Painful sex has dozens of possible causes, ranging from treatable infections and hormonal shifts to chronic conditions like endometriosis and nerve-related pain syndromes. The medical term for it is dyspareunia, and it affects people of all genders, though the research and clinical attention have focused overwhelmingly on women. The cause is rarely “all in your head,” even when a doctor cannot immediately find one, and most causes respond well to targeted treatment once correctly identified.
Where the Pain Shows Up Changes What It Means
One of the most useful pieces of information you can bring to a doctor is where, exactly, the pain occurs. Clinicians generally divide sexual pain into two categories: superficial (felt at the vaginal opening during initial penetration) and deep (felt internally during deeper penetration). The two categories often point to different underlying problems, though they overlap more than you might expect. In one study of women with a superficial pain condition called provoked vestibulodynia, close to half also experienced deep pain at the same time.1The Journal of Sexual Medicine. Concurrent Deep–Superficial Dyspareunia: Prevalence, Associations, and Outcomes in a Multidisciplinary Vulvodynia Program That overlap complicates diagnosis and helps explain why so many people cycle through multiple providers before getting answers.
Superficial pain is more commonly linked to vulvar skin conditions, vaginal dryness, infections, pelvic floor muscle tightness, or nerve hypersensitivity at the vaginal entrance. Deep pain tends to implicate conditions further inside the pelvis: endometriosis, ovarian cysts, pelvic inflammatory disease, or bladder disorders. But the two can feed each other. Chronic superficial pain can cause you to involuntarily clench pelvic muscles, which then produces a deeper ache, and deep conditions like endometriosis frequently co-exist with pelvic floor dysfunction that also causes superficial tenderness.2PubMed Central.

Vestibulodynia and Vulvar Pain Syndromes
Provoked vestibulodynia is one of the most common causes of superficial pain during sex in premenopausal women, and also one of the most under-recognized. The hallmark is sharp, burning pain at the vaginal entrance triggered by touch or pressure, whether from intercourse, tampon insertion, or even tight clothing. The vestibule, the tissue just inside the vaginal opening, becomes exquisitely sensitive.
Researchers have identified several factors that contribute to this sensitivity. Inflammation, recurrent vaginal infections, hormonal changes, pelvic floor muscle dysfunction, and genetic predisposition all appear to play a role.3PubMed Central. Recent advances in understanding provoked vestibulodynia In some women, biopsies of the vestibular tissue show a measurable increase in the density of nerve fibers, a subtype now called neuroproliferative vestibulodynia.4The Journal of Sexual Medicine. Characterizing the innervation of the vulvar vestibule and the immunohistochemical features of neuroproliferative vestibulodynia In plain terms, the tissue has grown extra pain-sensing nerves, which makes stimuli that should feel neutral register as painful. The condition is not fully understood, but the nerve proliferation finding gives clinicians something concrete to work with when deciding on treatment.
Endometriosis and Deep Pelvic Pain
Endometriosis affects roughly one in ten women of reproductive age, and about half of those with the condition experience deep pain during sex.5Sexual Medicine Reviews. Deep Dyspareunia in Endometriosis: A Proposed Framework Based on Pain Mechanisms and Genito-Pelvic Pain Penetration Disorder The pain tends to worsen with deeper penetration and certain positions, and it can linger for hours afterward. Endometriotic lesions grow on pelvic organs, ligaments, and the tissue lining the pelvis, creating inflammation and sometimes scar tissue that makes the structures less flexible and more tender.
What makes this harder to treat is that the sexual pain in endometriosis is not always caused by the lesions alone. Research has found that bladder and pelvic floor tenderness independently contribute to pain severity in both early and advanced stages of the disease. Women with early-stage endometriosis who also had painful bladder syndrome or pelvic floor tenderness reported roughly twice the severity of deep pain compared to those without these additional findings.6The Journal of Sexual Medicine. Deep Dyspareunia in Endometriosis: Role of the Bladder and Pelvic Floor This means that surgically removing endometriosis lesions or suppressing them with hormones may not fully resolve sexual pain if the bladder or muscle components are left unaddressed. Placebo-controlled trials have yet to demonstrate a clear benefit of traditional endometriosis treatments for deep dyspareunia specifically, likely because of this multifactorial nature.5Sexual Medicine Reviews. Deep Dyspareunia in Endometriosis: A Proposed Framework Based on Pain Mechanisms and Genito-Pelvic Pain Penetration Disorder
Hormonal Shifts That Change the Tissue
Estrogen keeps vaginal tissue thick, elastic, and lubricated. When estrogen drops, the tissue thins, dries out, and becomes more easily irritated. This happens most dramatically at menopause, but it also occurs during breastfeeding, after surgical removal of the ovaries, and sometimes with certain medications.
