Why Sex Can Hurt Even When Everything Looks "Normal"

"Your tests are normal."
For many people experiencing pain during sex, these words are both reassuring and incredibly frustrating.
On one hand, it's good news that there isn't an infection, tear, or serious medical condition. But on the other hand, you're still left wondering:
"If everything is normal... why does it hurt so much?"
The reality is that pain during sex is common, but it's
not something you should simply put up with. And importantly, normal test results don't mean your pain isn't real.
In many cases, pain during sex is related to how the muscles, nerves, and tissues are functioning—not just how they look.
Is it normal for sex to hurt?
No.
While temporary discomfort can happen from time to time,
pain that is ongoing, recurrent, or causes you to avoid intimacy is not considered normal.
Pain during sex can affect people of all ages and may occur:
- at the entrance of the vagina
- with deeper penetration
- during certain positions
- after intercourse
- or even for hours afterwards.
No matter where or when it occurs, persistent pain deserves assessment.
Why can everything look "normal" but still hurt?
Many conditions that cause pain don't show up on scans, blood tests, or routine examinations.
Think about a tension headache. Your brain scan would usually be normal—but that doesn't make the pain any less real. The same can happen with the pelvic floor.
Your muscles may be:
- overly tight
- difficult to relax
- sensitive to touch
- uncoordinated
- protecting the area after previous pain, injury, childbirth, or surgery.
These changes are about function, not necessarily structure.
The pelvic floor's role in painful sex
Your pelvic floor muscles form a supportive sling at the base of your pelvis.
For comfortable penetration, these muscles need to:
- relax
- lengthen
- coordinate with breathing
- respond appropriately to movement.
If they remain tense or become protective, penetration may feel:
- sharp
- burning
- stretching
- like "hitting a wall"
- or simply impossible.
This doesn't mean the muscles are weak—it often means they're working too hard.
Stress can affect your pelvic floor
Stress doesn't just affect your mind—it affects your body.
When we're stressed or anxious, we often unconsciously:
- clench our jaw
- tense our shoulders
- hold our breath
- tighten our abdominal muscles
- brace our pelvic floor.
Over time, this constant muscle guarding can contribute to persistent pelvic tension and discomfort. That doesn't mean the pain is psychological. It means your nervous system and muscles are closely connected.
Other factors that may contribute
Pain during sex is often influenced by more than one factor.
These may include:
- previous painful experiences
- childbirth
- pelvic surgery
- hormonal changes
- endometriosis
- bladder pain
- bowel dysfunction
- constipation
- menopause
- skin conditions
- nerve sensitivity
- persistent muscle tension.
A thorough assessment considers all of these—not just one possible cause.
"It's all in your head"—a harmful myth
One of the most upsetting things people hear is that because their tests are normal, the pain must be psychological. That's simply not true. Pain is always real. Even when scans or examinations don't identify a structural problem, your nervous system, muscles, connective tissues, and movement patterns can all contribute to ongoing symptoms. Understanding what's driving your pain is the first step towards improving it.
How can a pelvic floor physiotherapist help?
A pelvic floor physiotherapist doesn't just look for weakness.
They assess how your pelvic floor muscles:
- relax
- contract
- coordinate
- respond during breathing and movement
- contribute to your symptoms.
Depending on your individual needs, treatment may include:
- education about pelvic pain
- breathing and relaxation strategies
- pelvic floor muscle down-training
- gentle manual therapy where appropriate
- movement and stretching exercises
- bladder and bowel advice
- strategies to reduce muscle guarding.
If another condition is suspected, your physiotherapist may also work alongside your GP, gynaecologist, or other healthcare providers to ensure you receive comprehensive care.
Frequently Asked Questions
Can tight pelvic floor muscles cause pain during sex?
Yes. An overactive or tight pelvic floor can make it difficult for the muscles to relax during penetration, contributing to pain or discomfort. A pelvic floor assessment can determine whether muscle tension is playing a role.
Why do my scans keep coming back normal?
Many causes of painful sex relate to how muscles and nerves function rather than changes that appear on imaging. Normal scans are reassuring, but they don't rule out pelvic floor dysfunction or other functional causes of pain.
Should I keep having sex if it hurts?
Persistent pain during sex shouldn't be ignored. Continuing to push through pain can sometimes reinforce muscle guarding and fear of pain. It's important to seek assessment so the underlying cause can be identified and managed appropriately.
The Bottom Line
Pain during sex is common—but it isn't something you have to accept as "normal." If you've been told that everything looks fine but intimacy is still painful, know that your experience is valid. Many causes of painful sex involve the way your muscles, nerves, and tissues are functioning, and these issues often won't show up on routine tests.
A pelvic floor physiotherapist can help identify the factors contributing to your symptoms and work with you to develop a personalised treatment plan, so you can move towards comfortable, confident intimacy again.
You deserve answers—not just reassurance that your tests are normal. If pain during sex is affecting your quality of life or relationships, book an assessment with one of our pelvic health physiotherapists to take the first step towards understanding and treating the cause.
