Like many others here I've had a desire to wear diapers since I was little. I remember, when I was around four, asking my mom to put me back in diapers. She complied, but since then I've had to keep my diaper wearing a secret.
I got married six years ago, and after a year or so I told my wife about my secret, and amazingly, she was understanding. So since then, I've been wearing diapers to bed five to six nights a week (I don't wear during the day - I like to be an adult sometimes!) thanks to my understanding and compassionate wife.
Everytime I put one on, I still feel a thrill and am amazed that I'm actually wearing one. There's nothing like having a thick comfortable diaper on. The other day my wife made it even more thrilling by dressing up as a nurse who diapered me and treated me like a little boy in the pediatric ward. That was nice!
