off-white, or yellowish
-
Thick or paste-like
-
Sometimes crumbly or cheese-like
-
Most commonly found underneath the foreskin
-
Capable of developing a noticeable odor when it accumulates
It consists largely of dead skin cells, natural skin oils, sweat, and other bodily fluids.
Smegma is therefore not pus, semen, or necessarily a sign of disease.
People sometimes assume that any white material underneath the foreskin must be a yeast infection or STI, but normal smegma can have a similar appearance. Symptoms such as significant redness, pain, itching, swelling, sores, or urethral discharge make an infection or another condition more important to consider.
Why Does Smegma Form?
Skin continuously sheds cells and produces natural oils. In areas where skin folds against itself, these substances can accumulate rather than being immediately washed away.
The space between the foreskin and glans of an uncircumcised penis is particularly suited to this process.
Smegma formation can be increased by:
-
Infrequent genital washing
-
Difficulty retracting the foreskin
-
Sweat and moisture
-
Residual urine
-
Naturally oily skin
-
Long periods without cleaning underneath the foreskin
A warm, moist environment underneath the foreskin can also encourage bacterial or fungal growth when material is allowed to accumulate.
Is Dick Cheese Normal?
Some smegma production is normal.
Its presence does not automatically mean someone is dirty, has an infection, or has an STI. Smegma develops from substances that the skin normally produces.
What matters more is whether it is regularly removed before a significant buildup develops.
Large or persistent accumulations are more likely to cause odor, irritation, or difficulty keeping the area clean.
Does Dick Cheese Smell?
It can.
Fresh smegma may have relatively little odor, but accumulated smegma can develop a strong or unpleasant smell.
This happens partly because the material contains oils, dead skin, sweat, and moisture. When it remains underneath the foreskin, bacteria can metabolize some of these substances and contribute to odor.
A persistent foul smell accompanied by pain, redness, swelling, itching, or abnormal discharge should not automatically be blamed on smegma. Those symptoms can occur with balanitis, yeast infections, bacterial infections, and some STIs.
How to Get Rid of Dick Cheese
In uncomplicated cases, the treatment is straightforward: gently wash away the accumulated smegma.
For someone with a retractable foreskin:
-
Gently pull the foreskin back.
-
Rinse the glans and underneath the foreskin with warm water.
-
Gently remove visible buildup.
-
Dry the area carefully.
-
Return the foreskin to its normal position.
Do not aggressively scrape dried smegma from sensitive penile tissue. If the material has hardened or adhered to the skin, warm water can help soften it before gentle removal.
Strongly scented soaps, antiseptics, alcohol-based products, and aggressive scrubbing are generally unnecessary and can irritate genital skin. Excess friction can also irritate penile tissue; VB Health has a separate guide to friction burn on the penis.
Can You Prevent Smegma?
Regular hygiene is usually sufficient.
For uncircumcised men, this means gently retracting the foreskin during bathing and cleaning underneath it.
Other useful habits include:
-
Washing regularly
-
Drying the area after bathing
-
Changing sweaty underwear
-
Avoiding prolonged moisture around the genitals
-
Avoiding harsh cleansers on sensitive penile skin
-
Cleaning underneath the foreskin after substantial buildup becomes noticeable
Overwashing is not necessarily better. Frequent exposure to strong soaps or excessive scrubbing can itself cause irritation and inflammation.
Smegma in Uncircumcised Men
Smegma is much more noticeable in people with a foreskin because material can become trapped between the foreskin and the head of the penis.
The foreskin creates a protected, relatively moist space. Normally, this is not a problem when it can be retracted and cleaned.
Problems are more likely when:
-
The foreskin cannot be fully retracted
-
Cleaning underneath it is difficult
-
Significant moisture remains trapped
-
Smegma is allowed to accumulate for long periods
A tight foreskin that cannot be pulled back is known as phimosis. Trying to forcibly retract a foreskin that does not move comfortably can cause injury, so persistent difficulty retracting it should be evaluated by a healthcare professional.
For more background on foreskin and circumcision terminology, see VB Health’s guide to what “uncut” means.
Can Circumcised Men Get Dick Cheese?
Yes, although significant smegma accumulation is considerably less likely.
Without a foreskin, there is no enclosed space around the glans in which smegma can easily collect. Dead skin, sweat, oils, and genital secretions can still accumulate around the penis, particularly within skin folds.
Routine washing generally prevents noticeable buildup.
VB Health also covers the terminology and health considerations surrounding circumcision and being “cut”.
