i am a 60 year old married man who is wearing nappies again now 24/7 for nearly 12 years. Before that i just wore to bed at night.
Growing up i wore nappies or training pants well into my late teens early 20's. Once back in nappies 24/7 my wife started a gradual process of regression....nothing sudden just gradual small steps.
Now i am nearly a baby again.
