My wife of 31 years knows and doesnt mind me dressing up, but she doesnt really understand or participate alot, although she doesnt mind me dressing up for sex.
I wear panties under my clothes anytime Im not at work, and I wear panties and nightgowns to bed 6 nights a week. On saturdays I usually put multiple disposible diapers (3 Attends 10, and 1 Bambino) with pink plastic panties over them on by 10am. I keep them on till I wake up sunday morning, "lots of Desitin is required". I also put up my crib which is made out of 2 real baby cribs converted to surround a normal twin bed.
I wet myself alot and go out of my way to drink a ton of coffee, tea, ect... to insure I will be soaked by morning. Tried messing once but it didnt do much for me, although I recently bought some plain instant oatmeal and plan to try that out as filler.
