Sex is supposed to feel good. So when it stings, burns, aches, or feels like someone is knocking on a door that is very much locked, it's easy to assume something is wrong with you. Spoiler: nothing is wrong with you. Pain is information, not a character flaw.
Painful sex is far more common than anyone admits at brunch, and it has real, identifiable causes. In this guide we walk through the most common painful sex causes, what actually helps (from clinicians and from your nightstand), and how to keep pleasure on the menu while you figure it out.
Fair warning: we'll name body parts plainly. Vulvas, vaginas, penises, anuses, pelvic floors. If you have one, it deserves a pain-free good time.
How Common Is Painful Sex, Really?
Very. A large British national survey (Natsal-3) found that about 7.5% of sexually active women reported painful sex lasting three months or more in the past year. Reports peaked in two age groups: 16 to 24 and 55 to 64. That's not a niche problem. That's a whole bus of people quietly gritting their teeth.
The same study found fewer than half of those with the most severe, distressing pain had sought help in the past year. And when people do ask, the authors note, they often get dismissed or brushed off. If that's happened to you, it wasn't your imagination, and it wasn't your fault.
Two gaps worth naming: that survey only looked at women, and most painful-sex research centers cis women having penis-in-vagina sex. But pain doesn't check your ID. Trans and nonbinary people, people having anal sex, and penis owners experience it too, and we'll cover all of you below.
Painful Sex Causes: The Usual Suspects
Clinicians often sort pain by where it shows up, because location is a big clue. Mayo Clinic breaks it down roughly like this:
Pain at the entrance
- Dryness. Low estrogen (after menopause, while chestfeeding or breastfeeding, or on some medications) can thin and dry the tissue.
- Medications. Some antidepressants and blood pressure meds can dampen desire or arousal, which can mean less natural lubrication.
- Infections and skin conditions. Genital or urinary tract infections, plus skin conditions like eczema, can all make the vulva cranky.
- Vaginismus. Involuntary tightening of the muscles around the vaginal opening, which can make penetration painful or impossible.
- Injury or irritation. From childbirth, surgery, or an over-enthusiastic night without enough prep.
Deep pain
If it hurts more with deep thrusting, the culprit may live further in: endometriosis, pelvic inflammatory disease, fibroids, ovarian cysts, pelvic floor dysfunction, scarring from surgery, or effects of cancer treatment. Some positions simply hit sensitive structures, too.
The mind-body piece
Stress and anxiety can clench your pelvic floor like a fist. Fear of pain can make it harder to relax, which causes more pain, which causes more fear. It's a loop, not a weakness. A history of sexual trauma can also play a role; if that's part of your story, you deserve trauma-informed care, and you can reach RAINN any time at 800-656-4673.
Is It Just Dryness? (Often, Partly, Yes)
In the Natsal-3 data, an uncomfortably dry vagina was the single strongest factor linked to painful sex. About 45% of women with painful sex reported dryness, compared with about 10% of those without pain. Feeling anxious during sex and not enjoying it were also strongly linked.
That doesn't mean lube fixes everything. But it does mean lube is the cheapest, easiest first experiment you can run tonight. Arousal is a process, not a light switch, and plenty of bodies need more warm-up time (and more slip) than the movies suggest.

Menopause, HRT & the Estrogen Factor
When estrogen drops, vaginal and vulvar tissue can become thinner, drier, and more fragile. Doctors call this genitourinary syndrome of menopause (GSM). A 2023 review estimated it affects roughly 40 to 54% of postmenopausal women, yet most never get diagnosed.
That review describes water-based lubricants and vaginal moisturizers as first-line options, with low-dose vaginal estrogen as the most effective treatment for moderate to severe symptoms. A clinician can tell you whether that's a good fit for you, especially if you've had a hormone-sensitive cancer.
For trans men and transmasculine folks on testosterone, there's a parallel story. In a 2023 study of 1,219 transgender and gender-diverse people assigned female at birth, about 65% reported some genital pain or discomfort during sex in the past month, and current testosterone use was linked to more vaginal or frontal-opening pain. If you're on T and penetration suddenly hurts, that's a known, treatable effect, not a sign you're doing gender wrong. Ask a trans-competent provider about options, and go heavy on the lube. We have more ideas in our guide to gender-affirming sex when dysphoria shows up.

