Honestly, I can't think of anything other than that...
He means do you just pee...or something else or maybe he is curious if anyone does anything else with their diapers. No need to be sarcastic with your answer.
I wet only. I've tried pooping, but it's just too hard to clean up and I can't stand the smell(I'm not going to like changing my kid's diapers, I can tell). I jerk off in them after I've wet and read some TB/DL stories.
I wear when I can or feel in the mood. Its an interesting feel to have the padding all around. I will then wet when I can. Never messed, and highly doubt I would ever want to do that. -D
Well aside from wearing them and using them, I also use them as my one of my awesome super butt-kickers for my time when I act as a super hero and want to hit someone upside the head, but with something soft and fluffy.
