Hello, I'm a DL and have been for many many years. However, my wife who I have been dating/married for 15 years still has no clue. In fact, no one know my little secret. This is just something for me, a personal feeling that I enjoy when I'm alone. I'm not an Adult Baby but I just enjoy wearing diapers.
I've worn them in private, public, for fun, and for arousal. I would love to have my wife know about the secret me and join in, but honestly, the thought of telling her is not something I think I'm prepared to do.
