Painful sex is never something to simply accept or push through. It has causes — almost all of which are identifiable and most of which are treatable. Seeking help for painful sex is not an overreaction. It is the correct and appropriate response to a legitimate health concern.Dyspareunia — the medical term for persistent or recurrent pain during sexual activity — is more common than many people realise and vastly underreported. Many women endure painful sex for months or years without seeking help, assuming it is normal, inevitable or something they should be able to manage. It is none of these things. Pain during sex signals that something needs attention.
The Most Common Causes
Vaginal dryness. The most common cause of painful sex in women, particularly during and after menopause. Insufficient lubrication causes friction that produces pain, tearing and soreness. Directly and effectively addressed with quality water-based lubricant during sex and vaginal moisturiser for ongoing comfort. Vaginal oestrogen addresses the underlying tissue changes for persistent GSM-related dryness.
Vaginal atrophy (GSM). Thinning, drying and inflammation of vaginal tissue from declining oestrogen. Produces dryness, reduced elasticity and pain with penetration. Treated with vaginal oestrogen, dilators and lubricant — see our guide to vaginal atrophy for full detail.
Vaginismus. Involuntary contraction of the pelvic floor muscles in response to attempted penetration, making insertion painful or impossible. A recognised condition treated with pelvic floor physiotherapy, dilator therapy and psychological support — highly responsive to appropriate treatment.
Vulvodynia. Chronic vulvar pain without an identifiable cause — burning, stinging or irritation at the vaginal opening. Managed through a combination of topical treatments, physiotherapy and psychological support.
Infection. Thrush, bacterial vaginosis and sexually transmitted infections all cause pain, irritation and discomfort during sex. These require specific medical treatment — a GP or sexual health clinic can assess and prescribe.
Endometriosis. A significant cause of deep pelvic pain during sex for many women — pain felt deeper inside rather than at the entrance. Requires medical assessment and management.
Never Just Push ThroughPersistent pain during sex requires a GP visit, not accommodation. Pushing through pain without addressing its cause can worsen the underlying condition and creates negative associations with sex that are themselves difficult to reverse.
Lubricant Is First LineFor dryness-related pain, a quality water-based lubricant applied generously to both the vaginal opening and the dilator or partner is the most immediate intervention. More than you think you need. If this does not fully resolve pain, see a GP.
Pelvic Floor PhysiotherapyFor vaginismus, pelvic tension and post-surgical pain, a pelvic floor physiotherapist is the most effective specialist. Referral via GP. Also available privately — very high success rates with appropriate presentation.
Tell Your GP AccuratelyDescribe pain precisely: where it is (entrance, deeper inside), when it occurs (on penetration, during thrusting, after sex), how long it has been happening and what makes it better or worse. This information guides accurate diagnosis.
Pain Reduces DesireOne of the most reliable consequences of persistent painful sex is the gradual suppression of desire — the body learns to avoid the experience that causes pain. Treating the pain typically restores desire significantly.
Tell Your PartnerIf sex has become painful, tell your partner rather than accommodating it silently. Silence produces guessing and misinterpretation. Your partner needs to know in order to adjust, support and accompany you through addressing the cause.

When to See a GP
See a GP promptly if: sex has become consistently painful despite generous lubricant use; you have deep pelvic pain during sex; you have bleeding after sex; you have unusual discharge alongside painful sex; you have been unable to have penetrative sex at all; or painful sex is affecting your relationship or quality of life significantly.
All of these warrant assessment rather than accommodation. A GP can assess for infection, refer to a pelvic floor physiotherapist, prescribe vaginal oestrogen, refer to a gynaecologist for deeper assessment and discuss all available options. None of these conversations should feel embarrassing — they are routine clinical discussions that GPs conduct regularly.
The Psychological Component
Persistent painful sex has psychological consequences alongside physical ones. The anticipation of pain produces anxiety and tension that can make pelvic floor muscles contract, which increases pain — a cycle that often persists even after the original physical cause has been treated. This is why addressing painful sex often involves both physical treatment and psychological support, including sex therapy where fear and avoidance patterns have become established. A GP or gynaecologist can advise on the full range of support appropriate to your situation.
Frequently Asked Questions
What causes painful sex?The most common causes are vaginal dryness (directly addressable with lubricant), vaginal atrophy from declining oestrogen (treated with vaginal oestrogen), vaginismus (treated with pelvic floor physiotherapy and dilators), vulvodynia, infection (requires specific medical treatment) and endometriosis (requires medical management). Accurate cause determines appropriate treatment.
Should sex be painful?No. Pain during sex is not normal and should not be accommodated. It signals that something needs attention. Most causes of painful sex are identifiable and treatable. Seeking help is the correct response to persistent pain during sex.
What helps with painful sex?This depends on the cause. Generous water-based lubricant addresses dryness-related pain immediately. Vaginal oestrogen treats the underlying tissue changes of GSM. Pelvic floor physiotherapy treats vaginismus and pelvic tension. Infections require specific medical treatment. A GP can assess and direct appropriate treatment for each cause.
When should I see a GP about painful sex?When sex is consistently painful despite generous lubricant use; when you have deep pelvic pain during sex; when there is bleeding after sex; when unusual discharge accompanies painful sex; when you have been unable to have penetrative sex; or when painful sex is significantly affecting your relationship or quality of life.
Does painful sex affect desire?Yes — consistently and significantly. The body learns to associate sexual situations with pain, reliably suppressing desire in anticipation of the experience. This is one of the most important reasons to address painful sex rather than accommodate it — treating the pain typically restores desire substantially.
