Perineum bleeding after sex: what to know

Blood noticed after sex may arise from a small split in the perineal skin, the vaginal wall or the cervix. Friction, insufficient lubrication, a new sexual activity, inflammation and vaginal dryness can make delicate tissue bleed. Infection such as [Chlamydia](/conditions/chlamydia/) may cause bleeding alongside discharge, pelvic pain or burning when urinating. Cervical changes, including [Cervical Dysplasia](/conditions/cervical-dysplasia/), can also bleed with contact; less commonly, cancer of the cervix or vagina is involved. A clinician can identify the source rather than relying on the colour or amount of blood alone.

Stop sex if bleeding or pain continues. Use a pad to observe whether bleeding settles, and avoid tampons until the source is clear. Do not douche or use fragranced products. Arrange an appointment if this has happened more than once, occurs after menopause, follows a new partner, or comes with discharge, pelvic pain, sores or urinary symptoms. The visit may include an examination, infection testing and cervical screening when appropriate.

Treatment depends on the cause. Dry or fragile tissue may need a tailored plan, while infection requires specific treatment and partner advice. [Genitourinary Syndrome of Menopause](/conditions/genitourinary-syndrome-of-menopause/) is one possible explanation for dryness and contact bleeding. A [Cone Biopsy](/treatments/gynaecological-surgery/cone-biopsy/) may be discussed only when cervical testing shows a reason to examine or remove abnormal tissue.

Seek urgent care for heavy bleeding, faintness, severe or one-sided pelvic pain, shoulder-tip pain, fever, or a possible pregnancy with pain or bleeding. Prompt assessment is needed for bleeding that keeps returning, happens after menopause, or occurs with a visible vaginal sore or unexplained weight loss. These features need evaluation even when the bleeding is light.

Ask where the blood is coming from, whether you need infection testing or cervical screening, and whether dryness or a medication could contribute. Ask which symptoms should prompt urgent review and when sex is safe again.
