Pain during sex is one of the most common reasons people see a gynecologist and one of the least often mentioned out loud. It is also one of the few problems where a single detail does most of the diagnostic work.
Pain during sex is common, and the reasons for it are mostly ordinary and treatable. What makes it drag on is rarely the medicine. It is that the first sentence is hard to say, and harder in a second language, so people wait — and in the meantime the body starts bracing in anticipation, which is its own problem on top of the original one.
The useful thing to know before the appointment is that one detail does most of the work.
The first question: entrance, or deep inside
Almost every consultation about this starts here, because the answer splits the possible causes into two mostly separate lists. It is worth deciding which one describes you before you go in — or saying honestly that it is both, which is also a real answer.
Pain at the entrance points towards the vulva, the vaginal opening, or the pelvic floor muscles.
Pain deep inside, often felt lower in the abdomen and sometimes only in certain positions, points towards the pelvic organs — the uterus, ovaries, and the tissue around them.
Pain at the entrance
Four causes account for most of it.
Dryness. Less lubrication means friction, and friction means pain. It is not only a menopause question: some hormonal contraceptives reduce lubrication, so does breastfeeding, and so does simply not being relaxed. This is the most common cause and the most easily addressed.
Infection. A yeast infection or bacterial vaginosis can make the tissue sore and inflamed enough that entry hurts. Usually there are other signs — itching, a change in discharge — and treatment is short.
A skin condition. The vulva can develop dermatitis or other skin conditions like any other skin, and they are often missed because people do not think to look. These respond to treatment but need to be identified first.
Pelvic floor muscle tightening. The muscles around the vaginal opening can tighten involuntarily — not a decision, and not something you can simply relax out of. When it is the main problem this is called vaginismus, and it deserves its own paragraph below.
Pain deep inside
Deep pain, particularly if it is position-dependent or worse around your period, more often reflects something in the pelvis itself.
Endometriosis is one of the more common explanations and one of the most frequently missed, partly because it is often invisible on a scan. Adenomyosis can do the same. An ovarian cyst, or a fibroid sitting in a particular spot, can make certain positions painful and others fine. Pelvic inflammatory disease — infection that has moved upward — is less common but matters, because it is treated urgently rather than electively.
If the pain is deep and cyclical, mention the timing. The relationship to your period is one of the strongest clues available.
Vaginismus, briefly
When the pelvic floor muscles tighten on approach, entry can become painful or impossible. This is a reflex, not a psychological failing and not something you are doing. It often begins after something that genuinely did hurt — an infection, a difficult examination, a first experience that went badly — and then continues on its own after the original cause has resolved.
It responds well to graded work with the muscles: pelvic floor physiotherapy and, commonly, a set of dilators used at your own pace at home. Availability of dedicated pelvic floor physiotherapy varies by clinic in Korea, so it is a reasonable thing to ask about when you book rather than assume.
Surgery is almost never the answer
This is worth stating plainly, because the fear of it is part of what keeps people from coming in.
Painful sex is not a surgical problem. Surgery enters the conversation only when the underlying cause is structural and would be treated on its own merits — endometriosis or a cyst, for instance — and even then it sits alongside medical options rather than ahead of them. The far more common outcome of a first appointment is a topical treatment, a short course of medication, a change to contraception, or a referral for muscle work.
What the appointment involves
The history comes first and carries most of the weight: when it started, entrance or deep, every time or sometimes, position-dependent or not, whether it has changed. Vague answers are fine — the doctor will narrow it with questions.
An examination follows, and it is usually brief. If infection is a possibility, a swab. If the pain is deep, an ultrasound to look at the uterus and ovaries — and pain in a specific spot during that scan is itself useful information, so it is worth saying rather than enduring.
You do not have to agree to an internal examination on the day. If entry is painful, saying so changes how the examination is done, and sometimes defers it to a second visit once treatment has started.
When to be seen sooner
Most of this can wait for a routine appointment. These should not:
- Pelvic pain with a fever
- New, severe pain rather than the familiar pattern
- Bleeding after sex, even a small amount
- Pain alongside an abnormal discharge or a strong odour
Saying it in Korean
If you do end up in a clinic without English support, these four sentences cover the essentials:
| Korean | Meaning |
|---|---|
| 성관계 시 통증이 있어요 | It hurts during sex |
| 들어갈 때 아파요 | It hurts on entry |
| 깊은 곳이 아파요 | The pain is deep inside |
| 관계 후 출혈이 있어요 | I bleed after sex |

Having the conversation in English
This is a problem made almost entirely of description — where, when, how it started, what makes it worse, what you have already tried. Precision is what shortens the path to an answer, and precision is the first thing lost when you are translating in your head while saying something you already find difficult.
At Yoonho the consultation is handled in English, so the description can be yours rather than an approximation of it. See our clinics, read our guide to seeing a gynecologist in Korea, or message us on WhatsApp or KakaoTalk.

Common questions
Is pain during sex something a doctor can actually treat?
In most cases yes, and often straightforwardly. The common causes — dryness, infection, a skin condition, or pelvic floor muscles that have learned to tighten — all respond to treatment. The part that tends to delay things is not the treatment but the first sentence.
Will I need surgery?
Very rarely. Surgery is not a treatment for painful sex in itself. It comes up only when the cause is a structural one that would be treated anyway, such as endometriosis or a cyst, and even then it is one option among several rather than a starting point.
What is the difference between pain at the entrance and deep pain?
Entrance pain usually comes from the vulva, the vaginal opening or the pelvic floor muscles — dryness, infection, skin conditions, or involuntary muscle tightening. Deep pain is more often from the pelvic organs, including endometriosis, adenomyosis, a cyst, or the position of a fibroid. Telling the doctor which one you have narrows the list immediately.
I bleed a little after sex. Is that related?
It may be, and it is worth having checked on its own rather than waiting. Bleeding after sex often comes from the cervix, and the examination that looks at that is quick. It is one of the few symptoms here that should not simply be watched.
Can I have this conversation in English in Seoul?
Yes. This is a description-heavy problem — where, when, how it started, what makes it worse — and precision is what shortens the path to an answer. A clinic set up for international patients means you can give that description without translating as you go.
