Why Does Sex Become Painful? Causes & Treatment Guide

Pain during sex is one of those experiences that far too many people in India simply endure in silence. Women are told it's normal especially the first time, after childbirth, or as they get older. Men are told it shouldn't be happening at all which makes them less likely to mention it to anyone. And both end up carrying a very real medical problem without ever receiving proper diagnosis or treatment.

Around 75% of women experience painful sex at some point in their lives, according to the American College of Obstetricians and Gynecologists. Dyspareunia is more common in women than men but both can experience it, and it always has an identifiable cause.

Many people do not seek help because they feel embarrassed or think it is normal. But painful sex is not a normal part of life and it is not something to simply accept and endure. 

The medical term for painful intercourse is dyspareunia defined as persistent or recurring pain before, during, or after sexual activity. It is a treatable condition. And understanding what is causing it is the essential first step toward resolving it.

What Is Dyspareunia?

Dyspareunia is the medical term for persistent or recurring genital pain experienced before, during, or after sexual intercourse. It affects both men and women, has many possible physical and psychological causes, and is always worth investigating because it almost always has an identifiable and treatable root cause.

There are two broad types based on where the pain is felt:

• Superficial dyspareunia - Pain at the vaginal opening at the start of penetration; most commonly caused by dryness, infections, skin conditions, or vaginismus

• Deep dyspareunia - Pain felt deeper in the pelvis or abdomen during or after penetration; more commonly associated with conditions like endometriosis, fibroids, or pelvic inflammatory disease

Both types are real medical concerns. Neither should be dismissed or endured without investigation.

Why Does Sex Become Painful in Women?

1. Vaginal Dryness

Vaginal dryness from menopause, childbirth, breastfeeding, medications, or too little arousal before intercourse is one of the most common causes of painful sex in women.

Without sufficient lubrication, friction during intercourse causes pain, irritation, and sometimes small tears in vaginal tissue. This is not a sign of not being attracted to your partner it is a physiological issue with specific, addressable causes:

• Menopause - Falling oestrogen levels thin and dry the vaginal walls

• Post-partum and breastfeeding - Hormonal changes temporarily reduce natural lubrication

• Medications - Antihistamines, antidepressants, and hormonal contraceptives can all reduce lubrication

• Insufficient foreplay - Inadequate arousal time before penetration is one of the most easily corrected causes

2. Vaginismus

Vaginismus refers to involuntary muscle spasms in the pelvic floor that make intercourse uncomfortable or completely impossible, one of the most common causes of painful sex.

The muscle contraction is not consciously chosen; it happens automatically, often driven by fear, anxiety, past painful experiences, or deeply held negative beliefs about sex rooted in cultural conditioning.

Vaginismus is extremely common particularly in India where women receive little or no preparation for the physical realities of intimacy and it is highly treatable with the right specialist support. Read our complete vaginismus guide →

3. Infections and Inflammation

Infections such as yeast infections, urinary tract infections (UTIs), and sexually transmitted infections can cause inflammation and pain during sex.

Common infections causing painful sex include:

• Yeast infections (thrush) - Cause itching, burning, and soreness that makes sex uncomfortable

• Bacterial vaginosis - Disruption of normal vaginal flora causing irritation

• UTIs - Bladder and urethral inflammation causing burning during and after sex

• Pelvic inflammatory disease (PID) - PID is an internal infection that has passed into the uterus and surrounding organs, often causing deep pelvic pain during sex. It is important to treat it with antibiotics to prevent complications and in most cases the infection is passed on through sex. Testing for chlamydia, gonorrhoea, and syphilis is an important part of assessing painful sex when an STI is possible.

4. Endometriosis

Endometriosis where tissue similar to the uterine lining grows outside the uterus is one of the most significant and frequently missed causes of deep, persistent painful sex in women.

Deep pain during sex deep dyspareunia is pain felt deeper inside the pelvis or abdomen during penetration. It is more commonly associated with conditions affecting the internal pelvic organs, including endometriosis and uterine fibroids.

