As a pre-teen, wearing diapers were part of my general clothing. It was a routine that, right after school, I was diaper checked either by the sitter or by my mother. If I had an accident, then a bath would be given and then after the bath, I would be placed into a new diaper.
As I got older it was routine after every day that this was done automatically
After becoming a adult and having a gf-wife this continued to happen as well. It would not be announced, it would just be done. Sometimes, while at home during numerous activities.
