I was just told i have a friable cervix at my yearly appointment. is this what has been causing sex to be painful for me? does friable cervix go away?

Unlikely: Mots commonly when a cervix is described as "friable" it is related to some external process that is causing this to occur. Nonetheless, a "friable" cervix is a description of what the doctor observes and NOT a diagnosis. If you are having painful intercourse, further evaluation is required. Some infections can cause the cervix to become "friable," however a "friable" cervix could also be normal.
