@flind when I went to a physical therapist for urinary incontinence she suggested that the rectocele could be causing what I felt was fecal incontinence and told me about putting a sterile glove on and pushing it out manually.

This does seem to be a problem that doctors are loathe to bring up. I hope your appointment goes well and presents some solution. I hope too that you will post about it. I am very interested.
