I am a diaperfur, as opposed to a babyfur (adult fursona who wears diapers). When it comes to diapers, I typically wear PeekABUs, MegaMaxes, Crinklz, and DinoRawrz.
I guess you think of a fursona you like and have that fursona be into age regression and wearing diapers. There’s also a section of the forums dedicated to babyfur and diaperfur subjects.
