I would warn against staying in a wet diaper for more than 4-5 hours, or at least use some baby powder to protect yourself. If you're not incontinent, I would suggest wearing diapers less often or staying in a dry one longer as better ways to save money. Especially make sure you always change after you poop, because sitting in poop is really harmful for your skin. What causes diaper rash is the way the chemicals in your pee are broken down when it mixes with poop. Pee alone is less harmful, but still not good to be sitting in.
