Painful Sex After 40? It's Probably GSM (and It's Treatable)

Sex isn't supposed to hurt. Peeing isn't supposed to burn unless something is wrong. And UTIs aren't supposed to keep coming back forever.

If any of that started happening sometime after your early 40s, the most likely cause is something with an unwieldy name and a straightforward fix: genitourinary syndrome of menopause, or GSM.

GSM affects somewhere between half and three-quarters of postmenopausal people. It's still wildly underdiagnosed and undertreated, partly because it's not part of the cultural shorthand for menopause (everyone hears about hot flashes; almost no one hears about this) and partly because patients don't bring it up and providers don't ask.

What GSM Is

As estrogen levels drop in late perimenopause and after menopause, the tissues of the vulva, vagina, urethra, and bladder all change. Specifically:

• Vaginal walls become thinner and less elastic
• Natural lubrication decreases
• Vaginal pH shifts, changing the bacterial environment
• Urethral and bladder tissues thin
• Pelvic floor muscles can lose tone

Symptoms include:

• Vaginal dryness
• Burning, itching, or irritation
• Painful sex (especially at penetration)
• Bleeding or spotting after sex
• Frequent or urgent urination
• Burning with urination
• Recurrent UTIs (or symptoms that feel like UTIs but cultures are negative)
• Pelvic discomfort

These symptoms tend to appear gradually and get worse over time. Unlike hot flashes, they don't go away on their own.

Why It's Underdiagnosed

A few reasons:

Patients don't bring it up. It feels embarrassing. It feels like something you're supposed to handle on your own. It gets framed as "just part of aging." It isn't.

Providers don't ask. Annual visits are short, and unless someone is asking specifically about sex or urinary symptoms, this stuff doesn't come up.

It gets misdiagnosed as recurrent UTIs. A patient comes in three times in six months with UTI-like symptoms, gets antibiotics, never feels fully better. The actual issue is often urethral atrophy from GSM, which causes the same symptoms but doesn't respond to antibiotics.

It gets framed as a "lubrication" problem. Lube helps with dryness during sex, but it doesn't address the underlying tissue changes. If someone tells you to "just use more lube," they're missing the bigger picture.

What Actually Works

Treatment options range from over-the-counter to prescription:

Vaginal moisturizers (different from lubricants) — used regularly to restore tissue hydration. Brands like Replens, Hyalo Gyn, or Revaree. These help mild cases.

Lubricants for sex — useful adjunct, but not a treatment for the underlying issue.

Vaginal estrogen — the gold standard for moderate to severe GSM. Available as cream, tablet, ring, or insert. Used 2-3 times a week after an initial loading period. Systemic absorption is minimal — vaginal estrogen has a very different safety profile than systemic hormone therapy.

Vaginal DHEA (Intrarosa) — an alternative to vaginal estrogen for patients who can't or don't want to use estrogen.

Ospemifene — an oral non-hormonal option for moderate to severe painful sex.

Pelvic floor physical therapy — for patients with significant pelvic floor involvement, often used alongside hormonal treatment.

What About Breast Cancer Survivors?

This is a common concern. Many breast cancer survivors are told they can't use estrogen — which is true for systemic estrogen in most cases. But vaginal estrogen is a separate question.

Recent guidance from major oncology and gynecology organizations has shifted toward considering low-dose vaginal estrogen for breast cancer survivors with significant GSM symptoms, in consultation with their oncologist. It's a real conversation worth having if you're in this situation.

How We Handle GSM Visits

A GSM-focused visit looks like this:

• We ask about specific symptoms — vaginal, sexual, urinary
• We do a physical exam (with your consent and at your pace) to assess tissue changes
• We rule out other causes when needed (cultures for actual UTIs, etc.)
• We discuss treatment options that fit your situation, including any past medical history that affects choices
• We start treatment and follow up to adjust

If a Pap smear or pelvic exam itself has been painful in the past — which is common with untreated GSM — we offer comfort measures including nitrous oxide and topical numbing. You shouldn't have to white-knuckle through a check-up for a problem that came from undertreated discomfort in the first place.

You Don't Have to Live With This

The single biggest barrier to GSM treatment is patients not knowing it's a thing — or not knowing it's treatable. If anything in this post sounded familiar, please bring it up at your next visit, even if you're not sure how to start the conversation. Your provider should take it seriously. We do.

Book a GSM consultation — in office or telehealth — or send us a message. You can also read about perimenopause symptoms more broadly or hormone therapy options after the WHI study.
