The short answer: painful sex after 40 is common, it has a clear medical cause in most cases, and it is treatable, not something to quietly endure. The usual driver is genitourinary syndrome of menopause (GSM), the cluster of changes that falling estrogen (oestrogen) brings to the vulva, vagina and urinary tract: thinning tissue, dryness, loss of elasticity and a shift in pH. That is why intercourse that once felt fine can start to burn, sting or feel like tearing. Other things can contribute too, from a tense pelvic floor to a skin condition or infection. The important part is that each cause has a real treatment, and many women feel markedly better within weeks of the right one.<\/p>\n
If you have found yourself dreading rather than wanting closeness, wincing partway through, or quietly steering clear of sex altogether, you are not broken and you are not alone. Many women describe feeling too embarrassed to raise it, and clinicians often do not ask, so it goes unspoken on both sides. Estimates suggest only around a quarter of women affected ever seek help. That silence is the real problem here, because the discomfort itself usually responds well once it is named and addressed.<\/p>\n
Dyspareunia is the medical word for persistent or recurrent pain with sex. It is a symptom, not a diagnosis, and after 40 the most common thing sitting underneath it is genitourinary syndrome of menopause. GSM is the current umbrella term, adopted by The Menopause Society, for what used to be called vaginal atrophy. It describes what happens to estrogen-dependent tissue when the hormone declines.<\/p>\n
Estrogen keeps the vaginal walls thick, elastic and well lubricated, maintains blood flow, and supports an acidic pH that keeps the local environment healthy. As estrogen falls through perimenopause and menopause, the tissue becomes thinner, drier and less stretchy, and the pH rises. The result can be dryness, burning, itching, a raw or tender feeling, and pain with penetration. Unlike hot flashes (hot flushes), which usually ease over time, GSM tends to be progressive and does not resolve on its own, which is exactly why it is worth treating rather than waiting out.<\/p>\n
For most women over 40, the leading cause of painful sex is GSM. When the vaginal lining is thinner and produces less natural lubrication, friction that used to be comfortable becomes irritating, and the tissue is more fragile and prone to tiny tears. Reduced elasticity means the vaginal opening and canal do not accommodate as easily, so entry itself can sting or feel tight. A higher pH also makes irritation and urinary symptoms more likely.<\/p>\n
This is a physical, hormonal change, not a reflection of desire or of a relationship. It is also worth separating from arousal: even when you feel interested, the tissue may not respond the way it once did, and natural lubrication may arrive more slowly or in smaller amounts. That mismatch can be confusing and disheartening, but it is a mechanical and hormonal issue with mechanical and hormonal solutions. Our companion guide to vaginal dryness and GSM<\/a> goes deeper on the tissue changes and everyday relief.<\/p>\n GSM is common, but it is not the only reason sex can hurt, and assuming it is the whole story can leave a treatable problem unaddressed. Because the treatments differ, it helps to see the main contributors side by side, along with the kind of help each one points towards.<\/p>\nThe other causes worth ruling in or out<\/h2>\n
