Difficulties with wearing a device? discussion

Let me clear things up. I’ve gone back to wearing my full belt and after lots of adjusting, I still haven’t nailed the perfect fit. My question is: for the opening used when defecating, should it press firmly against your skin with cheeks separated? Or does it just need to hug the buttocks comfortably?

I’m a larger woman, and oddly enough, when I wear my belt looser, the holes don’t align properly but it feels cozy. Conversely, if I tighten it up, the openings mesh well together, though the fit is a bit less comfortable. With this tighter setup, I can handle about 8 hours before chafing becomes an issue for my health. Which approach is better? Should I just start wearing it and let my body adjust to having something right there, similar to how one adapts to a standard ball trap?

All these questions! Thanks:P Rachel
