My wife likes the Dale Medical 316 ...we usually get a single from Amazon and they tend to last about a year. They also have ten packs if you go through them faster.
I also struggle with adhesives and I used a leg strap rather than a patch adhesive to secure my catheter after meta. That way I could also turn it when I was laying on my side so that the catheter ran down the front of my thigh rather than the side, to avoid squishing it.
These worked well for me, the elastic didn’t wear out too quickly. I would usually wear one during the day and then wear it in the shower and change it afterward: https://www.amazon.com/Dale-Medical-Products-Hold-N-Place-Catheter/dp/B00PP8VO8E
