Thank you for this Ask ^^, it’s a very good one! When I haven’t worn a nappy for some time, the desire to wear does grow. Though, I try not to let it bother me to the point where it would harm me.
It’s like when you haven’t eaten your favourite dish in a while. You remember its flavour and how it makes you feel. You want to eat it again, and you look forward to the next time the opportunity rises ^^
