Bumped the cervix: Occasionally, with sexual intercourse, the male's penis may bump against the cervix of the woman. This can cause a sharp pain, and, sometimes, some aching later. A little spotting is not unusual. You may need to experiment with different positions and angles to prevent him from hitting against your cervix if this is uncomfortable.
