Causes for pain during sex include:
* Intercourse too soon after surgery or child birth
* Vaginal dryness or inadequate lubrication (for example, from insufficient foreplay)
* Menopause (vaginal lining loses its normal moisture and becomes dry)
* Vaginal infection
* Reaction to the latex of a diaphragm or condom
* Prostatitis -- inflammation of the prostate
* Genital irritation from soaps, detergents, douches, or feminine hygiene products
* Herpes sores, genital warts, or other sexually transmitted diseases
* Urinary tract infections
* Endometriosis
* Vaginismus -- involuntary contraction of the vaginal muscles; this may be a result of ongoing painful intercourse as well as a cause
* Ill fitting diaphragm
* Sexual abuse or rape
* Hemorrhoids
* Certain medications
It may be best to see the doctor together with your partner. A physical examination may include a pelvic examination (for women), a prostate examination (for men), and a rectal examination. If a physical problem is suspected, appropriate tests will be ordered and the treatment can proceed from there.
