I don't have finals, but I have to finish writing my thesis (doctor's thesis, so it takes a few years!). However, I can take as many bathroom breaks as I want in between, so no diapers necessary

(plus I often mind myself having some good inspiration for my thesis while holding on to my private part and staring at the gaping hole of the toilet bowl

).
I have worn a diaper to an exam twice in my previous educational career, but found that I was too stressed to use it in the exam room, so I had to go to the toilet after all. Besides, in a 5 hour exam, it's a blessing to have an opportunity to get away from your exam sheet for a minute or two.
I went to my German final earlier diapered and plan on wearing to at least one more. so lets hear it.
Deutschklausur in Windeln? Ich hoffe, dein Professor hat es nicht gemerkt! :tongueout:
