Yes, I just wedge it between my cheeks and it stays there for the most part. Sometimes it comes out and I just wedge it back in. I spoke with the nurse yesterday and she said that I could still use the gauze if the stitches were pinching me (11 days post op) . And, that if I wanted to stop using the gauze, that would be fine. And I could apply A&D ointment to the stitches to soften them up a bit. I have a follow up appointment in a couple of weeks where they will probably remove any stitches that are left.
When I pee, I just remove it and put it back. I'm not sure about the fistual gauze, but I imagine keeping any wound protected and dry is important.
Glad you are doing better!
