My wife and I, while on vacation, have used diapers as well as rubber pants over normal underpants after the insertion of suppositories. I should add my wife and I often become constipated while on vacation, and after a few days, my wife, although still somewhat embarrassed, agrees to the need for relief.
We usually go for a walk on the beach or in a wooded area, to make sort of a game of it to see who can hold out the longest. We've found that playful sexual stimulation seems to take the mind off of the need to go. while allowing the supps. to work more effectively. I'll provide a bit more detail later should anyone be interested, particularly any ladies who may still be "on the fence" regarding this subject.
