I do not work or go to school but of course I've done this; who hasn't? Silly question. Are there really people out there who try to force themselves to wait until they get HOME to defecate?
I always have the means of doing so--it's called my ass. Check back behind your balls; you should have one, too.
I have no compunctions about doing whatever I need to do in the bathroom. I don't really care where I am. Comes of having a weak stomach, I guess. Not going is sometimes not an option. I did have a friend in high school who wouldn't use the bathrooms there, though. He'd wait until he got home.
Of course. If you have a toilet available you go. It is bad for you to hold it. Why wouldn't I? Or have I been using the toilet for the wrong thing for over 30 years?
