I was born in the early 40’s so all they had were cloth diapers. As for my preference today, it came about when I was 6-9 yo and punished in diapers to shame me into behaving. The diapers were Curity 21x40 and I remember being pinned in them while the other children watched as added humiliation. I’ve tried many disposables over the years but nothing excites or feels as good as the soft cloth diaper. Being pinned into them instead of taped, also seems to add greatly to the humiliation and shame that seems the core pleasure I get. Sadly, they stopped making Curity cloth diapers but I found some adult cloth diapers on Amazon and EBay that are almost as good. Now if I could only find a mommy that would like to spank me and pin me into some diapers.
I wore disposable diapers until I was sometime between 3 and 4. Looking at my old photos, it appears that I wore plastic backed diapers. 5 years later, I discovered that they make tape diapers for people older than toddlers, but some of the first bigger diapers that I saw were blue, and therefore, I developed a preference for blue diapers over plain white diapers to this day and I would only wear the blue ones (maybe pink too) in the future, when I’m on my own.