At menopause, the resulting changes are collectively called genitourinary syndrome of menopause, which includes vaginal dryness, itching, irritation, reduced lubrication, and pain during sex.7PubMed. Identifying and treating sexual dysfunction in postmenopausal women: the role of estrogen The syndrome can also involve changes to the urethra and bladder, contributing to urinary symptoms alongside sexual discomfort.8Clinical Obstetrics and Gynecology. Managing Menopause by Combining Evidence With Clinical Judgment – Section: Genitourinary Syndrome of Menopause Unlike hot flashes, which often improve on their own over time, vaginal atrophy tends to get worse without treatment.
Breastfeeding creates a similar hormonal environment. High prolactin levels suppress estrogen and androgen production, leading to vulvovaginal atrophy, dryness, and pain during sex even in younger women.9PubMed Central. Sexual function in breastfeeding women: a systematic review Researchers have proposed calling this “genitourinary syndrome of lactation” to highlight that it is a recognized physiological phenomenon, not a personal failing.10Sexual Medicine Reviews. Genitourinary syndrome of lactation: a new perspective on postpartum and lactation-related genitourinary symptoms The good news is that it typically resolves after weaning, though lubricants and low-dose vaginal estrogen can help in the meantime.
Oral contraceptives add another wrinkle. Combined hormonal birth control raises levels of a protein called sex hormone-binding globulin, which binds up free testosterone. In one study, women who had used oral contraceptives had binding-globulin levels roughly four times higher than women who had never used them, and those levels remained elevated even after stopping the pill.11PubMed Central. Impact of oral contraceptives on sex hormone-binding globulin and androgen levels: a retrospective study in women with sexual dysfunction Lower free testosterone can contribute to reduced desire and changes in vulvar tissue sensitivity. This does not mean birth control always causes pain, but it is a factor worth discussing with a provider if pain appeared or worsened after starting hormonal contraception.
Pelvic Floor Muscle Problems
The pelvic floor muscles form a sling at the base of the pelvis and are involved in virtually every act of penetration. When these muscles are chronically tight, or hypertonic, they can be a primary source of pain during sex on their own, or they can amplify pain caused by something else. A tight pelvic floor can be the primary symptom generator, or it can act as a perpetuating factor in ongoing pain. If it goes unidentified and untreated, symptoms often persist or return even after other treatments succeed.12Obstetrics and Gynecology Clinics of North America. Pelvic Floor Hypertonic Disorders
You do not need to have a diagnosed condition for your pelvic floor to be part of the problem. Stress, anxiety, prior painful experiences, even habitual postures can lead to chronic clenching that you may not be aware of. Physical therapists who specialize in pelvic health can assess muscle tone, identify trigger points, and guide relaxation techniques. This is one of the most consistently helpful interventions across multiple causes of sexual pain.
Infections, Skin Conditions, and Inflammation
Vaginal and vulvar infections are among the more straightforward causes of painful sex, though they are not always as simple as they seem. Common culprits include yeast infections, bacterial vaginosis, and sexually transmitted infections. A large U.S. clinical study found that close to one in five women presenting with vaginitis symptoms also had at least one sexually transmitted infection, and the rate was even higher among women with bacterial vaginosis.13PubMed Central. Vaginitis and risk of sexually transmitted infections: results of a multi-center U.S. clinical study using STI nucleic acid amplification testing Chlamydia in particular has been linked to pain during intercourse and reduced sexual satisfaction in young women.14The Journal of Sexual Medicine. Genital Chlamydia trachomatis Infection is Related to Poor Sexual Quality of Life in Young Sexually Active Women The overlap between vaginitis and STIs means that testing for infections should be thorough rather than stopping at the first positive result.
