Pain during sex is common, it is not in your head, and it almost always has a reason that can be treated.

Pain during or after sex (doctors call it dyspareunia) is something many women experience, yet rarely raise. It deserves to be treated as what it is: a medical symptom with real, findable causes — not something to endure quietly or feel embarrassed about. In most cases, once the cause is identified, it can be eased.

The common medical reasons

Pain during sex can come from several places:

  • Vaginal dryness, often from lower oestrogen (see vaginal dryness and discomfort)
  • Infections of the vagina or urinary tract
  • Conditions like endometriosis or fibroids, which can cause deeper pain
  • Tight or tense pelvic-floor muscles, sometimes linked to past pain or anxiety
  • Skin conditions affecting the intimate area
  • After childbirth, while tissues heal or while breastfeeding
  • Pelvic infections or other gynaecological conditions

The type of pain — at the entrance versus deep inside, occasional versus constant — gives a doctor strong clues about which of these is responsible.

Why it shouldn't be ignored

Two reasons. First, pain teaches the body to avoid — repeated discomfort can lower desire and create tension, so a physical problem grows into an emotional and relationship one (see low libido in women). Second, some causes — infections, endometriosis, pelvic conditions — are better treated early. Persistent pain is the body asking for attention.

When to get checked

See a doctor if pain during sex is:

  • Repeated or severe
  • Coming with bleeding, unusual discharge, or pelvic pain
  • Present outside of sex too
  • Affecting your wellbeing or relationship

A one-off discomfort can have a simple explanation. A pattern of pain should always be checked.

What a doctor does

A doctor asks about the type and timing of the pain, checks for infections and gynaecological causes, and identifies what is treatable. This is routine, private work for a gynaecologist — and naming the cause is usually the start of real relief.

Pain is a message, not a flaw. Bringing it to a doctor is how it gets answered.
