Sex that hurts is common, and almost all of it is treatable

Most women who have sex that hurts assume two things. That it is probably their fault, and that they are unusual. Both are wrong, and the second one is wrong by a very wide margin.

Pain during sex is one of the most common physical complaints in women’s health and one of the least often treated properly. It happens in the twenties and in the seventies. It has a short list of causes, most of which can be identified in a single appointment by someone who asks the right question, and most of which respond to treatment.

What painful sex actually is

The medical term is dyspareunia, which just means pain during or after sex.² It is a description, not a diagnosis. Nobody should be sent away with that word and nothing else.

The useful distinction is between pain that was always there, from the first attempt at penetration, and pain that started after a period of comfortable sex. The first points towards muscle guarding, skin conditions or anatomy. The second points towards something that changed: a birth, a surgery, an infection, a new medication, menopause, or a stretch of pain that taught the body to brace.

How common this is

A large minority of women report pain with sex currently, and a clear majority report it at some point in their lives. After menopause that figure rises steeply, because tissue changes affect nearly everyone to some degree.¹⁷

The isolation does real damage. Women who think they are the only one do not raise it, and a problem that is never raised is never treated.

Where it hurts tells you most of what is needed

If you bring one piece of information to an appointment, bring the location. It narrows the list faster than any test.

Pain at the entrance, felt on first contact or during entry, is a different problem from pain felt deep inside on thrusting or in certain positions. Entry pain usually involves the skin, the tissue or the muscles at the opening. Deep pain usually involves an organ or a structure that is being pushed against.

Some women have both, and that combination is common in longstanding cases, because deep pain teaches the entrance muscles to guard.

Entry pain when the tissue is dry or thin

The most frequent cause of entry pain is straightforward friction. Tissue that is not lubricated enough, or tissue that has become thinner and less elastic, produces a burning or raw sensation during and often for a day or two afterwards.

Two situations account for most of this. The first is not being aroused enough before penetration, which is a timing problem rather than a fault. The second is low estrogen, which thins the tissue and reduces natural lubrication. That happens around and after menopause, during breastfeeding, and in some women on hormonal contraception.⁶

The second version does not improve with lubricant alone, because lubricant treats the surface and not the tissue. Local vaginal estrogen does, and it works well.

Entry pain when the muscles close

The muscles around the vaginal opening can tighten involuntarily to the point that penetration is painful or impossible. This is vaginismus, and it is not something a woman chooses or can simply decide to stop.¹

It can be there from the start, so that first attempts at tampons, examinations or sex were all difficult. It can also develop later, after any experience that taught the body that penetration means pain. Once the pattern is established it becomes self-sustaining: anticipation causes tightening, tightening causes pain, pain confirms the anticipation.

This responds well to treatment, which is worth stating plainly because women with vaginismus are frequently told, wrongly, that it is psychological and permanent.

The pelvic floor can be too tight, not too weak

Almost everything women hear about the pelvic floor is about weakness. Squeeze more. Do your Kegels. That advice is correct for some problems and actively harmful for this one.

An overactive pelvic floor is a set of muscles that never fully lets go. They sit at partial contraction all the time, the way a clenched jaw does. The result is pain on entry, aching afterwards, sometimes urinary urgency, sometimes constipation, sometimes lower back or hip pain that nobody connects to the same source.⁴

Telling a woman with an overactive pelvic floor to strengthen it makes her worse. This is one of the more common and more fixable mistakes in the whole field.

A muscle that hurts is not always a weak muscle. Sometimes it is a muscle that has forgotten how to stop working.

The reframe that changes treatment

Deep pain and what it points to

Pain felt deep inside, particularly in specific positions or with deeper penetration, suggests something is being contacted that does not like being contacted.

Endometriosis is the cause most worth knowing about, because it is common and takes years to diagnose. Its version of painful sex is typically deep, often worse around your period, and frequently accompanied by period pain that is out of proportion and by pain with bowel movements at certain times of the month.⁷

Fibroids and ovarian cysts can produce deep pain by position.²² So can pelvic organ prolapse, and so can adhesions after abdominal surgery or a caesarean. Bowel conditions such as irritable bowel syndrome cause deep pain often enough that the pattern is worth noticing.

Infections cause pain that arrives suddenly

Pain that started recently, especially alongside a change in discharge, smell, itching or burning when you urinate, is likely to be an infection. Thrush and bacterial vaginosis both do this and both are simple to treat.¹¹

Pelvic inflammatory disease matters more. It causes deep pain with sex, ongoing pelvic pain, abnormal discharge and sometimes fever, and it needs prompt antibiotics because untreated it can affect fertility.⁹ New deep pain with any of those companions is not something to wait out.

