When I have them, I wear for most of the day.
My situation is a little complicated. . . I wear at school, but not at home. They are not a problem at school, you cannot tell that I am wearing. At the very least nobody has said anything. (It's upper level college courses, so even if they did find out, they are smart enough to assume it may be medical.) My father, however, does not know and is an integral part of my life. If I wore at home, I would not be able to hide it from him.
So, only at school, when I have them to use. School is about to be out for the summer, so after these are gone, no more until August. I think my father may have caught a "whiff", that is a hint into the fact that I'm hiding something, so I may need to tell him soon before it blows up, but for now I'm happily diapered in class. (makes studying so much easier)
