I started out as a wetter (pants & bed) and progressed to DL. AB doesn’t do it for me.
I started out hating being in diapers, got the internet and gradually started getting into ABDL as a whole. I don't know how many people remember it, I don't think it's online anymore, but the "Double Life of Ariel Crawford" was a big deal for me. What I did ultimately find was that a lot of the things I secretly enjoyed were AB things to begin with.
