I personally enjoy RPing potty training, even though I'm not someone with much inclination to wet or mess diapers, I just always enjoyed the tug-of-war with my AB Mama about her telling me to use the potty, and me protesting that 'Potty scary', before gradually learning to use it - to lots of praise. Therefore, I went with Enjoy mastering the potty, but I enjoy my big helping me cope with my 'fear' of potties first.
So...what are your feelings on playing at potty training. Do you like to try it and succeed to make your caretaker happy, or 'try' to use it but fail and need to keep your diaper on? Or does roleplaying with the potty simply seem boring or otherwise uninteresting to you?
