In women, the pain may be felt deep in the pelvic region, in the vagina itself, or superficially. The exact number of women experiencing dyspareunia is unknown but some studies suggest it is common. You indicated that there was bleeding involved so that suggests a physical problem. These range from infections to side effects of certain medications. Although you saw a doctor, you need to ask yourself how candid you were.
Most people tend to minimize when they talk to their doctor.
Talk to her again or see a gynecologist and be very frank about this problem. It is important to give as much information as possible concerning when the pain begins, exactly what you and he were doing, to assist in identifying the problem. If you have been absolutely frank and there is nothing physical after checking again, you need to see a counselor who can help with this sort of problem. Ask the doctor for a referral to a specialist or talk to a counselor at the Counseling Center who can help refer you to a specialist. Whatever else you do, you need to think about this relationship.
