Why Does Sex Hurt? Common Causes

If sex has started to hurt, you're not alone — and you're not stuck.

Pain during sex is one of the most common experiences women report, and one of the least talked about. Most women suffer in silence for months or even years before they mention it to anyone. Some never do.

That stops here.

First, know this: pain during sex is a symptom, not a sentence.

It's your body communicating that something has changed and needs attention. That's actually useful information — if you know what to do with it.

The most common reasons sex hurts

Lack of lubrication This is the number one culprit and the most fixable. Natural lubrication decreases with age, stress, hormonal changes, certain medications, and even dehydration. If things have gotten drier than they used to be, that's not failure — that's biology. A good quality lubricant can change everything, sometimes immediately.

Hormonal changes Estrogen plays a big role in keeping vaginal tissue healthy, flexible, and comfortable. As estrogen drops — during perimenopause, menopause, postpartum, or even from hormonal birth control — tissue can become thinner and more sensitive. This is called vaginal atrophy and it sounds scarier than it is. It's common, it's treatable, and your doctor can help.

Vaginismus This is an involuntary tightening of the vaginal muscles that makes penetration painful or impossible. It can be triggered by anxiety, past trauma, or simply never being addressed. It responds well to treatment — this is not permanent.

Infection or skin conditions Sometimes pain has a straightforward medical cause — a yeast infection, bacterial vaginosis, or a skin condition like lichen sclerosus. If pain is new and sudden, a visit to your doctor is always the right first step.

Endometriosis Deep pain during sex can sometimes signal endometriosis, a condition where tissue similar to the uterine lining grows outside the uterus. If you experience deep pelvic pain during or after sex, bring it up with your gynecologist.

What you can do right now

Start with lubrication. A high quality water-based or silicone-based lubricant is the single most accessible first step and helps a significant percentage of women immediately.

Talk to your doctor. Pain during sex deserves a conversation at your next appointment — or sooner. You don't have to minimize it or mention it as an afterthought. It's a legitimate health concern.

Give yourself permission to slow down. Rushing past discomfort doesn't fix it. Your comfort matters.

You deserve to feel good.
