Pain during sex is common, and it almost always points to a specific, treatable cause. The medical term is dyspareunia, which covers any persistent or recurring pain just before, during, or after sex. It affects people of all genders, though women report it more frequently. Where you feel the pain, when it happens, and what it feels like are all clues to what’s going on.
Where the Pain Happens Matters
Sexual pain generally falls into two categories, and telling them apart is the first step toward figuring out the cause. Entry pain (sometimes called superficial pain) is felt at the vaginal opening during initial penetration. Deep pain happens further inside and often feels worse in certain positions. Some people experience both.
Entry pain tends to involve the skin, muscles, or nerves near the surface. Deep pain is more likely connected to internal organs or tissues. Knowing which type you’re dealing with helps narrow the list of possible causes significantly.
Common Causes of Entry Pain
The most straightforward explanation is insufficient lubrication. This can happen from not enough arousal time, stress, certain medications (antihistamines and some antidepressants are known culprits), or hormonal changes. But when the pain persists even with adequate lubrication, something else is usually going on.
Infections like yeast infections or bacterial vaginosis can inflame vulvar and vaginal tissue, making any contact painful. These are easily diagnosed and treated, but many people tolerate the discomfort for months without realizing an infection is the source.
Skin conditions can also cause surface-level pain. Lichen sclerosus, for example, is a chronic inflammatory condition affecting genital skin. Over time it can cause scarring that makes penetration difficult or painful. It’s not an STI and it’s not contagious, but it does need treatment to prevent the scarring from progressing.
Pelvic Floor Muscle Tension
One of the most underrecognized causes of entry pain is a hypertonic pelvic floor, where the muscles in the lower pelvis are stuck in a state of constant contraction or spasm. These muscles normally relax to allow penetration, but when they can’t release, the result is a tight, burning, or blocking sensation. This condition, previously called vaginismus, can be temporary or ongoing, and it often develops in response to pain from another source. Your body learns to brace against the expected pain, and even after the original problem resolves, the muscle pattern can persist.
Common Causes of Deep Pain
Deep pain during sex often traces back to conditions affecting the uterus, ovaries, or surrounding tissues. Endometriosis is one of the most common. In this condition, tissue similar to the uterine lining grows outside the uterus, embedding itself in places like the space between the uterus and rectum, the pelvic sidewall (where major nerves run), the ligaments supporting the uterus, or even the vaginal wall. When these areas are pressed during deep penetration, the result is sharp or aching pain.
Pelvic inflammatory disease, ovarian cysts, and fibroids can all produce similar deep pain. The position-dependent nature of this type of pain is a hallmark. If certain angles or depths hurt while others don’t, that’s useful information for identifying the underlying cause.
Hormonal Changes and Vaginal Tissue
Estrogen plays a major role in keeping vaginal tissue thick, elastic, and well-lubricated. When estrogen drops, the vaginal lining becomes thinner, drier, and less stretchy. The vaginal canal can actually narrow and shorten. Blood flow to the area decreases, the natural lubrication drops, and even the acid balance shifts, making the tissue more fragile and easily irritated.
This happens most dramatically during menopause, but it also affects people who are breastfeeding, taking certain hormonal medications, or who have had their ovaries removed. The postpartum period is another vulnerable window. More than 50% of women experience pain during their first intercourse after giving birth, and roughly 41% still report pain, reduced desire, and arousal difficulties three months later.
The changes are gradual enough that many people assume it’s just something they have to live with. It isn’t. Topical estrogen, moisturizers, and other treatments can restore tissue health significantly.
Pain During Sex in Men
Painful sex isn’t exclusively a women’s health issue. Men can experience pain in the penis, scrotum, or during ejaculation, and the causes are just as varied. Phimosis, where the foreskin is too tight to retract comfortably, is one common anatomical cause. Peyronie’s disease creates a buildup of scar tissue in the penis that can cause curvature and pain during erection or penetration.
Skin conditions like balanitis (inflammation of the head of the penis) or lichen planus can make the penile skin raw or sensitive. Prostatitis, an inflammation of the prostate, frequently causes a burning or aching sensation during or after ejaculation. Scrotal conditions like varicoceles can produce a dragging pain that worsens with sexual activity.
The Psychological Layer
Pain during sex rarely stays purely physical. Anticipating pain triggers a stress response that tightens muscles, reduces arousal, and decreases lubrication, which creates more pain. This cycle can become self-reinforcing quickly. Anxiety, past trauma, and relationship stress can all amplify the physical experience of pain or, in some cases, be the primary driver.
This doesn’t mean the pain is imaginary. The nervous system’s role in processing pain is real and measurable. It does mean that addressing the emotional and psychological components alongside the physical ones produces better outcomes. Major medical organizations recommend a multidisciplinary approach for persistent sexual pain, involving not just a gynecologist or urologist but potentially a pelvic floor therapist, psychologist, or sexual counselor.
What Treatment Looks Like
Treatment depends entirely on the cause, which is why getting a clear diagnosis matters more than trying remedies at random. For infections, the fix is often straightforward. For hormonal changes, topical treatments applied directly to the vaginal tissue can make a meaningful difference. For skin conditions like lichen sclerosus, managing inflammation early prevents the scarring that makes things worse over time.
For pelvic floor dysfunction, physical therapy is one of the most effective interventions. A pelvic floor physical therapist uses internal manual techniques, biofeedback, and sometimes vaginal dilators to help the muscles learn to relax. The therapy improves muscle awareness, increases vaginal elasticity, and normalizes the resting state of the muscles. In one study, patients saw significant improvement in pain scores after five weeks of twice-weekly treatment, with benefits lasting over four months. Internal manual techniques were the most effective approach, followed by patient education and at-home exercises with dilators.
For persistent vulvar pain specifically, the American College of Obstetricians and Gynecologists recommends an individualized approach that addresses both physical and emotional factors. Topical medications in ointment form (rather than creams, which contain more preservatives and tend to burn on application) are often a first step. Physical therapy and biofeedback are recommended alongside any medication. The emphasis is on realistic treatment goals and a clear understanding of the diagnosis, because knowing what’s happening in your body changes how you experience and respond to the pain.
The most important thing to understand is that pain during sex is not something you should push through or accept as normal. It has a cause, and in the vast majority of cases, that cause is treatable.
