Sex is not supposed to be painful, but a significant number of women experience it. Roughly 10% to 20% of women in the United States report pain during intercourse, and the number climbs much higher in certain life stages like the postpartum period. Pain during sex is common enough that it has a medical name (dyspareunia), yet many women assume it’s normal and never bring it up. It isn’t normal, and in most cases, it’s treatable once the cause is identified.
Where the Pain Occurs Matters
Pain during sex generally falls into two categories based on location: pain at the entrance of the vagina, or deeper pain felt in the pelvis. These two types usually have different causes, which is why paying attention to where you feel it can help narrow down what’s going on.
Entry pain, felt at or near the vaginal opening, is more commonly linked to skin conditions, dryness, infections, or muscle-related issues. Deep pain, felt during full penetration, tends to involve internal structures like the uterus, ovaries, or surrounding tissues. Some women experience both.
Common Causes of Entry Pain
One of the most frequent causes is simply not enough lubrication. This can happen when arousal is insufficient, foreplay is rushed, or hormonal changes reduce the body’s natural moisture. Vaginal dryness is especially common during breastfeeding, perimenopause, and after menopause, when lower estrogen levels cause vaginal tissue to become thinner, less elastic, and more fragile. The vaginal canal can also shorten and tighten over time without estrogen support.
Vulvodynia is chronic pain, burning, or irritation at the vulva with no obvious infection or skin disease causing it. It affects an estimated 10% to 28% of reproductive-aged women over their lifetime. The pain can be constant or triggered only by touch or pressure, including during sex, tampon use, or even prolonged sitting. Diagnosis often involves a simple test where a clinician touches different areas around the vaginal opening with a cotton swab to map exactly where the pain is located.
Vaginismus is an involuntary tightening or spasm of the muscles around the vaginal opening. It can make penetration feel impossible or intensely painful. Some women with vaginismus also have difficulty using tampons or tolerating a pelvic exam. The two conditions can overlap: some women have both vulvodynia and vaginismus, though either can occur on its own.
Yeast infections, bacterial vaginosis, urinary tract infections, and sexually transmitted infections can all cause temporary pain during sex. These are usually accompanied by other symptoms like unusual discharge, itching, or burning with urination, and they resolve with treatment.
What Causes Deep Pain
Endometriosis is one of the most well-known causes of deep pelvic pain during sex. It occurs when tissue similar to the uterine lining grows outside the uterus. Research has found that the strongest predictor of sexual pain in women with endometriosis is the presence of tissue growths behind the cervix. Women with nodules in that area were more than five times as likely to experience pain during intercourse.
Other conditions that cause deep pain include ovarian cysts, uterine fibroids, pelvic inflammatory disease (an infection of the reproductive organs, often from untreated STIs), and adhesions from previous surgeries. These conditions involve inflammation or structural changes that make certain positions or depths of penetration painful.
The Role of Stress, Anxiety, and Past Trauma
Pain during sex isn’t always purely physical. Anxiety, depression, relationship difficulties, concerns about body image, and fear of intimacy can all contribute to low arousal, which in turn leads to less lubrication and more muscle tension. Pelvic floor muscles tend to tighten in response to stress, and that tightness can directly cause or worsen pain.
A history of sexual abuse can also play a role, though not everyone with painful sex has experienced trauma. What’s particularly difficult about the psychological side is that it creates a feedback loop. Initial pain leads to fear of it happening again, which makes it harder to relax, which causes more tension and more pain. Over time, some women begin avoiding sex altogether because they associate it with discomfort. Breaking that cycle usually requires addressing both the physical and emotional components.
Pain After Childbirth
Postpartum pain during sex is extremely common and often underestimated. Up to 83% of women report some form of sexual difficulty in the first three months after delivery. At three months postpartum, about 40% of women who had a vaginal birth report painful sex. By six months, that number drops to roughly 20%.
For most women, things improve steadily over the first year. But the recovery isn’t universal. Research shows that about 38% of women still haven’t returned to their pre-pregnancy level of sexual function at the 12-month mark. Perineal tearing, episiotomy scars, hormonal shifts (especially while breastfeeding), and sleep deprivation all contribute. If pain persists well beyond the early postpartum months, it’s worth investigating rather than waiting it out.
How Painful Sex Is Treated
Treatment depends entirely on the cause, which is why a thorough evaluation is the starting point. A clinician will typically take a detailed history covering the type of pain, when it started, and what makes it better or worse, followed by a physical exam that may include cotton swab testing to locate sensitive areas and checks for infection or skin conditions.
For dryness-related pain, lubricants are often the simplest first step. Not all lubricants are equal, though. The World Health Organization recommends vaginal lubricants with an osmolality below 1,200 mOsm/kg and a pH around 4.5, because products outside those ranges can irritate tissue and make things worse. Many common drugstore brands exceed these thresholds, so reading labels or asking a pharmacist is worthwhile. For menopausal dryness, topical estrogen therapy can restore vaginal tissue over time.
Pelvic floor physical therapy is one of the most effective treatments for muscle-related pain, including vaginismus and some types of vulvodynia. A pelvic floor therapist works with you to identify whether your muscles are too tight, too weak, or uncoordinated, and then uses exercises, manual techniques, and sometimes biofeedback to retrain them. Biofeedback lets you see how your pelvic muscles are responding in real time, which helps you learn to relax them intentionally.
For chronic vulvar pain, treatment is often multidisciplinary. Options range from topical medications (ointments are generally better tolerated than creams, which contain more preservatives that can cause burning) to oral medications that target nerve-related pain. Nerve stimulation therapy is another option. In cases where pain is localized to the vaginal entrance and nothing else has worked, a minor surgical procedure to remove the affected tissue may be considered, but only after other treatments have been tried.
When emotional factors are involved, working with a sexual counselor or psychologist alongside physical treatment tends to produce better results than addressing either piece alone. Cognitive behavioral therapy can be particularly helpful for breaking the pain-fear-tension cycle.
What “Normal” Actually Looks Like
Some mild discomfort the very first time you have penetrative sex is common, though even that isn’t inevitable. Beyond that initial experience, sex should not hurt. Occasional mild discomfort in a new position or at a particular point in your menstrual cycle can happen, but recurring pain, pain that makes you tense up in anticipation, or pain that limits what you’re willing to do sexually all signal that something treatable is going on. The cause might be straightforward, like insufficient lubrication or a minor infection, or it might take more investigation. Either way, it’s a solvable problem, not something to push through.
