Endometriosis and sex: understanding deep pain and finding comfort

Endometriosis is one of the most common causes of deep pain during sex: around half of people with the condition experience it. The pain usually comes from deep penetration pressing on tender tissue in the pelvis, and it is real, physical and not something to push through. Medical treatment, pelvic floor physical therapy, adapted positions, depth limiters and good communication can make intimacy comfortable again for many people.

What endometriosis is

Endometriosis is a long-term condition in which tissue similar to the lining of the uterus grows outside the uterus, most often on the ovaries, the lining of the pelvis, the ligaments behind the uterus and sometimes the bowel or bladder. This tissue responds to hormonal cycles and causes inflammation, pain and scar tissue (adhesions).

The NHS estimates that around one in ten women of reproductive age has endometriosis. Diagnosis often takes years, partly because painful periods and painful sex are too often treated as normal.

Common symptoms include:

• Painful periods that interfere with daily life
• Pelvic pain outside of periods
• Deep pain during or after sex
• Pain with bowel movements or urination during periods
• Fatigue
• Difficulty getting pregnant

Why endometriosis causes painful sex

The pain is usually deep rather than at the entrance. It tends to occur with deeper thrusting or in certain positions, and may linger for hours or even a day afterward.

Several mechanisms play a role:

• Tender lesions: endometriosis on the uterosacral ligaments, behind the cervix or between the vagina and rectum is pressed or stretched during deep penetration.
• Adhesions: scar tissue can reduce how freely pelvic organs move.
• Inflammation: affected areas are often more sensitive around periods.
• Pelvic floor tension: chronic pain leads many people to brace their pelvic floor, which adds muscle pain and can also cause entry pain.
• Central sensitization: long-standing pain can make the nervous system more reactive, so that even light pressure hurts more.

Many people with endometriosis have both deep and entry pain, which is why a full assessment matters. See our overview of dyspareunia for the difference.

Getting a diagnosis

Start with a GP or gynecologist, and describe the pattern: where it hurts, when in your cycle, and whether sex, periods and bowel movements are affected. Assessment may include a pelvic exam and an ultrasound or MRI. Laparoscopy, keyhole surgery, can confirm the diagnosis and treat lesions at the same time. Keeping a short symptom diary can help a clinician see the pattern.

Treatment options

Hormonal treatment

Hormonal medicines, such as the combined pill, progestogen-only options or a hormonal IUD, can reduce or stop periods and slow the activity of endometriosis tissue. For many people this reduces pain, including during sex. The right option depends on your symptoms, plans for pregnancy and medical history.

Surgery

Laparoscopic removal of endometriosis can reduce pain, especially when deep disease is present. Specialist endometriosis centers are recommended for complex cases. Surgery helps many people, but pain can persist or return, so it is often combined with other care.

Pelvic floor physical therapy

Pelvic floor tension is very common in endometriosis. A pelvic floor physical therapist can help release overactive muscles through relaxation training, breathing, manual therapy and exercises such as reverse kegels. This often makes a noticeable difference to pain during sex, alongside medical treatment.

Pain management

Pain specialists and psychologists can help with central sensitization and the stress that comes with chronic pain. Approaches like cognitive behavioral therapy and pain education have a place alongside physical treatment.

Practical ways to make sex more comfortable

Control depth

Because the pain is mostly deep, limiting depth is the most effective adjustment. Options include positions that naturally reduce depth and wearable depth-limiting rings. A pilot randomized trial at a Canadian endometriosis center found that couples using a set of soft, stackable depth-limiting rings reported less deep pain than a comparison group, and both partners found it acceptable.

Choose positions that give control

• Side-lying or spooning, which limits depth
• On top, leaning forward, so you control angle and speed
• Legs closer together, which shortens the reachable depth

Time it with your cycle

Many people find sex more comfortable at certain points in their cycle and more painful just before or during their period. Planning intimacy around this is a reasonable choice, not a failure.

Use lube and take time

Hormonal treatments can cause dryness. A good water-based lube and plenty of arousal time reduce friction and tension.

Redefine sex

Intimacy does not have to center on penetration. Touch, oral sex, mutual masturbation and approaches like sensate focus keep closeness alive on painful days.

Talking with a partner

Partners often feel helpless or worry about causing pain. Explaining that the pain is physical, that it depends on depth and timing, and what helps, turns it into a shared problem with practical answers. Agree on a signal to slow down or stop. Our guide to talking about pain with a partner has more on starting this conversation.

When to seek help

See a GP or gynecologist if you have deep pain during sex, painful periods that affect daily life, or pelvic pain outside of sex. If you already have a diagnosis and sex is still painful despite treatment, ask about pelvic floor physical therapy and referral to a specialist endometriosis or pelvic pain service. Pain during sex with endometriosis is common, but it is not something you simply have to accept.
