Wow! I'm so happy you guys have been able to share it like that! Was he scared you'd reject him over it? I have not yet admitted it too my wife, or even out loud. I'm very similar to your hubby, I grew up ashamed of it, and a lot of stuff.
I always thought it was a fetish, and mostly sexual for me. I've known I've had an attraction to baby stuff since I was maybe eight or nine, but I never acted on it at all until I was a teenager and discovered they made adult diapers and had them in my local drugstore! I found a sample pack and must have been the reddest I had ever been when I bought them. I hid them until I could be home alone. And I wore them and slept in them, and even used them!
It has been an every great once in a while thing, learning about lovely online communities like this one, realizing that while it's not “normal,” it's also not as uncommon as I thought. I've also realized there's nothing wrong with a little “little time,” and have given myself space to play with Legos and other stuff.
To be absolutely clear, my wife is my hero and a rock star, and would probably be accepting if not completely understanding of my AB side. I just have personal shame issues around some religious stuff and some childhood abuse stuff that I won't go into, so I haven't gotten over my fear to talk to her about it yet.
Anyway, thank you for your kind words, and every y'all for your wonderful selves. I'm happy to be here.
