Endometriosis affects roughly one in ten people with a uterus, and somewhere between half and two-thirds of those will experience pain during or after sex. It's the symptom most often dismissed and least often raised in clinic, partly because most people don't realise the pain has a specific anatomical explanation and a real list of things that help. This is what's actually happening, and what to do about it.
Why endometriosis specifically hurts during sex
Endometriosis is the growth of tissue similar to the uterine lining outside the uterus — typically on the ovaries, fallopian tubes, the back of the uterus, and the deeper pelvic ligaments. The implants behave like uterine tissue: they bleed cyclically, scar, and create adhesions that bind organs to each other.
That biology produces a particular pain pattern with sex:
- Deep dyspareunia. Pain on deep penetration, often described as sharp, stabbing, or "hitting something." Caused when the penis (or toy) presses against implants, scarred ligaments, or tethered organs.
- Lingering ache afterwards. Pain that continues for hours or days post-sex. Inflammation around touched implants doesn't subside as fast as ordinary muscle soreness.
- Pelvic floor guarding. Months or years of painful sex teach the pelvic floor to clench in anticipation. That hypertonic floor then causes its own pain — at the entrance and during penetration — independent of the underlying endometriosis.
- Cyclical worsening. Sex pain often worsens around your period and ovulation, when implants are most active.
The pain is real and located. It's not in your head, and it's not "you need to relax more." The relax-more advice usually comes from people who don't understand the mechanism.
Things that genuinely help — in approximate order of accessibility
1. Position changes
The first and cheapest intervention. Deep dyspareunia is angle-dependent. Positions that limit depth or change the trajectory away from posterior implants tend to help:
- Spooning / side-lying. Naturally limits depth.
- Woman on top. You control depth and angle.
- Modified missionary with hips lower, partner more aligned with vaginal axis rather than aimed posteriorly.
- Avoid deep doggy-style and any position where your partner is angled steeply downward into the posterior fornix — that's exactly where most painful implants sit.
2. A penetration limiter
Soft silicone "bumper" rings (the brand Ohnut is the best known, with copies available locally now) sit at the base of a partner's penis and prevent deep impact. Worn singly or stacked. They sound like a small thing; for many people with deep dyspareunia they are the single most useful purchase in their bedroom.
3. Treat the pelvic floor
Pelvic floor physiotherapy with a clinician trained in pain conditions is one of the highest-value interventions, and it's underused. Hypertonic pelvic floor — overactive, clenched musculature — is co-present in most people with chronic deep dyspareunia. Treatment involves down-training (releasing) rather than strengthening: breathwork, internal soft tissue work, sometimes wand or trainer use at home. Six to twelve sessions is typical.
4. Lubrication and warm-up
Pain compresses arousal. Compressed arousal reduces natural lubrication. Reduced lubrication adds friction pain to the pre-existing deep pain. Use a high-quality silicone-based lubricant generously and stretch warm-up time. This won't fix endometriosis but it removes one variable from the pain stack.
5. Hormonal management
Continuous combined oral contraceptives (taking the pill back-to-back without a break), the hormonal IUD, or progestin-only options like dienogest can suppress endometrial activity and reduce both period pain and sex pain over time. Not a quick fix — meaningful improvement often takes three to six months — but for many people it's a substantial reduction. GnRH antagonists (newer agents like elagolix, increasingly available) are an option for severe cases when first-line hormones fail.
Hormonal management has trade-offs (sometimes dropping libido, sometimes mood effects). The conversation with your gynae is worth having with full information about both your sex pain and your sex drive — those are different issues that the same medication can change in different directions.
6. Pain medication, used strategically
Anti-inflammatories (ibuprofen, naproxen) taken an hour before sex can dampen the inflammatory cascade triggered by contact with implants. Useful as a tool, not a long-term-only strategy.
7. Surgery — when and when not
For severe or treatment-resistant cases, laparoscopic excision of endometriosis by a specialist surgeon can substantially reduce sex pain. Two important caveats:
- Excision, not ablation. Excision (cutting out the implants) has better outcomes than ablation (burning the surface) for deep disease. Ask your surgeon which they do.
- Surgeon experience matters enormously. Endometriosis surgery is technically demanding. Specialists in major centres operating in dedicated endometriosis MDTs (multidisciplinary teams) have substantially better outcomes than generalist gynaecologists doing occasional cases. Ask: how many endometriosis cases do you do per year? Do you operate in a dedicated MDT? What's your re-operation rate?
Surgery isn't always the answer — for superficial disease, hormones and pelvic floor work often do enough. For deep infiltrating endometriosis, particularly when bowel or bladder are involved, surgery becomes more clearly indicated.
Sex other than penetrative
This is often the part nobody mentions in the clinic. While you're working through treatment — which may take months or years to fully optimise — your sex life doesn't have to pause. Most people with endometriosis find that:
- External clitoral stimulation, manual or with a vibrator, is unaffected.
- Oral sex (giving and receiving) is generally fine.
- Mutual masturbation works.
- Anal play can be more painful with bowel-involved endometriosis but is fine for many.
- Outercourse, edging, dry humping — all available.
Decentring penetration — making it one option rather than the goal — is one of the gentler reframes that often improves the whole sexual dynamic regardless of where you are with treatment.
The conversation with your partner
Endometriosis sex pain is rarely just a medical problem. It changes the way couples approach intimacy, often without an explicit conversation. Common patterns: the affected partner starts initiating less to avoid the pain, the other partner reads that as rejection, both stop talking about sex altogether, the bedroom becomes a quiet minefield.
A useful conversation, not at bedtime:
"My pain isn't about you and it isn't about us. Here's what's actually happening physically. Here's what helps and what makes it worse. I want to keep our sex life — not in the same shape we had before, but in a shape that works while I'm sorting this out. Can we plan together?"
Most partners are relieved to be told what's going on. The not-knowing is harder than the knowing.
The diagnostic delay nobody warns you about
The average time from first symptoms to endometriosis diagnosis is around 7-10 years globally, and likely longer in South Africa. The reasons are infuriating: period pain gets normalised, sex pain gets dismissed, and definitive diagnosis still typically requires laparoscopy. If you've been told your symptoms are "just bad periods" and you're not improving on first-line management, ask for a referral to a specialist with endometriosis experience. Insist if needed.
See a clinician if
- Sex has become consistently painful and isn't improving with position changes and lubrication.
- Period pain interferes with daily life, school, or work.
- You have heavy periods, mid-cycle bleeding, or pain with bowel movements during your period.
- You've been trying to conceive without success and have any of the above symptoms — endometriosis is a major contributor to infertility.
The bottom line
Endometriosis sex pain has anatomy, mechanism, and treatments. It is not a relationship problem and it is not a tolerance problem. A combination of position changes, a depth limiter, pelvic floor work, hormonal suppression, and — where indicated — specialist surgery improves outcomes for most people. The sooner the diagnosis lands and a real plan is in place, the shorter the wait between now and a sex life that doesn't hurt.