Skin conditions on the vulva are an underappreciated cause of chronic pain. Lichen sclerosus, lichen planus, contact dermatitis, and vulvar psoriasis can all produce burning, itching, and pain that makes sex difficult or impossible. These conditions can cause chronic pain and have a profound effect on sexual comfort.15Sexual Medicine Reviews. Vulvar Dermatoses: A Primer for the Sexual Medicine Clinician Because the vulva is not an area most people examine closely, and because the symptoms can mimic infections, these dermatological conditions are often misdiagnosed for months or years. A biopsy or referral to a dermatologist with vulvar expertise can speed up the process.
After Childbirth and Pelvic Surgery
Painful sex after vaginal delivery is extremely common and not always temporary. In a large registry-based study, about 30% of women reported mild or moderate pain during sex after a spontaneous perineal tear, with a similar rate after episiotomy.16PubMed Central. Self-reported dyspareunia and outcome satisfaction after spontaneous second-degree tear compared to episiotomy: A register-based cohort study Episiotomy carried a notably higher risk of scar tenderness compared to spontaneous tearing.17The Journal of Sexual Medicine. Postpartum dyspareunia: clinical evaluation, causes, and treatment outcomes
In some cases, the scar itself becomes the problem. Scar tissue can develop abnormal nerve sensitivity, a phenomenon called allodynia, where normal touch registers as painful. One documented case involved a woman whose episiotomy scar caused superficial pain severe enough to affect her relationships for years, and the pain only resolved after surgical excision of the scar.18Anaesthesia, Pain & Intensive Care. Allodynia at episiotomy scar as an unusual cause for dyspareunia: a case report That is an extreme outcome, but it illustrates why persistent postpartum pain deserves evaluation rather than the common reassurance to “just give it time.”
Pain During Sex in Men
Sexual pain is not exclusively a problem for people with vaginas. Men experience it too, though the research is far thinner. Ejaculatory pain is a common feature of chronic prostatitis and chronic pelvic pain syndrome, a frustrating condition that involves persistent pelvic discomfort without a clear infectious cause.19PubMed. The male sexual pain syndromes Pain can also occur with erection, during thrusting, or at the tip of the penis, and causes range from tight foreskin (phimosis) and Peyronie’s disease to infections and referred pain from the lower back or hips. Men tend to report sexual pain less often to clinicians, partly because of stigma and partly because providers do not always ask. If sex hurts, the same principle applies regardless of gender: the pain has a cause, and it is worth investigating.
Treatments That Help
Treatment depends entirely on the cause, which is why accurate diagnosis matters so much. But several approaches have strong evidence behind them and apply across multiple conditions.
Pelvic floor physical therapy is among the most broadly effective treatments. In a retrospective analysis of women with dyspareunia treated using a movement-based dilator protocol alongside pelvic floor therapy, average pain scores dropped from about 8 out of 10 to about 1 out of 10 over an average of roughly four sessions, and more than half reported complete resolution of pain.20Sexual Medicine. Low Dose, High Frequency Movement Based Dilator Therapy for Dyspareunia: Retrospective Analysis of 26 Cases For women with vaginismus, which involves involuntary muscle spasm that prevents penetration, dilator therapy combined with biofeedback has shown benefit, with the combination outperforming dilators alone.21PubMed. Effectiveness of Biofeedback with Dilator Therapy for Sexual Function in Women with Primary Vaginismus: Randomized Controlled Trial Study
Cognitive behavioral therapy has shown results that match physical therapy for pain reduction in vestibulodynia. In a pilot trial, both CBT and physical therapy led to clinically meaningful pain decreases, with 70% and 80% of participants respectively achieving at least a 30% reduction in pain. CBT had the additional advantage of improving overall sexual functioning, not just pain.22PubMed. Effectiveness of Cognitive-Behavioral Therapy and Physical Therapy for Provoked Vestibulodynia: A Randomized Pilot Study Physical therapists treating sexual pain increasingly incorporate psychological strategies like pain education, mindfulness-based stress reduction, and guided imagery alongside manual techniques, reflecting the understanding that pain is not purely a tissue problem.23Sexual Medicine Reviews. Physical Therapy in the Treatment of Central Pain Mechanisms for Female Sexual Pain
Medication options exist but are more targeted. Gabapentin, a nerve-pain drug, improved overall sexual function in women with vulvodynia in a randomized placebo-controlled trial, including improvements in desire, arousal, and satisfaction. The benefit was most pronounced in women who also had significant pelvic muscle pain.24PubMed Central. Effect of gabapentin on sexual function in vulvodynia: a randomized, placebo-controlled trial For hormone-related dryness and atrophy, low-dose vaginal estrogen is the standard first-line treatment. For refractory pelvic floor muscle pain, botulinum toxin injections into the pelvic floor have shown a meaningful improvement in pain scores at six-month follow-up, along with improvements in quality of life.25PubMed Central.

