Painful sex is common, but it isn’t something you have to accept as normal. An estimated 10% to 20% of women in the U.S. experience it, and men can be affected too. Pain during sex almost always has an identifiable cause, and most of those causes are treatable. Whether the pain is sharp, burning, or a deep ache, it’s your body signaling that something needs attention.
Where You Feel the Pain Matters
Pain during sex generally falls into two categories, and the distinction helps narrow down what’s going on. Entry pain (sometimes called superficial pain) happens right at the vaginal opening during initial penetration. It often feels like burning, stinging, or tightness. Deep pain, by contrast, is felt further inside the pelvis during thrusting and may be worse in certain positions.
These two types of pain tend to have very different causes. Entry pain is more commonly linked to issues with the skin, muscles, or lubrication at the vaginal opening. Deep pain is more often connected to conditions affecting the uterus, ovaries, or surrounding tissues. Both are worth investigating, but knowing which one you’re experiencing gives you a useful starting point for a conversation with a healthcare provider.
Common Causes of Pain at Entry
The most straightforward explanation is insufficient lubrication. This can happen if arousal is rushed, but it also has physiological causes that have nothing to do with desire. Hormonal shifts during breastfeeding, perimenopause, and menopause reduce the body’s natural moisture production. After menopause, lower estrogen levels cause the vaginal canal to become thinner, drier, and less stretchy, a condition sometimes called genitourinary syndrome of menopause. Blood also fills the genitals more slowly during arousal as you age, which can reduce sensitivity and make the tissue feel less ready for penetration.
Infections are another frequent culprit. Yeast infections and bacterial vaginosis cause inflammation and irritation that make any contact with the vaginal opening uncomfortable. STIs like herpes or genital warts can produce sores or lesions that sting during sex. Skin conditions like dermatitis can also affect the vulva and create persistent itching or rawness that flares with friction.
Then there’s a condition called vaginismus, where the muscles around the vaginal opening tighten or spasm involuntarily when penetration is anticipated or attempted. You can’t control these contractions. They can range from mildly uncomfortable to intensely painful, and they often create a self-reinforcing cycle: the fear of pain triggers muscle tightening, which causes more pain, which deepens the fear. Vaginismus can develop after a painful experience, but it sometimes appears without an obvious trigger.
What Causes Deep Pain
Deep pain during sex points toward conditions further inside the pelvis. Endometriosis, where tissue similar to the uterine lining grows outside the uterus, is one of the most well-known causes. It can make certain positions feel like a sharp, stabbing sensation deep inside. Pelvic inflammatory disease, ovarian cysts, and uterine fibroids can all produce similar deep aching or pressure.
Structural differences play a role too. A retroverted (tilted) uterus or uterine prolapse can change the angle of penetration in ways that cause discomfort. Irritable bowel syndrome, bladder inflammation, and hemorrhoids can also contribute, since the pelvic organs are closely packed and inflammation in one area often affects the others.
Scarring from pelvic surgery, including hysterectomy, is another source of deep pain. Cancer treatments like radiation and chemotherapy can change vaginal tissue in ways that persist long after treatment ends.
The Role of Anxiety and Emotions
Pain during sex is physical, but psychological factors can amplify it significantly. Research on women with chronic vulvar pain found that on days when they reported higher anxiety and depressive symptoms than usual, they also reported greater pain and lower sexual function. This wasn’t imagined pain. Anxiety increases muscle tension throughout the body, including the pelvic floor, and heightened stress hormones can lower arousal and lubrication.
Past trauma, relationship stress, and performance anxiety can all feed into this cycle. The brain’s threat-detection system doesn’t distinguish neatly between physical danger and emotional distress, so feeling unsafe or pressured can produce real, measurable changes in how your body responds to touch. This doesn’t mean the pain is “in your head.” It means the nervous system is involved, which is true of all pain.
Painful Sex in Men
Though less commonly discussed, men experience painful sex too. Tight foreskin (phimosis) can cause pain during penetration. Prostatitis, an inflammation of the prostate gland, often causes pain during or after ejaculation. It can result from bacterial infection, including sexually transmitted infections, though in many cases the exact cause is harder to pin down. Skin conditions on the penis, urinary tract infections, and Peyronie’s disease (a buildup of scar tissue that curves the penis) are other potential sources of pain.
How Pelvic Floor Therapy Helps
For many people with painful sex, especially those dealing with vaginismus, pelvic floor tension, or chronic vulvar pain, pelvic floor physical therapy is one of the most effective treatments available. A pelvic floor therapist works with you to retrain the muscles of the pelvic floor, improving both strength and the ability to relax. For pain conditions specifically, the goal is to reduce resting muscle tension, increase vaginal elasticity, and build awareness of when those muscles are clenching.
Most therapists recommend weekly hour-long sessions, typically four to eight sessions to start, combined with exercises you do at home. Research from Stanford Medicine found that women with vestibular pain showed measurable improvements after eight sessions: less pelvic floor tension, better vaginal flexibility, and improved muscle control. In another study, patients who received twice-weekly internal massage therapy saw pain scores improve after five weeks, with benefits lasting up to four and a half months after treatment ended. Depending on the severity of symptoms, some people continue therapy for several months.
Other Approaches That Help
Treatment depends entirely on the underlying cause. If dryness is the issue, a water-based or silicone-based lubricant can make an immediate difference. For hormonal causes like menopause-related vaginal changes, topical estrogen therapy can restore moisture and elasticity over time. Infections clear up with appropriate treatment, and once the inflammation resolves, pain typically does too.
For conditions like endometriosis, fibroids, or ovarian cysts, treatment may involve hormonal management or, in some cases, surgery. Adjusting sexual positions to control the depth of penetration can also reduce deep pain while you’re working on the underlying cause.
When anxiety or past trauma are part of the picture, working with a therapist who specializes in sexual pain can help break the fear-tension-pain cycle. Some people benefit from a combination of pelvic floor therapy and psychological support, addressing both the muscular and emotional components at once.
Pain That Deserves Prompt Attention
Occasional mild discomfort from a new position or not enough lubrication is one thing. But pain that happens repeatedly, gets worse over time, or is accompanied by unusual bleeding, fever, or new discharge is worth getting evaluated sooner rather than later. Sudden, severe pelvic pain during or after sex can indicate an ovarian cyst rupture or ectopic pregnancy, both of which need urgent care. Persistent burning or rawness after sex that doesn’t resolve within a day or two also warrants a visit, since it may point to an infection or skin condition that’s easy to treat once identified.