Endometriosis affects an estimated 1 in 10 women of reproductive age yet average diagnosis time in India remains extremely long because symptoms are normalised and dismissed. Deep pain during sex, particularly around menstruation, is one of its most consistent signals.

5. Hormonal Changes 

Many women notice significant changes in their vagina and genital area after menopause and during perimenopause, when hormone levels fluctuate. Falling oestrogen causes vaginal atrophy thinning, drying, and inflammation of vaginal tissue making intercourse increasingly uncomfortable or painful.

This is one of the most common and most undertreated causes of painful sex in Indian women because menopause and its effects are rarely discussed openly. It is very effectively managed with topical oestrogen, lubricants, and vaginal moisturisers under medical supervision.

6. Skin Conditions Affecting the Vulva

Skin disorders that cause ulcers, cracks, itching, or burning in the vulvar area can make any contact or penetration painful.

Conditions like lichen sclerosus, vulvodynia (chronic vulvar pain without an identifiable cause), and contact dermatitis (reaction to soaps, detergents, or latex) all produce pain at the vulvar surface that makes sex uncomfortable.

These conditions require a specific dermatological or gynaecological assessment and respond well to targeted treatment once properly identified.

7. Structural and Post-Surgical Causes

Injury or trauma from childbirth, an accident, an episiotomy, a hysterectomy, or pelvic surgery can cause scar tissue that makes intercourse painful.

Episiotomy scars, caesarean section scar tissue, and post-hysterectomy changes in vaginal length and flexibility are all real causes of painful sex that deserve proper assessment and targeted treatment.

8. Psychological and Emotional Causes

Factors triggering dyspareunia include relationship problems, stress that leads to tightened pelvic floor muscles, and fear, shame, or guilt related to sex as well as a history of sexual abuse or rape.

Dyspareunia can become a vicious cycle. Pain leads to nervousness about having sex, and nervousness leads to dryness, which may itself be a cause of further pain. It is not uncommon for dyspareunia to remain after the physical cause has been treated, particularly if things have been left untreated for a while.

This cycle is why psychological support alongside physical treatment is often essential for complete resolution. Sex therapy and sensate focus therapy directly address the anxiety and avoidance patterns that sustain painful sex long after physical causes have been addressed.

Why Does Sex Become Painful in Men? 

Painful sex in men is less commonly discussed but it is a real concern with specific, treatable causes.

In males, painful intercourse is almost always related to an underlying medical condition. Men can feel pain on the head of their penis, on the shaft, in their testicles, or in their pelvis during or after sexual activity.

Common causes of painful sex in men include:

• Phimosis - A tight foreskin that cannot retract fully during erection, causing pain and discomfort during sex

• Prostatitis - Inflammation of the prostate gland causing deep pelvic pain during or after ejaculation; one of the most common causes of painful sex in men under 50

• STIs - Chlamydia, gonorrhoea, and herpes can all cause pain, burning, and discomfort during sexual activity

• Peyronie's disease - Development of scar tissue inside the penis causing painful erections and curved, painful intercourse

• Skin conditions - Balanitis (inflammation of the foreskin or glans) causes soreness and pain during sex

• Urinary tract infections - Burning and discomfort during sex related to bladder or urethral inflammation

• Psychological factors - Performance anxiety causing pelvic floor tension that creates discomfort during sex

Symptoms of Painful Sex

Dyspareunia is a common condition that can have significant emotional and psychological effects. In addition to the physical pain, couples may experience a loss of intimacy or strain in their relationships.

Symptoms worth taking seriously include:

Physical symptoms:

• Pain at the vaginal opening at the start of penetration

• Deep pelvic or abdominal pain during or after intercourse

• Burning, stinging, or aching during sexual activity

• Pain that persists for hours after sex has ended

• Throbbing or cramping during or after intercourse

• Pain in specific positions but not others

Emotional and relational consequences:

• Fear or dread before anticipated sexual activity

• Avoidance of intimacy due to expectation of pain

• Guilt  feeling that you are "failing" your partner

• Relationship strain as intimacy reduces or stops

• Reduced self-confidence and body image concerns

If these symptoms have been present for more than a few weeks and are recurring they deserve proper professional attention.

