This discussion is about a product called an "ostomy suction cup," which is designed to cover the stoma after a shower, allowing you to dry off and prepare a new appliance without needing to hold anything in place. The idea is to make the process hands-free, but there are some concerns and experiences shared by others in the community.

Here are some insights and advice from the discussion:

1. Concerns about Fit and Safety:
- Some people worry that the suction cup might press too hard on the stoma, potentially causing injury or bleeding.
- There is a risk that the cup could be dislodged by a strong output from the stoma.
- Those with larger stomas are concerned about whether the cup will fit properly, as it only comes in two sizes.
- Suction might actually increase output from an active stoma.

2. Suitability for Different Types of Ostomies:
- People with colostomies often find that using toilet paper or paper towels works well enough and doubt the cup could handle a sudden output.
- Urostomy users with smaller stomas see some potential in the product, as their output is continuous but low in volume. However, the device would need to be emptied and cleaned after each use.

3. Product Details:
- The suction cup is priced at about $20 and is available on myostomy.live.
- It comes in two different diameters and is demonstrated with paste only, without a barrier ring.

4. Tips for Application and Alternatives:
- If using paste, it's suggested to apply your wafer first and then work the paste in as you attach the cup.
- A do-it-yourself option involves cutting the plastic ring from a Hollister pouch and attaching a small plastic container to create a removable cap.
- A cardboard toilet-paper roll can serve as a quick, disposable shield that allows output to escape.
- Many people prefer to change their bags first thing in the morning when the stoma is less active. Covering the stoma with folded toilet paper immediately after removing the old pouch can prevent most leaks, with some claiming a 99% success rate.

5. General Sentiment:
- While the idea of a temporary, stick-on cover is appealing, especially for those with highly active stomas, many remain cautious about using suction directly on the delicate stoma tissue.
