I'm having flashbacks to my loop ileostomy. It was difficult, with part of it retracted.
For me at least, it got way better by around week 3 as some subtle swelling in my belly went down.
I managed it with a thick barrier-ring and some barrier-paste. I would cut the hole a tad bit larger than I would have otherwise cut, and managed the skin with skin-protectant wipes. It was a pain, though.