How Is Painful Sex Diagnosed?

Several tests help doctors identify and diagnose dyspareunia. Your doctor will start by creating a complete medical and sexual history asking about when the pain occurs, where it is felt, how long it has been happening, and any related symptoms.

At Happy Waves, our approach to diagnosing painful sex includes:

Thorough history - Understanding when the pain started, what triggers it, where exactly it is felt, and what makes it better or worse

Physical assessment - Where clinically indicated; conducted with full patient consent and at a pace that feels safe and comfortable

Investigation guidance - Blood tests (hormonal panel, STI screening), swabs where infection is suspected, and if deep pelvic causes like endometriosis are suspected appropriate referral for imaging or specialist investigation

Psychological assessment Evaluating the role of anxiety, relationship dynamics, past experiences, and pelvic floor muscle tension

According to Dr. Shakeeba Naaz, a trusted sexologist at Happy Waves Mumbai with over 12 years of experience in female sexual health, painful sex is one of the most consistently undertreated conditions in India because both patients and general physicians normalise it. The first step toward ending that pain is simply recognising that it is a medical condition not a personal failing or an inevitable reality and getting a proper assessment.

Treatment for Painful Sex

Treatment options for dyspareunia usually depend on the cause which is why identifying the underlying reason is so important before beginning any treatment.

Medical Treatments

• Topical oestrogen - For menopausal vaginal dryness; highly effective and available in cream, ring, or suppository form

• Lubricants and vaginal moisturisers - Immediate relief for dryness-related pain during sex

• Antibiotics - For bacterial infections including PID and STIs

• Antifungal treatment - For yeast infections causing vulvar irritation

• Hormonal management - Addressing underlying hormonal imbalances contributing to dryness or atrophy

• Topical anaesthetics - For vulvodynia and surface pain conditions

Physiotherapy and Pelvic Floor Work

For vaginismus and pelvic floor dysfunction which underlie a significant proportion of painful sex cases in India pelvic floor physiotherapy is a cornerstone of treatment.

This involves:

• Learning to identify and release involuntary muscle tension

• Progressive relaxation exercises specific to the pelvic floor

• Gradual, self-directed dilator therapy to desensitise the tissue response to penetration

• Breathing techniques that activate the parasympathetic nervous system and reduce automatic muscle contraction

Sex Therapy and Psychological Support

Because psychogenic dyspareunia is often connected to a lack of arousal, anxiety, or avoidance patterns, sex therapy procedures specifically designed to rebuild comfort with intimacy are commonly and effectively used.

Sex therapy addresses:

• The fear-pain cycle that sustains dyspareunia long after physical causes are treated

• Performance anxiety and anticipatory fear of pain

• Partner communication around intimacy and comfort

• Rebuilding positive associations with physical closeness through sensate focus therapy

Treating the Underlying Condition

For conditions like endometriosis, fibroids, or Peyronie's disease treating the underlying medical condition is the primary pathway to pain relief. This may involve specialist gynaecological or urological assessment and treatment alongside sexological support.

Relationship Support

Relationship problems and communication difficulties are recognised triggers of dyspareunia. When painful sex has created distance, avoidance, or unspoken tension between partners, couples-based support through relationship counselling is often an essential part of the treatment picture.

When to Seek Help And Where to Find It

• Pain during sex has occurred on more than a few occasions

• It is causing you to avoid intimacy entirely

• You have associated symptoms unusual discharge, bleeding, pelvic pain outside of sex

• Your partner's distress about the situation is creating relationship tension

• You are post-menopausal and experiencing increasing discomfort with intercourse

• You are post-partum and pain has persisted beyond six weeks
