Besides 1 person who has used anal plugs on this forum, anyone else given it a try? I found 2 companies that make plugs. Renew Medical makes the most promising sounding one in my opinion. They are called Renew Inserts, made of silicone, soft, flexible, so they contour to the rectum as you move around. They have a double seal for inside and outside the rectum. Coloplast makes the Peristeen Anal Plug that seals from the inside.

I am going to try to get my colorectal doctor to prescribe me the Renew Inserts. The video on the website shows how it works: https://renew-medical.com/about-renew-inserts/