Does Smegma Cause Balanitis?
Smegma itself is not the same thing as balanitis.
Balanitis means inflammation of the glans, or head, of the penis. If the foreskin is also inflamed, the condition is called balanoposthitis.
Substantial smegma accumulation can contribute to the conditions that allow balanitis to develop.
The warm and moist environment underneath a foreskin can promote the growth of microorganisms, particularly when urine, sweat, discharge, and smegma accumulate. Candida yeast is one of the most frequently identified infectious causes of balanitis.
Symptoms of balanitis can include:
-
Redness
-
Swelling
-
Pain or tenderness
-
Itching
-
Unpleasant odor
-
Discharge
-
Difficulty retracting the foreskin
Is Dick Cheese a Yeast Infection?
Not necessarily.
Both smegma and a penile yeast infection can produce whitish material around the penis, which makes them easy to confuse.
Smegma by itself generally does not cause significant inflammation. A Candida infection is more likely to produce additional symptoms such as:
-
Redness
-
Burning
-
Itching
-
Tenderness
-
Swelling
-
Irritated or shiny skin
-
Thick discharge or exudate
If the area remains inflamed despite normal washing, an infection or skin condition should be considered rather than repeatedly scrubbing the penis.
Is Smegma an STI?
No.
Smegma itself is not sexually transmitted.
It is produced from substances already present on the body.
Some sexually transmitted infections can cause genital discharge, irritation, sores, or inflammation that may initially be mistaken for smegma.
Medical evaluation is particularly appropriate if there is:
-
Discharge coming directly from the urethral opening
-
Pain or burning during urination
-
Genital sores or blisters
-
Significant redness or swelling
-
Recent sexual exposure that creates concern about an STI
Balanitis itself is also not classified as an STI, although sexually transmitted organisms can sometimes cause penile inflammation.
Is Smegma Dangerous?
Usually not.
Normal smegma is generally considered harmless when it is regularly cleaned away.
The problems associated with substantial buildup are mostly secondary effects, such as irritation, odor, and creating an environment favorable to microbial growth.
Older theories also suggested that smegma itself might cause penile cancer. Current reviews do not support smegma itself as a carcinogen or direct cause of penile cancer.
Chronic inflammation and certain other conditions affecting the penis can carry different risks, which is one reason persistent penile lesions or inflammation should be medically evaluated rather than assumed to be smegma.
Can Women Get Smegma?
Yes.
Although the slang term "dick cheese" refers specifically to penile smegma, smegma is not exclusive to men.
In women, similar material can accumulate around the vagina:
-
Around the clitoris
-
Underneath the clitoral hood
-
Within folds of the labia
It is composed of the same general mixture of oils, dead skin cells, sweat, and other fluids.
Normal genital secretions should also be distinguished from abnormal discharge. VB Health has a separate overview of vaginal discharge and signs that it may be abnormal.
As with penile smegma, gentle washing is generally sufficient to prevent significant buildup.
Should You Use Soap Under the Foreskin?
Usually, plain warm water is enough for cleaning sensitive tissue beneath the foreskin.
Some people tolerate mild soap without problems, but strongly scented soaps, shower gels, antibacterial cleansers, and similar products can irritate the glans and foreskin.
If a cleanser causes burning, dryness, redness, or irritation, discontinue it.
When Should You See a Doctor?
Smegma that disappears after ordinary washing usually requires no medical treatment.
Medical evaluation is appropriate when there are additional symptoms or the problem keeps returning despite reasonable hygiene.
See a healthcare professional if you develop:
-
Persistent redness or swelling
-
Significant penile pain
-
Severe itching or burning
-
Sores, ulcers, or blisters
-
Urethral discharge
-
Painful urination
-
Persistent foul odor despite washing
-
Difficulty retracting the foreskin
-
Inability to return a retracted foreskin to its normal position
-
Recurrent balanitis
Repeated balanitis can sometimes occur in association with conditions such as diabetes, so recurrent episodes warrant proper evaluation rather than repeatedly treating the symptoms at home.
What to do
“Dick cheese” is simply a colloquial name for smegma, a mixture of dead skin cells, natural oils, sweat, and other fluids that can accumulate around the penis.
Smegma itself is usually harmless and is neither an STI nor automatically evidence of an infection.
The simplest way to prevent it is regular, gentle genital hygiene, particularly cleaning underneath a retractable foreskin.
If white buildup occurs together with redness, itching, pain, swelling, sores, or abnormal discharge, the problem may be something other than ordinary smegma and should be evaluated appropriately.
