Hi i am a 30 year old female. Married now for about 8 years, these past 3 years sex has become terribly painful, As streight after penetration the vaginal enterance swells and penetration is so painful. I have used all different types of lubricants still same result. After sex when i clean up i usually have blood and it becomes very uncomfortable to sit. Gps did all the std etc test and its all clear not even thrush... could anyone help me find out what is wrong?
