The Science of Vaginal Lubrication: A Biological Journey


Vaginal lubrication is an essential component of a vulva-havers sexual health and reproductive functioning. It is a natural biological process that occurs in response to sexual arousal, ensuring pleasurable and comfortable sexual experiences while also helping to protect the delicate tissues within the vagina. Despite its importance, the science behind vaginal lubrication remains a mystery to many. In this blog post, however, we will delve into the biological process of vaginal lubrication, exploring its triggers, composition, and function, as well as addressing common misconceptions.


The Role of Sexual Arousal

Sexual arousal is the primary trigger for vaginal lubrication. It is a complex process that involves a combination of psychological and physiological factors, including visual, auditory, and tactile stimuli, as well as hormonal influences. When a vulva-haver becomes aroused, her body undergoes a series of changes, including increased blood flow to the genital area, which in turn leads to the production of vaginal lubrication.


The Greater and Lesser Vestibule Glands

Two small glands play a crucial role in vaginal lubrication: the Greater Vestibule glands, (AKA Bartholin's Glands) located on either side of the vaginal opening, and the lesser vestibule glands (aka Skene's glands), found near the urethra. When stimulated by arousal, these glands secrete fluids that contribute to the overall lubrication of the vagina. The Greater Vestibule glands produce a clear, viscous fluid, while the Lesser Vestibule glands release a thinner, more watery substance. Together, these secretions form the basis of vaginal lubrication.


Transudation and the "Sweating" Vagina

In addition to the fluids produced by the Lesser and Greater Vestibule glands, another significant source of vaginal lubrication is a process called transudation. During arousal, the increased blood flow to the vaginal walls causes plasma to seep through the porous tissue, creating a clear, slippery fluid. This phenomenon is sometimes referred to as the "sweating" vagina. The combination of fluids from the glands and transudation results in the lubrication needed for comfortable and pleasurable sexual activity.


Composition of Vaginal Lubrication

Vaginal lubrication is primarily composed of water, but it also contains various proteins, enzymes, electrolytes, and other substances that contribute to its unique properties. Some of these components include:

  1. Mucins: These proteins give vaginal lubrication its characteristic viscosity and help it adhere to the vaginal walls, providing long-lasting lubrication.

  2. Lactobacilli: These beneficial bacteria create an acidic environment within the vagina, which helps maintain a healthy vaginal ecosystem and protect against infections.

  3. Glycoproteins: These compounds assist in retaining moisture and contribute to the lubricating properties of the fluid.

  4. Enzymes: Enzymes such as lysozyme and lactoferrin provide antimicrobial protection, further safeguarding the vagina from infections.

The Importance of Vaginal Lubrication

Vaginal lubrication serves several essential functions during sexual activity, including:

  1. Comfort and pleasure: By reducing friction, lubrication helps make sexual activity more comfortable and pleasurable for both partners.

  2. Protection: The lubricating fluid helps protect the delicate vaginal tissues from damage caused by friction during intercourse. It also acts as a barrier, preventing the entry of harmful pathogens that could lead to infection.

  3. Facilitation of sperm transport: Vaginal lubrication plays a role in supporting sperm survival and transport, aiding in the process of fertilization.

Misconceptions and Common Issues

Despite its critical role in sexual health, there are several misconceptions about vaginal lubrication that can lead to misunderstandings or problems.

  1. Amount of lubrication as a measure of arousal: While arousal

  2. All lubrication is the same: Vaginal lubrication can vary in consistency, color, and odor, depending on factors such as a vulva-haver's menstrual cycle, hormonal fluctuations, and overall health. It's essential to understand that these variations are normal and not necessarily indicative of a problem.

  3. Vaginal dryness is always a sign of a lack of arousal: While insufficient lubrication can be due to a lack of arousal, there are other factors that can contribute to vaginal dryness, such as hormonal changes (e.g., menopause), certain medications, dehydration, or health conditions. It's important not to assume that vaginal dryness is solely related to arousal levels.

  4. Lubrication is the only indicator of arousal: Sexual arousal is a complex process involving both psychological and physiological responses. While lubrication is one manifestation of arousal, it is not the only one. A vulva-haver may experience other signs of arousal, such as increased heart rate, flushed skin, or erect nipples, even if she doesn't produce copious amounts of lubrication.

  5. Artificial lubricants are not necessary: In some cases, a vulva-haver may not produce enough natural lubrication to make sexual activity comfortable or pleasurable. In these situations, using artificial lubricants can significantly enhance comfort and reduce the risk of injury. It's crucial to recognize that using lubricants is a normal and healthy part of sexual activity for many couples.

  6. Vaginal lubrication is a sign of promiscuity or immorality: This misconception stems from cultural biases and misinformation. Vaginal lubrication is a natural biological process that occurs in response to sexual arousal and is essential for maintaining sexual and reproductive health. It is not a reflection of a vulva-haver's morality or character.

Understanding and addressing these misconceptions about vaginal lubrication can help foster better communication between partners, promote sexual health, and ultimately enhance the overall sexual experience.

