Why Sex Hurts: A Guide to Dyspareunia

Where the pain is changes what it points to

Entry pain (right at penetration) and deep pain (with deep thrusting) point toward different things, and naming which one you have is often the single most useful piece of information you can give a provider.

Entry pain more often traces to: vaginismus (involuntary tightening of the pelvic floor muscles, very treatable with pelvic floor physical therapy), vulvodynia — especially the provoked, entrance-specific subtype called vestibulodynia — insufficient arousal or lubrication, vaginal dryness from low estrogen (perimenopause, menopause, postpartum, breastfeeding, or certain hormonal contraception), or an active infection like a yeast infection or bacterial vaginosis.

Deep pain more often points toward endometriosis, pelvic floor muscle tension higher up, ovarian cysts, fibroids pressing on nearby structures, or pelvic organ prolapse.

The pattern matters too

Pain present from the very first time you tried penetration (primary dyspareunia) versus pain that started after a stretch of pain-free sex (secondary) points toward different causes. Primary leans toward vaginismus or an anatomic factor present from the start; secondary toward something that changed — menopause, childbirth, a new infection, endometriosis progressing, or a new medication.

Pain that's actually constant, regardless of sexual activity, or that reads more like vulvar burning or rawness than a sharp pain specifically with penetration, is worth describing to a provider in exactly those terms — it changes what gets considered first, and "it hurts during sex" alone can undersell what's actually going on.

The conditions behind it, read in more depth elsewhere on this site

Vulvodynia is chronic vulvar pain without an obvious cause — frequently mistaken for recurrent yeast infections and treated with antifungals that don't help, sometimes for years, before the real diagnosis is considered.

Vaginal dryness and GSM (genitourinary syndrome of menopause) causes pain through an actual, mechanical, treatable drop in estrogen to the tissue — not something to just live with, and local vaginal treatment avoids most of the systemic-hormone concerns people assume apply.

Endometriosis is one of the more common causes of deep pain with sex specifically, alongside the period pain it's more commonly associated with.

Vaginitis — yeast, bacterial vaginosis, and several other causes that look similar but need different treatment — can make sex actively painful while it's active, and resolves once correctly diagnosed and treated.

Pelvic floor physical therapy is the one thread running under several of these at once: it's a first-line treatment for vaginismus and vulvodynia specifically, and often a useful adjunct for the deep-pain causes too, not just a fallback when nothing else has worked.

Why this gets missed, and why it's worth pushing on

A lot of people are told to just relax more, or get a response that only addresses lubrication without exploring further. If a first conversation doesn't actually help, it's worth asking specifically for a referral to a provider who specializes in sexual or pelvic pain — urogynecology, a vulvar health specialist, or pelvic floor physical therapy — rather than concluding nothing can be done.

This also isn't only a later-in-life issue. Vaginismus and vulvodynia commonly start in the teens and twenties, well before menopause-related dryness becomes relevant — age alone shouldn't be the thing that determines whether this gets taken seriously.
