Pain during sex is extremely common. About 3 out of 4 women experience it at least once, and 10% to 20% deal with it on a chronic basis. Between 1% and 5% of men report painful intercourse as well. The causes range from simple issues like insufficient lubrication to underlying medical conditions that need treatment. In almost every case, the pain has a physical explanation, and most causes are treatable once identified.
Pain at the Entrance vs. Pain Deep Inside
Where you feel the pain tells you a lot about what’s causing it. Pain felt right at the vaginal opening during initial penetration is called superficial dyspareunia, and it typically points to issues with the skin, muscles, or tissue at the entrance. Pain felt deeper inside during thrusting suggests something going on with the pelvic organs, such as the uterus, ovaries, or surrounding tissue.
Paying attention to this distinction is one of the most useful things you can do before talking to a healthcare provider. Whether the pain is sharp or burning, whether it happens every time or only in certain positions, and whether it started suddenly or gradually all help narrow down the cause.
Common Causes of Pain at the Entrance
Vaginal Dryness
This is the most frequent and most fixable cause of painful sex. Without enough natural lubrication, friction against the vaginal walls creates a burning or stinging sensation. Dryness can happen for straightforward reasons: not enough foreplay, stress, dehydration, or simply where you are in your menstrual cycle. But it can also be triggered by medications. Hormonal birth control, certain antidepressants, anti-estrogen medications used for fibroids or endometriosis, and even breastfeeding can all lower estrogen levels enough to reduce lubrication. A water-based or silicone-based lubricant often resolves the discomfort immediately, though persistent dryness may need a closer look at the underlying cause.
Infections
Yeast infections and bacterial vaginosis are two of the most common vaginal infections, and both can make penetration painful. The tissue becomes inflamed, swollen, and sensitive. Sexually transmitted infections like herpes and genital warts can also cause pain, especially if there are active sores or lesions. If the pain started recently and is accompanied by unusual discharge, itching, or odor, an infection is a likely explanation.
Skin Conditions
Any condition that causes itchy, irritated, or inflamed skin on the vulva can make sex painful. Contact dermatitis from soaps, detergents, or scented products is a common culprit. Lichen sclerosus, eczema, and other chronic skin conditions can also affect the genital area, thinning or toughening the skin in ways that make friction uncomfortable.
Vulvodynia
Vulvodynia is chronic pain in the vulvar area that lasts three months or longer without an identifiable cause like an infection or skin disease. The pain can be constant or triggered by touch, and it often makes any form of penetration difficult. It affects a significant number of women and is frequently underdiagnosed because the tissue may look completely normal on examination.
Involuntary Muscle Tightening
Vaginismus is when the vaginal muscles suddenly and involuntarily tighten up when you try to insert anything, whether that’s a tampon, a finger, or a partner. It causes a burning or stinging pain and can make penetration feel impossible. This is an automatic reaction that you don’t have control over. It’s not about willpower or relaxation. Vaginismus can develop after a painful experience, a period of anxiety around sex, or sometimes without any clear trigger. Pelvic floor physical therapy is one of the most effective approaches, gradually training the muscles to release rather than clench.
Causes of Deep Pain During Sex
When pain is felt deep inside during or after penetration, it often involves the pelvic organs or the tissue surrounding them.
Endometriosis is one of the most well-known causes. It occurs when tissue similar to the uterine lining grows outside the uterus. Research has found that the pain is strongly linked to the presence of nodules in the area behind the cervix. Women with endometriosis in that specific location are roughly five times more likely to experience painful sex than those without. The pain tends to be worst with deep penetration and may intensify around your period.
Pelvic inflammatory disease, usually caused by an untreated STI, creates inflammation in the uterus, fallopian tubes, or ovaries that makes deep penetration painful. Ovarian cysts, uterine fibroids, and conditions affecting the bladder like interstitial cystitis can all produce deep pelvic pain during sex as well. Even scar tissue from previous surgeries or infections can create areas of tenderness that get aggravated by movement during intercourse.
Hormonal Changes and Menopause
Estrogen plays a central role in keeping vaginal tissue thick, elastic, and naturally moist. When estrogen levels drop, the vaginal lining becomes thinner, drier, less elastic, and more fragile. The vaginal canal can actually shorten and tighten over time. This condition, called genitourinary syndrome of menopause, affects the majority of postmenopausal women to some degree.
The result is pain during sex due to reduced lubrication, and sometimes light bleeding afterward because the thinned tissue tears more easily. But menopause isn’t the only cause of these changes. Breastfeeding, cancer treatments like chemotherapy, and surgical removal of the ovaries all lower estrogen and can produce the same tissue changes, sometimes in much younger women. Localized estrogen therapy, moisturizers designed for vaginal tissue, and lubricants are the primary ways to manage this.
Pain During Sex for Men
While less commonly discussed, men experience painful intercourse too. The causes are different but equally varied.
Phimosis, where the foreskin is too tight to pull back over the head of the penis, creates pain during any activity that stretches or moves the foreskin. Peyronie’s disease causes a buildup of scar tissue inside the penis that leads to curvature, and that curvature can make erections and penetration painful. Skin conditions like lichen planus or balanitis (inflammation of the head of the penis) make the skin raw and sensitive.
Pain during or after ejaculation often points to prostate issues. Acute prostatitis, an infection or inflammation of the prostate, can cause a sharp or burning pain during ejaculation. Scrotal pain during sex may relate to conditions like epididymitis (inflammation of the tube behind the testicle) or varicocele (enlarged veins in the scrotum). Urinary tract infections and bladder conditions like interstitial cystitis can also make sexual activity uncomfortable for men, producing a burning sensation during or after intercourse.
How the Cause Is Identified
A healthcare provider will typically start by asking where exactly the pain occurs, when it started, and what it feels like. For women, a physical examination is usually the next step. This involves a visual check of the vulva and vaginal walls to look for signs of infection, skin changes, dryness, or inflammation. If the provider suspects an infection, a swab can confirm whether yeast, bacteria, or an STI is involved.
Deeper pain often requires additional steps like an ultrasound to check for cysts, fibroids, or endometriosis. For men, the evaluation may include a prostate exam, urine tests, or imaging depending on the location of the pain. In both cases, the more specific you can be about the type of pain and when it happens, the faster the evaluation tends to go.
What Helps
The treatment depends entirely on the cause, which is why figuring out what’s behind the pain matters more than trying to push through it. For dryness, lubricants and extended foreplay are the simplest starting points. Infections clear up with appropriate treatment, often within a week or two. Hormonal changes respond to estrogen therapy applied locally or to over-the-counter vaginal moisturizers used regularly, not just during sex.
Vaginismus and pelvic floor tightness improve with pelvic floor physical therapy, which involves learning to consciously relax the muscles and gradually becoming comfortable with penetration using dilators of increasing sizes. This process takes weeks to months, but success rates are high. For conditions like endometriosis or fibroids, treatment may involve hormonal management or, in some cases, surgery to remove the tissue causing the problem.
Changing positions can also make a real difference, especially for deep pain. Positions where the person experiencing pain controls the depth and angle of penetration tend to be more comfortable. This doesn’t fix the underlying problem, but it can make sex manageable while you’re working on a longer-term solution.
