Vaginal odor is a common occurrence, and several factors can contribute to it. While it is natural for the vagina to have a mild scent, certain conditions or activities can alter this smell. For instance, sex can cause a temporary change in vaginal odor due to the interaction of semen with vaginal fluid, which has a different pH level. Additionally, the use of lubricants and barrier protection can also influence the scent. Vaginal odor can vary throughout the menstrual cycle, with mid-cycle typically producing the most pronounced smell. Other factors that can affect vaginal odor include diet, bath products, underwear material, and hormonal changes. While most vaginal odors are harmless, a strong and persistent unpleasant smell accompanied by discharge, burning, or itching may indicate an underlying health issue such as bacterial vaginosis, trichomoniasis, or a yeast infection. In such cases, consulting a healthcare provider is recommended.

What You'll Learn
Yeast infections can cause a strong cheese smell
Vaginal odour is a common concern, and it's natural for the vagina to have a mild scent. The smell can vary depending on a woman's hygiene habits, diet, menstrual cycle, and other factors. While vaginal odour is usually fleeting and harmless, certain smells can indicate an infection. One such infection is bacterial vaginosis (BV), which is responsible for the fishy smell often associated with unpleasant vaginal odours. Another common vaginal infection is trichomoniasis, a sexually transmitted infection that can cause a fishy or musty odour.
Yeast infections are another common cause of vaginal odour. While some women may notice a sweet smell or a yeasty odour similar to beer or bread, others may experience a strong cheese smell. This is because the infection can lead to a change in vaginal discharge, which can become lumpy, white, and thick, resembling cottage cheese. The presence of this type of discharge, along with symptoms such as itching, burning, and dryness, can indicate a yeast infection.
It is important to note that most vaginal odours are normal and can be influenced by various factors such as diet, stress, and hygiene. However, if an unusual or strong odour persists or is accompanied by other symptoms, it is recommended to consult a healthcare professional for proper diagnosis and treatment.
While there is no direct mention of sex smelling like Parmesan cheese, it is possible that the odour described could be related to a yeast infection or other vaginal infections. It is always advisable to seek medical advice if you have concerns or notice any unusual changes in vaginal odour or discharge.
In summary, yeast infections can cause a strong cheese-like smell due to the change in vaginal discharge associated with the infection. This odour may be more noticeable after sex, as intercourse can alter vaginal pH levels and affect how the vagina smells temporarily. However, if the odour persists or is accompanied by other symptoms, it is important to consult a healthcare provider.

Semen can cause a change in vaginal pH and odour
While there are some reports of sex smelling like Parmesan cheese, baby vomit, or other strange scents, this is not a common occurrence and could be due to a variety of factors, such as poor hygiene, yeast infections, or bacterial vaginosis.
Now, onto the topic of semen and vaginal pH and odour:
Semen is alkaline, with a pH level ranging from 7.1 to 8, while a healthy vagina is slightly acidic, with a pH balance of 3.8 to 4.5. This pH balance is crucial for maintaining the growth of healthy bacteria, known as "vaginal flora", specifically Lactobacilli, and preventing the overgrowth of harmful bacteria that can cause infections.
When semen is introduced to the vaginal canal during unprotected penetrative sex, it can temporarily alter the vaginal pH, creating a more alkaline environment to protect the sperm and encourage fertilization. This change in pH can also affect the odour of the vagina. While this rise in pH is beneficial for conception, it can increase the risk of infection as it disrupts the delicate balance of vaginal flora. Certain bacteria, such as yeast and those that cause bacterial vaginosis (BV), thrive in a less acidic environment and can lead to infections, causing a change in odour as well.
It is important to note that other factors can also influence vaginal pH and odour, including diet, stress, hormones, gut health, and the use of certain products. Maintaining a healthy vaginal pH and preventing infections can be supported by practices such as wearing cotton underwear, using unscented and unflavoured lubricants, and peeing after sex to flush out semen.

