Pain during sex is common, affecting an estimated 8% to 35% of women at some point in their lives, and it happens to men too. It’s not something you should push through or dismiss as normal. The causes range from simple fixable issues like dryness to more complex conditions involving muscles, nerves, or deeper pelvic structures. Understanding where and when the pain happens is the fastest way to narrow down what’s going on.
Where the Pain Occurs Matters
Sexual pain generally falls into two categories based on location: entry pain and deep pain. They point to different causes and have different solutions.
Entry pain, sometimes called superficial pain, is felt right at the vaginal opening during initial penetration. Common causes include dryness, hormonal changes, chronic irritation, infections, or injury to the tissue around the opening. This is the more frequent type, and it’s often the easier one to address.
Deep pain happens with full penetration and may feel worse in certain positions. It tends to involve structures further inside the pelvis: the bladder, bowel, pelvic floor muscles, or conditions like endometriosis. Deep pain that consistently occurs in specific positions is a useful clue to share with a healthcare provider.
Vaginal Dryness and Hormonal Changes
Insufficient lubrication is one of the most common and straightforward reasons sex hurts. Without enough moisture, friction against vaginal tissue causes burning, stinging, or a raw feeling. This can happen for many reasons: not enough arousal time, certain medications (antihistamines and some antidepressants are frequent culprits), dehydration, or hormonal shifts.
Hormonal changes deserve special attention because they affect so many people. During perimenopause and menopause, the body shifts from producing a potent form of estrogen to a weaker one. This leads to thinner, less elastic vaginal tissue and reduced natural lubrication. The result is a condition now called genitourinary syndrome of menopause, and it doesn’t resolve on its own. Breastfeeding, certain birth control methods, and some cancer treatments can trigger similar hormonal drops at any age.
A lubricant can make an immediate difference. Water-based lubricants are the gentlest option and feel most similar to natural lubrication. Silicone-based versions last longer and work well when extra staying power is needed. Avoid products with glycerin or parabens if you’re prone to yeast infections or have sensitive skin, and skip anything labeled “warming” or “tingling,” as these often cause irritation. Household products like petroleum jelly, baby oil, cooking oils, and lotions should never be used as substitutes. They can disrupt the vagina’s natural pH (which sits between 3.8 and 4.5) and increase infection risk. If you’re trying a new lubricant, test a small amount on a less sensitive patch of skin first to check for any reaction.
Infections That Cause Pain
Yeast infections, bacterial vaginosis, chlamydia, and gonorrhea can all make sex painful. The inflammation and irritation they cause makes tissue more sensitive to friction and pressure. You might also notice unusual discharge, odor, itching, or burning outside of sex. These infections are treatable with antibiotics or antifungal medication, and the pain typically resolves once the infection clears. Recurring yeast infections, in particular, can leave the tissue chronically irritated, so addressing the cycle matters.
Involuntary Muscle Tightening
Vaginismus is a condition where the muscles around the vaginal opening tense or contract involuntarily when penetration is anticipated or attempted. The tightening happens automatically, not by choice, and it can make penetration extremely painful or even impossible. Some people experience it with any form of insertion, including tampons and pelvic exams, while others notice it only during sex.
The muscle response can develop for many reasons. Sometimes it starts after a painful experience (an infection, a rough exam, childbirth) and the body essentially learns to brace against penetration. Anxiety and past trauma can also play a role. Clinicians now group vaginismus together with painful intercourse under a single diagnosis called genito-pelvic pain/penetration disorder, recognizing that the muscle guarding and the pain often feed into each other.
Chronic Vulvar and Nerve Pain
Some people experience a burning or stinging pain at the vaginal entrance that doesn’t have an obvious cause like an infection or dryness. This is called vestibulodynia, the most common form of chronic vulvar pain. In provoked vestibulodynia, the pain shows up specifically when pressure is applied to the vaginal opening, whether from sex, a tampon, a pelvic exam, or even prolonged sitting or tight clothing.
The underlying issue appears to involve the nerves in the area. Some people have a higher density of nerve endings in the vulvar tissue, and those nerves become hypersensitive. Light touch that shouldn’t hurt registers as painful, and sensations that would normally be mildly uncomfortable become intensely so. Chronic yeast infections and sensitivities to irritants in scented soaps, detergents, or pantyliners can contribute to or worsen the condition. Vestibulodynia is diagnosed when the pain has lasted at least three months and other causes have been ruled out.
Endometriosis and Deep Pelvic Conditions
Deep pain during sex, particularly with thrusting, often points to something happening in the pelvic cavity itself. Endometriosis is one of the most common causes. The condition creates inflammation and hard nodules around pelvic organs, and the physical impact of intercourse presses against or jostles these inflamed areas. The pain may be sharp and positional, meaning it flares in certain angles but not others.
Pelvic inflammatory disease, bladder conditions, bowel disorders, and pelvic congestion syndrome (essentially varicose veins in the pelvis) can produce similar deep pain. If deep pain during sex comes with other symptoms like painful periods, bloating, urinary urgency, or pain with bowel movements, those patterns help identify the underlying condition.
Anxiety, Trauma, and the Pain Cycle
Pain during sex is never purely “in your head,” but psychological factors can powerfully shape the body’s physical response. Past sexual trauma can leave the nervous system hypervigilant. Touch during intimacy can trigger flashbacks or cause the brain to interpret safe contact as threatening, leading to dissociation, muscle guarding, or a spike in pain sensitivity. The body reacts before the conscious mind has time to process what’s happening.
Even without a trauma history, anxiety about pain creates a self-reinforcing loop. If sex hurt last time, you may unconsciously tense your muscles the next time, which increases friction and pressure, which causes more pain, which builds more anxiety. Breaking this cycle often requires addressing both the physical and emotional sides at once.
Pain During Sex for Men
Men experience painful sex too, though it’s discussed far less often. Pain during or after ejaculation can stem from prostate inflammation or infection. A tight foreskin that doesn’t retract comfortably (phimosis) causes pain with penetration. Peyronie’s disease, where scar tissue creates a curve in the penis, can make erections and intercourse painful. Skin conditions on the penis, testicular pain from conditions like varicoceles, and bladder infections are other possible sources. As with vaginal pain, the location and timing of the discomfort are the most important clues.
How Pelvic Floor Therapy Helps
Pelvic floor physical therapy is one of the most effective treatments for many forms of sexual pain, particularly when muscle tension, vaginismus, or nerve sensitivity is involved. A pelvic floor therapist works directly with the muscles of the pelvic floor using manual techniques, biofeedback (a sensor that shows you how your muscles are contracting so you can learn to control them), and graduated exercises or dilators to retrain the muscles over time.
The results are encouraging. Studies show that 59% to 80% of women report improvement in pelvic pain after manual therapy. For pain specifically during sex, about 45% of patients in one study reported improvement after at least 12 sessions. A 2019 clinical trial found that women who received targeted pelvic floor therapy showed significant improvement in pain, sexual function, and overall quality of life compared to those who received general physical therapy. Improvement in pain scores has been documented after as few as five weeks of twice-weekly sessions, with benefits lasting months after treatment ended.
Beyond physical therapy, treatment depends entirely on the cause. Hormonal therapies can restore vaginal tissue in menopause-related pain. Infections clear with the right medication. Endometriosis may require hormonal management or surgery. For pain tied to trauma or anxiety, therapy with a provider experienced in sexual health can address the nervous system patterns that keep the cycle going. Many people benefit from a combination of approaches, and finding the right mix starts with identifying the specific type and location of pain.
