Topic Explanation:
The discussion revolves around the use of convex barrier rings with flat stoma bags. The original poster is experiencing leaks with flat bags and is seeking advice on whether combining a convex barrier ring with a flat bag might be effective. They have been advised by their stoma nurse to use flat bags instead of convex ones, despite the issues they are facing. The poster is looking for personal experiences or advice from others who might have used a similar combination of products.

Advice and Insights:
1. Convex vs. Flat Barriers:
- Several users have expressed a preference for convex barriers over flat ones, citing better prevention of leaks. Convex barriers are generally seen as more effective for individuals with stoma output issues similar to those described by the original poster.

2. Combination of Products:
- One user mentioned using a convex barrier with a flat bag and found it helpful in managing leaks. This suggests that mixing product types might be a viable solution for some users.
- Another user shared their setup of using a moldable ring underneath a Hollister wafer, then attaching the bag, which might be a useful configuration to consider.

3. Personal Comfort and Suitability:
- It is emphasized that regardless of general advice, the most important factor is what works comfortably and effectively for the individual. Experimentation with different products and configurations might be necessary to find the best solution.
- One user highlighted the importance of having a sufficiently protruding stoma and flat skin around it for flat bags to work effectively, which might not be the case for everyone.

4. Self-Advocacy and Professional Guidance:
- Users are encouraged to discuss their concerns and preferences with their stoma nurses or healthcare providers. Understanding the rationale behind their recommendations can be crucial.
- It is also suggested that individuals should feel empowered to advocate for what feels right for their body, especially if the recommended products do not work as expected.

5. Alternative Techniques:
- One user described their method of using a protective skin barrier prep and a hair dryer to heat and soften the pouch before application, which has worked well for them despite previous issues with other methods. This highlights the importance of finding personalized techniques that cater to individual needs.
