Endometriosis and sex during a period

Endometriosis can affect tissue around the vagina, womb, ovaries, bowel, or pelvic lining. During a period, cramps and pelvic sensitivity may already be present, and deeper penetration can increase discomfort. Pain may be deep or near the vaginal opening and may continue after sex. Bleeding during a period is not itself a reason to avoid intimacy, but pain is a reason to pause and take it seriously. Other conditions can also cause [Pain During Sex](/symptoms/pain-during-sex/).

Talk openly with your partner, agree that either person can stop, and consider non-penetrative intimacy. If you choose penetration, go slowly, use lubricant, try positions that control depth, and stop before pain escalates. Heat and suitable pain relief may help cramps. Keep a record of timing, depth, and symptoms, then discuss persistent pain with a clinician. [Endometriosis](/conditions/endometriosis/) treatment can be tailored to your symptoms and plans.

Arrange an assessment when pain during or after sex keeps recurring, affects relationships, or occurs with painful periods, pelvic pain, unusual discharge, or trouble getting pregnant. Seek urgent care for sudden severe pain, fainting, fever, or heavy bleeding.
