How to wear a diaper as an adult
Fold the diaper properly.
Before you put on your own diaper, make sure to fold it properly. Fold the diaper length-ways with the back sheet facing outwards; you don't want a hard crease, just a soft fold.
Make sure you do not touch the inside of the diaper. You do not want to contaminate it.
