Pain During Sex: What Causes It, How to Fix It, and When to Get Seen

Pain during sex affects roughly 10% to 20% of U.S. women. It is common, but it is not normal and not something to quietly tolerate. The pain almost always traces to a specific cause, such as low estrogen, pelvic floor muscle spasm, vulvar pain, or a pelvic condition, and most of those causes are treatable.

TL;DR: Key takeaways

• Where it hurts matters more than how it hurts: entry pain and deep pain point to different causes and different treatments.
• Start with friction and arousal (lubricant, moisturizer, more time), then change position and depth control, then pelvic floor physical therapy.
• Give each self-care step a real trial of 2 to 4 weeks. If pain persists past that, book an appointment instead of trying harder.
• Menopause-related pain and postpartum pain are different problems with different fixes. Six weeks postpartum is a floor, not a finish line.
• Sudden severe one-sided pelvic pain, heavy bleeding, or pelvic pain with fever and foul-smelling discharge needs same-day care.

Pain during sex is common, but it is not normal, and not your job to tolerate

Pain during sex, clinically called dyspareunia, affects approximately 10% to 20% of women in the United States, according to a 2021 American Family Physician review. It is almost never "just part of being a woman." In most cases it traces to an identifiable cause: low estrogen, pelvic floor muscle spasm, vulvar pain, or a pelvic condition. Most of those causes respond to treatment.

Yet only about 25% of women with painful sex ever seek care for it, usually out of embarrassment or a belief that the pain is a normal part of aging. That silence, not the pain itself, is what turns a treatable problem into a decade-long one.

So read this as a triage and self-care sequence, not a diagnosis. A pelvic exam is what names the cause. Nothing on this page can do that.

Where it hurts narrows the cause faster than any list of symptoms

Clinicians sort dyspareunia by location, not severity: superficial (entry) pain, positional pain, and deep pain. That split does most of the diagnostic work. Entry pain points toward vaginal dryness, vaginismus (involuntary tightening of the pelvic floor muscles at penetration), or vulvodynia, defined as chronic genital pain lasting three months or longer. Deep pain points elsewhere: endometriosis, pelvic adhesions, a retroverted uterus, fibroids, or an ovarian mass.

Two questions you can answer tonight. Does it hurt at first contact or entry, or only with deep thrust and in certain positions? And is it every single time, or does it track with position and where you are in your cycle?

Prevalence estimates vary wildly depending on how the question is asked. U.S. figures range from about 7% to 46% of women, with global estimates of 8% to 56%, and lifetime vulvodynia prevalence sits somewhere between 10% and 28%. The 10% to 20% number is the conservative, most-cited one. Treat "roughly 1 in 5" as a reasonable shorthand, not a settled fact.

Whichever branch your answers land on, the destination is the same: an exam. Write down location, timing, and triggers for two to four weeks and bring the note with you. A health companion app like August AI can help you log pain location, timing, and triggers between now and the appointment, which is far more useful to a clinician than trying to reconstruct it in the room. Patterns you might not connect on your own, like weight gain around ovulation or night sweats in the days before your period, belong in that same log.

Step 1: fix friction and arousal before you blame anything else

Vaginal dryness is the most commonly cited contributor across clinical sources, and it is driven mainly by two things: low estrogen (menopause, breastfeeding) and simply not enough arousal time. It is also the cheapest thing to fix, which is exactly why it gets skipped or done badly.

Know the difference between the two products. A lubricant is used at the time, water-based or silicone-based, and reapplied more generously than you think is necessary. A vaginal moisturizer is different: you use it two to three times a week whether or not you are having sex, to change baseline tissue comfort rather than one encounter.

Then extend arousal time deliberately, not apologetically. Pain that disappears completely once lubrication is genuinely adequate is a friction problem, not a disease.

Give this two to four weeks of consistent use before you decide it failed. That threshold is the part no other page states, and it matters in both directions: it stops you abandoning a working fix after one try, and it stops you spending a year on lubricant when the cause is muscular.

Step 2: change the position, then give your partner an actual script

Positional painful intercourse is its own pattern, named alongside entry and deep pain in Cleveland Clinic's breakdown of pain locations, and it responds to depth and angle control rather than to medication. The mechanical change is specific: positions where the receiving partner controls depth and pace (on top, or side-lying), shallower penetration, and slower entry.

"Communicate more" is not advice. Here are words that work: "I want to keep going, but I need you to stop moving and let me set the depth." Agree on a one-word stop signal beforehand, something unmistakable, so you are not negotiating mid-moment.

