Endometriosis can cause severe abdominal pain during or after sex and having pains especially in the pelvic area during sexual intercourse is a common symptom because penetration during sex can stretch and pull the endometrial tissue. It would be great to also know that not all women who have endometriosis experience pain during sexual intercourse however the pain varies from person to person and the type of intercourse engaged in. It is advisable that persons affected communicate genuinely and openly with their partners to foster an atmosphere of understanding between both parties as dealing with painful sex can be challenging and emotionally frustrating.