Trichomoniasis is an STI that can cause a fishy smell
While sex itself does not smell like parmesan cheese, changes in vaginal pH levels due to various factors, such as semen, saliva, or sweat, can cause temporary changes in vaginal odour after sex.
Trichomoniasis and Fishy Smell
Trichomoniasis, or trich, is a common sexually transmitted infection (STI) caused by a parasite called Trichomonas vaginalis. This parasite can infect both men and women, and is passed between people during genital contact, including vaginal sex. Trichomoniasis is known to cause a foul-smelling, fishy vaginal odour, which is often described as a very distinct, putrid smell. The infection can also lead to other symptoms, such as abnormal vaginal discharge, genital itching, and painful urination.
The parasite infects the lower genital tract, including the vulva, vagina, cervix, and urethra in women, and the inside of the penis (urethra) in men. Trichomoniasis can cause irritation in the genital area, making it easier for other STIs to enter the body or be passed on to others. It is important to note that trichomoniasis can be effectively treated with antibiotics, and it is recommended to seek medical attention if any unusual symptoms or odours are noticed.
In addition to trichomoniasis, other factors can also cause changes in vaginal odour. These include diet, menstrual cycle, bath products, underwear, and vaginal pH levels. It is normal for the vagina to have a mild odour, and temporary vaginal odour changes are common and often resolve on their own. However, if an unpleasant odour persists or is accompanied by other symptoms, it is recommended to consult a healthcare provider.

Vaginal pH levels can be altered by oral sex
Vaginal pH levels typically range from 4.0 to 4.5 during a woman's reproductive years. This acidity is maintained by lactobacilli bacteria, which secrete lactic acid and hydrogen peroxide. A healthy vaginal pH level is essential for maintaining vaginal health and protecting against bacterial and fungal infections.
Oral sex can introduce saliva, which contains digestive enzymes and bacteria, into the vagina. This can alter the vaginal pH balance and, consequently, cause a change in smell. While this change in odour is typically temporary and harmless, it is important to note that oral sex can also facilitate the exchange of bodily fluids, potentially leading to the growth of certain bacteria and the development of infections.
The introduction of semen during penetrative sex can also temporarily alter the vaginal pH and odour due to its alkaline nature, contrasting with the vagina's typically acidic environment. Vaginal pH levels can further be influenced by various factors, including menstrual blood, infections, and practices such as douching or the use of scented hygiene products.
It is important to maintain a healthy vaginal pH balance to prevent infections and maintain overall vaginal health. Barrier protection methods, such as condoms or dental dams, can help prevent the exchange of bodily fluids and the disruption of vaginal pH levels. Additionally, practising good vaginal hygiene, avoiding harsh soaps and scented products, and staying hydrated can contribute to maintaining a healthy vaginal pH.
While most vaginal odours are harmless, some may indicate underlying health issues. For example, a fishy smell may be indicative of bacterial vaginosis or trichomoniasis, a sexually transmitted infection. A strong ammonia smell may be a sign of dehydration, and a persistent unpleasant odour could signal an underlying condition requiring medical attention.

Vaginal odour can be caused by bacterial vaginosis
Vaginal odour is usually a mild scent and can vary according to a woman's menstrual cycle, sex life, and lifestyle. However, a strong, unpleasant vaginal odour may be indicative of an underlying health problem.
Bacterial vaginosis (BV) is a common vaginal infection caused by an imbalance in the bacteria that live in the vagina. This imbalance occurs when "bad" bacteria (anaerobes) grow more quickly than "good" bacteria (lactobacilli), resulting in bacterial overgrowth. Lactobacilli are the same "good bacteria" found in yogurt and help protect the vagina from an overgrowth of bad bacteria that can cause infections.
BV is responsible for the fishy smell most commonly associated with unpleasant vaginal odours. The fishy smell may be especially strong after sex. Other common symptoms of BV include a gray or grayish-white discharge, vaginal itching or irritation, and a burning feeling when urinating. While BV is not considered a sexually transmitted infection (STI), it is linked to sexual activity as sex can change the bacterial environment in the vagina, making bacterial overgrowth more likely.
BV is easily treatable with antibiotics from a healthcare provider. To determine the cause of the abnormal vaginal odour, a healthcare provider will take a sample of the discharge, perform a vaginal exam, and check the vaginal pH level. Antibiotics such as clindamycin (Cleocin®) are commonly prescribed to clear up infections that cause unpleasant vaginal odours.