How Partners Affect the Experience
Sexual pain does not happen in a vacuum. The way a partner responds to pain during sex measurably affects both the pain itself and the broader sexual and relationship satisfaction of both people. Research on couples where one partner has provoked vestibulodynia found that when partners communicated more openly about sex, women reported lower pain and greater sexual satisfaction.26PubMed. Talking About Sex When Sex Is Painful: Dyadic Sexual Communication Is Associated With Women’s Pain, and Couples’ Sexual and Psychological Outcomes in Provoked Vestibulodynia
The type of partner response matters in nuanced ways. On days when women perceived their partner as more encouraging and facilitative than usual, both pain and satisfaction improved. But when partners became overly solicitous, focusing excessively on the pain, asking repeatedly if it hurt, treating the person as fragile, both partners actually reported lower sexual satisfaction.27The Journal of Sexual Medicine. Daily Associations Between Partner Responses and Sexual and Relationship Satisfaction in Couples Coping with Provoked Vestibulodynia The distinction is subtle but important: supportive acknowledgment helps, while anxious hovering does not. Couples-based therapy that includes sexual communication skills is increasingly recognized as a useful component of treatment.
Why Getting Diagnosed Takes So Long
One of the most frustrating aspects of sexual pain is the diagnostic journey itself. In a mixed-methods study exploring how women with dyspareunia navigate the healthcare system, half of the participants had never undergone a formal diagnostic process for their pain. Qualitative findings revealed frequent dismissive responses from healthcare professionals and limited access to appropriate management.28PubMed Central. Exploring the Diagnostic and Therapeutic Pathways of Women with Dyspareunia: A Mixed-Methods Study Common self-management strategies included changing positions and using lubricants, and half of the participants did not know that pelvic floor physiotherapy was even an option.
The most frequently given diagnoses were hormonal disorders and recurrent genital infections, which, while sometimes accurate, can become catch-all labels that prevent deeper investigation. If you have been told your pain is hormonal but hormonal treatment has not helped, or if you have been treated for repeated infections without resolution, it is reasonable to push for further evaluation, ideally with a provider who specializes in vulvar pain, pelvic floor disorders, or sexual medicine. Multidisciplinary programs that combine gynecology, physical therapy, and psychological support tend to produce the best outcomes for complex cases.
Pain After Gender-Affirming Surgery
Sexual pain can also arise after gender-affirming surgical procedures. A scoping review found that pain was reported across body regions following both feminizing and masculinizing surgeries. After vaginoplasty, vaginal stenosis, or narrowing of the surgically created vaginal canal, was the most common complication, and patients were most frequently referred to physical therapists for stenosis or dyspareunia.29Physical Therapy. Pain and Dysfunction Reported After Gender-Affirming Surgery: A Scoping Review Consistent dilation, pelvic floor therapy, and proper lubrication are key parts of post-surgical care. Transgender and nonbinary individuals face additional barriers to sexual pain care, including provider unfamiliarity with their anatomy and a shortage of pelvic floor therapists trained in post-surgical rehabilitation for these procedures. Seeking out a provider with specific experience in gender-affirming aftercare can make a meaningful difference.