Then build in a checkpoint. Pause at an agreed point, say the pain number out loud on a 0 to 10 scale, and stop entirely at anything above a number you both set in advance. Never push through sharp pain. Non-penetrative intimacy is a legitimate holding pattern while the cause is being treated, not a consolation prize.

Here is what most pages will not tell you: repeatedly pushing through pain teaches your pelvic floor to brace in anticipation. That protective reflex then becomes its own source of pain, independent of whatever started it. It is also what Step 3 exists to undo.

Step 3: pelvic floor physical therapy is first-line care, not a last resort

Pelvic floor physical therapy is a first-line, cause-matched treatment, particularly for vaginismus and muscle-guarding pain, and you do not have to earn it by failing everything else first. A session is less intimidating than it sounds: assessment, breathing and down-training to teach the muscles to release rather than grip, and internal manual release of trigger points.

Dilators are where most people are handed a box and no instructions. Start with the smallest size and plenty of lubricant. Ten to fifteen minutes, three to five days a week. Stay at one size until insertion is consistently painless, then size up. Progress is measured in weeks to months, and going back down a size on a bad week is normal, not failure. A health companion app like August AI can help you track size and pain scores week over week, which is how you see improvement that is too gradual to feel.

Your clinician confirms the cause with a detailed pain history, visual inspection and cotton-swab testing of the vulva, a single-digit vaginal exam of the pelvic floor muscles, and a bimanual exam for pelvic masses or an abnormal uterine position. Other cause-matched options worth asking about include cognitive behavioral therapy, topical vaginal estrogen, onabotulinumtoxinA injections, and modified vestibulectomy for refractory vestibular pain.

The catch: treatment response typically takes several months, follow-up to 24 months is recommended, and complete resolution is not guaranteed. Anyone promising a fast fix is selling something.

Menopause pain and postpartum pain are not the same problem

Painful sex after menopause is usually genitourinary syndrome of menopause, and it is close to universal in its reach: 40% to 84% of affected postmenopausal women report painful sex. The treatment is hormonal rather than mechanical. Topical vaginal estrogen is the mainstay, and ospemifene is an FDA-approved oral medication for menopause-related pain with sex. Ask your clinician which fits you.

Postpartum pain is a different animal. About 35% of women experience it during the first year after childbirth. The six-week clearance is a floor, not a finish line. Pain still present after it deserves re-examination for scar tissue or perineal pain, breastfeeding-related low estrogen, or pelvic floor dysfunction. Do not wait out a second year hoping it resolves. Breastfeeding dryness is hormonal and usually temporary, but temporary is not the same as untreatable.

If you want a starting point for the hormonal side of this, August's $39 online urgent care visit connects you with a US-licensed clinician who can evaluate your symptoms and decide whether a prescription is appropriate. Be clear about its limits: a telehealth visit cannot perform the pelvic, cotton-swab, or bimanual exam that deep or unexplained pain requires. It is a front door or a follow-up, not a replacement for being examined.

Some symptoms mean stop self-treating and get seen

Call 911 or go to an emergency room now if:

• Pelvic pain comes on suddenly or severely on one side (possible ovarian torsion or cyst rupture).
• Bleeding during or after sex is heavy, persistent, or unexplained.
• You have pelvic or low back pain with fever and chills plus foul-smelling discharge (possible pelvic inflammatory disease, which needs same-day assessment).

Book a visit within the next week if:

• The pain is new or clearly getting worse, or it happens at every attempt.
• Pain persists beyond a two to four week trial of lubricant, extended arousal, and position changes.
• You have bleeding during or after intercourse, new genital sores or lesions, abnormal discharge without fever, or irregular or absent periods alongside the pain.
• Postpartum pain is still present past six weeks.

Talk to a clinician before you start if:

• You are considering dilators or any vaginal estrogen and have a history of sexual trauma or assault, a suspected infection, unexplained bleeding, current pregnancy, are under six weeks postpartum, or have a history of estrogen-sensitive cancer.

If you genuinely cannot tell which tier you are in, the free August AI Symptom Checker can help you sort the urgency before you decide what to book. It does not diagnose, and it does not replace the pelvic exam that distinguishes these causes. No article, app, or checklist can.

The bottom line: work the steps, but escalate on a schedule

Work the sequence in order: friction and arousal, then position plus a script, then pelvic floor therapy and dilators, then cause-matched medical treatment. Two to four weeks of honest self-care without improvement, or any red flag at all, means book the appointment. Pain during sex is common, treatable, and badly under-reported. Being the person who brings it up is the step that changes the outcome.
