Well one way for discomfort is this well used, and a lot of fun idea.
Get some pantyhose, panties, panty-girdle, a corset, or a tight \all in one girdle, put all of this on under your regular clothes. Lock your belt with
a pad lock so you can not remove any clothing. Get all dressed up,
hop in the car, or better yet a train, and go for a long ride. Stop and
drink some fluids, coffee, tea, soda pop, etc. Now you can not go to the
bathroom until you get home and unlock your belt.
The tighter the better on the corsets add's to the pain, pleasure;
as you movements and your blatter are squeezed. Have fun.
