I think it absolutely has something to with it. But, like Sofnday already pointed out, it's different for everybody.
For me, I may have been ready to be out of diapers physically when my mom toilet trained me (and I know she was ready!)But I think, I missed having my diapers. And, I don't know this for sure but it maybe why I like diapers. I missed them at an early age, and wanted them back. For someone else the story maybe different. Like, they were kept in diapers for longer and remember how nice it was, and later wanted to get back to that nice feeling. Same might be said for some bed wetters, they were returned to diapers, and grew to like the feeling.
What might contribute to one person liking diapers, may have no effect on another.
It maybe like a spark, sometimes a spark can land on something flammable, yet not light it up, while other times woosh! it goes.
I know some people who were forced to potty train, and went through all kinds of hell for it, and they like diapers.
While others, went though pretty normal uneventful potty training, and like diapers.
It's going to be different every time, is all that is to it.
Now, just go enjoy wearing your diapers!!! 😁 😁 😁