Pain Isn't Just a Vagina Thing
Anal sex pain
Let's bust a myth: anal sex is not supposed to hurt. A 2005 study of 404 men who have sex with men found 14% experienced frequent, severe pain during receptive anal sex (sometimes called anodyspareunia). Most said psychological factors like tension and anxiety were the main contributors, and the authors argued their findings challenge the idea that pain is just "part of" receptive anal sex. The basics apply to every butt owner: go slow, use plenty of lube (the anus makes none of its own), start small, and stop if it hurts.
Pain for penis owners
Painful erections, a new bend, or a firm lump under the skin can be signs of Peyronie's disease, a buildup of scar tissue inside the penis. Mayo Clinic notes it's often linked to repeated minor injury, and that early treatment gives the best chance of improvement. Pain with ejaculation, burning, or sores are also worth a prompt checkup.
Treatments That Actually Help
The good news: painful sex is very treatable, and you usually have more options than "just relax" (please never take that advice from anyone again).
Pelvic floor physical therapy
Pelvic floor PTs are the unsung heroes of the sex world. In a 2019 randomized trial of 64 women with painful sex, those who got 10 weeks of pelvic floor rehab (manual therapy, biofeedback, education, and home exercises) reported much less pain and better sexual function than a waitlist group, with benefits holding at a three-month follow-up. It was a small study, but it fits what clinicians see.
Medical treatment
Depending on the cause, that might mean treating an infection, adjusting a medication that dries you out, managing endometriosis, or using vaginal estrogen or other prescription options. Don't stop or change meds on your own; bring it up with whoever prescribes them.
Sex therapy and counseling
Mayo Clinic lists counseling and sex therapy, including cognitive behavioral therapy, as treatments that can untangle the pain-fear loop and help partners talk about it. If shame is riding shotgun, our post on unlearning sexual shame might help, too.
Pleasure Tools for the Meantime
You don't have to put pleasure on pause while you heal. Here's your toolkit:
- Lube, lube, lube. Reapply generously. In a large Indiana University diary study, lube use was linked to higher pleasure and satisfaction, and water-based lube in particular to fewer reports of genital pain.
- Skip the "sensation" formulas for now. Warming, tingling, and cooling lubes can be fun on a good day but may irritate tissue that's already upset. Fragrance-free and glycerin-free options are gentler bets.
- Take penetration off the throne. Massage, kissing, oral, mutual masturbation, and external vibration all count as sex. Mayo Clinic suggests exactly this kind of play while sex is painful.
- Use external vibration to warm up. More arousal usually means more natural lubrication and more relaxed muscles. A small bullet on the clit, perineum, or shaft is a great opening act.
- Let the receiving partner drive. Positions where whoever is receiving controls depth and speed (like being on top) make it easier to stop, slow down, or adjust.
- Agree on a stop word. Consent isn't one-and-done. "Pause," "slower," or a squeeze of the hand should be met with zero sulking.
From our Indigenous perspective, this is body sovereignty in action. Your body gets the final say on what feels good, and listening to its "not like that" is a form of respect, not failure.
When to See a Healthcare Provider
Book an appointment if pain keeps happening, gets worse, comes with bleeding, unusual discharge, sores, fever, or a new lump or bend, or if it's making you avoid intimacy. You can ask specifically for a referral to a gynecologist, urologist, or pelvic floor physical therapist. If your first provider waves you off, a second opinion is completely fair. Bring notes on where it hurts, when, and what makes it better or worse; it speeds things up.
Quick Answers
Is it normal for sex to hurt sometimes?
Occasional mild discomfort, say from a new position or rushing things, happens to lots of people. Pain that keeps coming back isn't something you have to accept, and it's worth checking out.
What is the most common cause of painful sex?
It varies, but dryness is one of the biggest factors in survey research, followed by things like infections, pelvic floor tension, low estrogen, and conditions like endometriosis. Often more than one cause is involved.
Can lube really help with painful sex?
For many people, yes. Research links lube use with more pleasure and less genital pain, but if pain continues even with plenty of lube, see a provider to rule out other causes.
Does testosterone make sex painful?
It can for some people. Research on trans men and transmasculine people links current testosterone use to more vaginal or frontal-opening pain, and a trans-competent clinician can talk you through treatment options.
