I discovered how wonderful diapers can make me feel down there thanks to finding a leftover box of pampers when I was five years old. It instantly created a kink in my brain before I understood what sexuality even was. It left me with this desire to be back in diapers that kept growing stronger throughout my childhood and was never leaving.
Just as I was turning 20 I had a spinal cord injury that left me fully incontinent, but I still had some sensation in all my important areas. Having zero control over my bladder and bowel wrote me a lifetime ticket to be in diapers 24/7.
I've been 24/7 since the early 90s. They still turn me on very much, I Love needing them and enjoying them.
