I shared it with my now wife on the first date. We didn't actually date though, we more or less interviewed each other. She is kinky so pretty open minded and shared with me her fantasies on the first date too.
I always find it interesting that those in the closet say bad things will happen if you go into public. I could post photos of my experiences with Heidylynn but they are already shared around this site.
Sounds like diaper trained to me. When I'm not in a diaper I have regular control, soon as I put a diaper on I get the urge to pee more frequently and stronger. It is very hard for me to hold back when I am wearing. I think of it similar to pavlovs dog. I have now associated my diapers with easy potty time.
I've worn around family quite a bit. Never was caught. You owe it to your wife to share this side of you. I've learned that withholding information from your significant other is never a good thing and leads to hurt in the long run.
