When you do wear diapers full time and start using the diapers for peeing and pooping or even just peeing in then eventually you could start losing bladder control.
That would mean you would lose part of your potty training by wearing and using diapers because you would get used to peeing in the diaper and not holding it in.
I have been wearing diapers full time for almost 9 years now and I no longer use a toilet and I will always start peeing as soon as I get some pee in my bladder.
As soon as i feel my bladder filling up I begin to release the pee right away into the diaper instead of holding it in to make it to a toilet.
I also poop in the diaper as well.
If I were to ever stop wearing diapers and use the toilet again I would have to potty train myself to get my bladder muscles and bowel muscles working again.
Because I can not hold in my pee too long anymore.
I make a nice income working from home and so I can afford the diapers to wear all the time and I love my diapers and don't want to ever use the toilet anymore.
