Wow! What a find! I have always been a pad/tampon person. The idea of a reusable anything grosses me out, so when I saw these flex discs AND heard I could have sex without the mess, I had to try them. I am SO glad I did. These things works wonders. Easy to insert and easy to get out, I have had marathon sessions with the bf without any leaks or smells escaping. They are a little messy upon removal until you get the hang of it, but it's worth it and they last a lot longer than a single tampon. I also noticed that upon insertion I had some very mild cramping for about 10 minutes, but after that absolutely ZERO additional cramping. Dare I say these are a miracle? Either way I am converted and will never gp back to old school tampons.
