Usually as a way to relax, as I only really get aroused by them when I am desperate to have some - this only happens when I haven't got any. When I wear them I usually try to regress but so far this has been without success.
I wear them because they give me comfort. Solice from everyday worry. When I wear diapers I can feel young again. I can feel like all my cares and worries are somebody elses problem. They just feel good to me.
Of course they do come with there fringe benefits. Dont have to worry about bathroom breaks. Dont have to miss important activities. They also bring me a sense of self confidence and they remind me of the very important fact when dealing with people "they dont know what you dont tell or show them"
Usually when I go on a trip, I worry on where the nearest bathroom is. If there is no bathroom in sight, I usually kind of panic. With diapers, I know if I have to go, I just go. I guess a shortened way of saying this is that it relieves my anxiety.