Pain with nothing visible to find

Some women have persistent pain at the vulva with no infection, no skin change and a normal examination. This is vulvodynia, and it is a real condition rather than a diagnosis of exclusion made out of politeness.⁵

The typical description is burning, rawness or stinging, either constant or triggered only by touch and pressure. The version triggered by pressure is often diagnosed with a cotton bud, by mapping which specific points at the entrance are tender. That test takes two minutes and is skipped constantly.

Treatment usually combines pelvic floor physiotherapy, topical treatments and sometimes medication that calms overactive nerve signalling. It works, though slowly.

Skin conditions that get missed for years

The vulva can develop skin conditions like anywhere else, and the ones that cause pain with sex are badly underdiagnosed.

Lichen sclerosus is the important one. It causes itching, whitened or fragile skin, splitting with sex, and over time it can change the shape of the tissue. It responds well to a strong steroid ointment and needs ongoing management, so getting the name right matters.¹⁴ Women often carry it for a decade being treated for recurrent thrush that never quite resolves.

If you have been treating thrush repeatedly without success, ask someone to look at the skin properly.

Why this gets dismissed so consistently

There are three reasons, and none of them are about you.

Appointments are short and this problem takes a proper history. Sexual pain is still awkward for some clinicians to raise, so it does not get asked about unless the patient asks. And there is a lazy assumption that sexual pain in women is anxiety, which serves as an exit from a conversation that would otherwise require an examination.

The practical response is to be specific rather than apologetic. Say where it hurts, how often, when it began, and what you have already tried. Specific reports are much harder to wave away than “sex is uncomfortable”.

What a proper assessment involves

You should expect a conversation about location, timing and history, and then an examination that starts with looking before touching.

A careful examiner will inspect the skin, use a cotton bud to map tender points at the entrance, and assess the pelvic floor muscles by touch rather than going straight for a speculum. Swabs are taken if infection is plausible. An ultrasound is added when deep pain suggests something structural.

If an examination is painful, that is information, not a failure. Say so at the time, because where and when it hurt during the examination is part of the diagnosis.

The treatment most women are never offered

Pelvic floor physiotherapy is the single most under-prescribed treatment in this whole area.

It is not exercises you look up. A pelvic health physiotherapist assesses the muscles directly, then teaches release rather than strengthening when release is what is needed: breathing that lets the floor drop, manual work on tight points, graded desensitisation, and often dilators used in a structured way rather than as an ordeal to endure.

It has good results for vaginismus, for overactive pelvic floor, for vulvodynia and for pain that persists after childbirth. Ask for it by name, because it is often available and rarely mentioned.

What treatment actually looks like

For friction and dryness: a good lubricant used generously, a vaginal moisturiser used regularly rather than only during sex, and local estrogen where tissue has thinned. Local estrogen acts on the tissue itself and is a different proposition from systemic hormone therapy.

For muscle problems: physiotherapy, usually over several months, sometimes with dilators.

For endometriosis: hormonal treatment to suppress the cycle, pain management, and surgery in some cases.

For infections: the specific antibiotic or antifungal treatment, and treating a partner where that is relevant.

For skin conditions: the correct ointment and follow up.

When to be examined rather than manage this yourself

Some symptoms are not for self-management, however tempting it is to wait and see.

Bleeding after sex usually turns out to be dryness or a harmless change on the cervix. It is checked anyway, because the rare times it is something else are the times it matters. Bleeding after menopause is the single symptom in this article most worth acting on quickly.¹⁹

What a realistic few months look like

Start by writing down the pattern for two or three weeks: where, when, how bad, what was different. That is the most useful thing you can do before any appointment.

Then get assessed, asking directly for the things in the checklist above rather than waiting to be offered them.

Then give treatment the time it needs. Muscle patterns built over years do not release in a fortnight. Tissue treated with local estrogen takes several weeks to change. Endometriosis treatment is judged over cycles.

Stopping when something hurts is not giving up. Pushing through pain teaches the pelvic floor to brace harder and makes the eventual treatment longer.

A note on what this is not

Your comfort during sex is not a service you provide to anyone. A partner who treats your pain as an inconvenience has told you something useful about the relationship, and no amount of physiotherapy addresses that.

The practical move is to take penetration off the table while you are being treated. Not as a withdrawal, but because continuing to do the thing that hurts undermines every treatment described here.

The honest limits

Not every case resolves completely. Longstanding vulvodynia in particular can improve substantially without disappearing, and some women live with a level of ongoing discomfort that is managed rather than cured.

That is the minority, and it is a long way from the position most women start in, which is that nothing can be done and nobody is listening. For most causes on this list the realistic expectation is real improvement, often full resolution, from treatment that already exists and that you have to ask for by name.
