Marder Appologies if this is may give too much info but not sure how else to explain it lol
With the fs belts they use wire rope that runs through tubes on the shield and the tubes in the side of the anal ring. Without the anal ring I just have a silicone tube over the cables so they don't pinch and that sits between my but cheeks.
So when I sit on the toilet I can just pull the cable to the side and do my business. We are not like europe and bidets and the like are not standard so if the cable gets messy I use a wetwipe to clean it which is easy enough. With the ring is its not perfectly aligned then it get messy and no easy to clean without belt removal. Its is personal preference really