Arousal Non-Concordance: A Complex Relationship Between Mind and Body

Arousal non-concordance refers to the phenomenon where a person's subjective experience of sexual arousal does not align with their physiological responses, such as genital blood flow or lubrication in women, or penile erection in men. In other words, arousal non-concordance occurs when the mind and body seem to be out of sync in terms of sexual arousal.


The concept of arousal non-concordance challenges the widely-held belief that physiological responses are always accurate indicators of a person's mental state or desire for sexual activity. Understanding arousal non-concordance is essential for promoting healthier and more accurate communication around sexual consent, as well as for addressing misconceptions about sexual desire and arousal.

Why Does Arousal Non-Concordance Occur?

The reasons behind arousal non-concordance can be complex and multifaceted. Some possible explanations include:

  1. Dual Control Model: This model proposes that sexual arousal is regulated by two separate systems – the sexual excitation system (SES) and the sexual inhibition system (SIS). The SES is responsible for increasing arousal in response to sexually relevant stimuli, while the SIS acts to decrease arousal in the presence of potential threats or negative consequences. Arousal non-concordance may occur when these systems are not working in harmony, leading to a disconnect between subjective and physiological arousal.

  2. Conditioning: Individuals may become conditioned to respond physiologically to specific stimuli, even if they do not find them subjectively arousing or desirable. For example, exposure to certain types of pornography or other sexual content may lead to a physiological response without necessarily evoking a corresponding subjective arousal.

  3. Stress and Anxiety: High levels of stress or anxiety can interfere with the brain's ability to accurately interpret and respond to sexual stimuli, leading to arousal non-concordance. In some cases, the body may respond physiologically to sexual stimuli while the mind remains preoccupied with stress or anxiety, creating a disconnect between subjective and physiological arousal.

Arousal non-concordance can manifest in various ways, including situations where a person feels mentally aroused but experiences little to no physiological response, such as vaginal lubrication in women. This disconnect can lead to confusion, frustration, or feelings of inadequacy for both the individual experiencing it and their partner. It's essential to understand that arousal non-concordance is a common and normal part of human sexuality, and there are several factors that can contribute to this phenomenon.


Factors Contributing to Arousal Non-Concordance with Lubrication

  1. Hormonal fluctuations: Hormones play a crucial role in regulating sexual response, including vaginal lubrication. Changes in hormone levels, such as those that occur during menstruation, pregnancy, or menopause, can impact the body's ability to produce lubrication, even in the presence of subjective arousal.

  2. Medications and medical conditions: Certain medications, such as antidepressants, antihistamines, or hormonal contraceptives, can impact vaginal lubrication. Additionally, medical conditions like Sjögren's syndrome, which affects the body's ability to produce moisture, can lead to vaginal dryness despite feelings of arousal.

  3. Dehydration: Dehydration can negatively affect the body's ability to produce adequate lubrication, creating a disconnect between mental arousal and physical response.

  4. Stress and anxiety: High levels of stress or anxiety can interfere with the body's ability to respond appropriately to sexual stimuli, leading to a discrepancy between subjective arousal and physiological responses like lubrication.

  5. Incomplete arousal process: In some cases, a woman may experience subjective arousal but may not have reached the full extent of physiological arousal, which includes adequate lubrication. This can result from a lack of sufficient stimulation or a disruption in the arousal process.

Addressing Arousal Non-Concordance with Lubrication

Understanding that arousal non-concordance is a common and normal aspect of human sexuality can help alleviate feelings of inadequacy or embarrassment associated with this phenomenon. There are several strategies that can be employed to address arousal non-concordance with lubrication:

  1. Open communication: Discussing the issue with your partner can help both parties understand that arousal non-concordance is a normal part of human sexuality and not a reflection of either partner's desirability or performance.

  2. Extended foreplay: Engaging in longer periods of foreplay and stimulation can help facilitate the physiological arousal process and increase the likelihood of adequate lubrication.

  3. Use of artificial lubricants: In cases where natural lubrication is insufficient, using artificial lubricants can significantly enhance comfort and pleasure during sexual activity. It's important to remember that using lubricants is a healthy and normal part of sexual activity for many couples.

  4. Addressing underlying factors: If arousal non-concordance is related to factors such as stress, anxiety, or hormonal imbalances, seeking appropriate treatment or interventions can help improve the alignment between subjective and physiological arousal.


Being wet doesn't mean you're ready for penetration! Lubrication is just one stage of arousal, and does not mean you are ready to jump into penetration. It isn't until we are fully engorged that we will feel the most pleasure with penetrative sex- which can take up to 45 minutes for some vulva-havers!

When we are fully engorged, our cervix lifts up within the pelvic bowl, exposing delicious nerves at our P-spot (posterior fornix).


It also increased so much more blood flow to our yoni, which feels much more pleasurable than when we are penetrated un-engorged.


That being some, some people are generally much drier than others, and can become dry with penetration. You know your body and what works for you. If you need to slow down slow down, if you need some lube, there is no shame in that!


As you can see, wetness is a complex phenomenon that deserves time to explore and understand beyond we have been conditioned to think, feel and believe.
