Pain during sex affects more women than is often acknowledged. Many women experience it for months or years before seeking help, frequently assuming it is something they must simply tolerate. In the majority of cases, pelvic floor dysfunction is a treatable underlying cause, and most women see meaningful improvement with the right support.
At PhysioReform, our women’s health physiotherapy service in Bloomsbury is designed specifically to assess and treat these issues. This article explains what tight pelvic floor symptoms actually mean, why they occur, and how physiotherapy can help.
What pelvic floor dysfunction is and how it can cause pain during sex
The pelvic floor is a group of muscles that runs across the base of the pelvis. These muscles support the bladder, bowel, and uterus. They also play a central role in sexual function, controlling muscle tension during penetration and contributing to both comfort and sensation.
Most people associate pelvic floor problems with weakness, such as leaking urine after childbirth. But muscles can also become too tight, too rigid, or unable to relax properly. When the pelvic floor is overactive, penetration triggers a protective muscle contraction rather than a release. The result is pain, a sensation of pressure, or an inability to tolerate penetration at all.
This is sometimes called vaginismus or dyspareunia, though in practice these overlap. The common thread is muscle guarding that the nervous system has learnt as a protective response. That response can be unlearnt.
What are the symptoms of a tight pelvic floor?
Tight pelvic floor symptoms include pain during penetration, difficulty inserting tampons, urinary urgency, pelvic pressure or heaviness, lower back discomfort, and constipation. The pelvic floor muscles are overactive and unable to relax fully, which causes pain and dysfunction across multiple areas.
Beyond pain during sex, tight pelvic floor symptoms can show up in ways that seem entirely unrelated. Recognising the full picture often helps women connect the dots more quickly.
Common presentations include:
- Pain or burning during or after intercourse
- Difficulty or discomfort inserting tampons or a menstrual cup
- Urinary urgency, or needing to rush to the toilet suddenly
- A sensation of pelvic heaviness or pressure
- Constipation or straining to open the bowels
- Lower back or hip ache that does not respond to standard treatment
- Aching in the coccyx (tailbone) or sit bones
Not every woman will experience all of these. Some notice one or two symptoms that have been present for years. Others develop symptoms suddenly following a stressful period, surgery, or childbirth.
If you are also experiencing chronic pelvic pain in addition to these symptoms, pelvic floor assessment is a sensible first step.
Why pelvic floor muscles become overactive
Overactive pelvic floor symptoms do not usually develop without reason. Several factors can cause the muscles to hold excess tension, and in many women it is a combination rather than a single cause.
Stress is a significant contributor. The pelvic floor responds to psychological pressure in much the same way as the jaw or shoulders, by bracing. Over time, that bracing can become the default resting state.
Other common triggers include:
A history of chronic pelvic pain or endometriosis
Childbirth, particularly following a difficult labour, perineal tearing, or instrumental delivery
Hormonal changes during perimenopause and menopause, which alter tissue elasticity and nerve sensitivity
Prolonged sitting, common in desk-based work
High-impact or high-intensity exercise without adequate pelvic floor awareness
Previous pelvic surgery or infection
Anxiety about sex or a history of trauma
For women in the perimenopause transition, pelvic physiotherapy for menopause addresses these changes specifically. Oestrogen decline affects pelvic tissue directly, and this is often overlooked in general healthcare settings.
In clinic, we often see women who have been told their pain is hormonal and offered lubricant or HRT, without anyone assessing the muscular component. Both may be relevant, but if the muscles are guarding, that needs to be addressed separately.
How do you fix an overactive pelvic floor?
An overactive pelvic floor is treated with a combination of muscle relaxation techniques, breathing work, nervous system down-regulation, and gradual pelvic floor coordination exercises. A women’s health physiotherapist assesses what is driving the tension and creates a personalised treatment plan, which may include manual therapy and progressive desensitisation exercises.
The word ‘fix’ is a little misleading because there is no single intervention. Treatment works by helping the nervous system learn that the pelvic floor can relax safely.
Sessions typically focus on:
- Diaphragmatic breathing, which directly influences pelvic floor tension via the pressure system connecting the diaphragm and pelvis
- Lengthening and relaxation exercises, not strengthening, in the early stages
- Postural and movement assessment to identify habits that maintain tension
- Gradual progressive desensitisation, which might involve dilator therapy if penetration has become very difficult
- Education about the pain cycle and how to break it
Strengthening is introduced later, and only once the muscles can relax properly. Giving someone with an overactive pelvic floor more Kegel exercises is the wrong approach and can make symptoms worse.
The NHS guidance on pelvic pain recommends seeking assessment if pelvic pain is persistent. Physiotherapy is a recognised part of the treatment pathway.
What pelvic floor physiotherapy treatment involves
The first appointment at PhysioReform is a full assessment, typically lasting 45 to 60 minutes. There is no pressure to rush, and nothing will happen without your consent at every stage.
The session usually includes:
- A detailed discussion of your symptoms, medical history, and any previous treatment
- A movement and posture assessment to look at how the whole system is functioning
- An optional internal examination, which is offered only when clinically appropriate and always with explicit consent
- A personalised treatment plan with clear goals and realistic timelines
One patient who came to us following her second vaginal birth had been experiencing pain during intercourse for over a year. She had been advised by her GP to simply give it more time. Her assessment revealed significant pelvic floor guarding, tightness in the hip rotators, and altered breathing patterns. Within eight weeks of targeted treatment, she was largely pain-free. Her progress was not unusual.
For more on conditions that can be associated with pelvic floor dysfunction, the NHS information on urinary incontinence and pelvic floor exercises provides a helpful overview of how pelvic floor health connects to multiple functions.
If you have also noticed urinary leakage, our blog on urinary leakage and when to see a pelvic floor physio covers this in more detail.
When to see a GP instead: red flags to be aware of
Pelvic floor physiotherapy is appropriate for musculoskeletal causes of pelvic pain and sexual dysfunction. However, some symptoms need medical investigation first. Please contact your GP promptly if you experience:
- Unexplained vaginal bleeding, particularly between periods or after the menopause
- Fever accompanied by pelvic pain
- Sudden or severe pelvic pain that is new or significantly worse than usual
- Unexplained weight loss
- Blood in urine without a clear cause
- Any neurological symptoms such as numbness, leg weakness, or loss of bowel or bladder control
Our blog on pelvic pain in women: causes, red flags, and treatment options explores this in more depth, including when imaging or specialist referral may be appropriate.
