I've been a lurker here for years, I'd like to finally contribute.
I wore diapers until I was in kindergarten, and started up again when I was 14 for fun. I wear them in public a lot, including my job, but I don't flaunt it. I don't see why people are so afraid to do so. There's no law against it, and millions of people have to wear them for medical reasons.
I love how secure they make me feel, it's such an interesting mix of comfort and confidence and vulnerability. It can be a sexual thing, but mostly it's just a wonderful thing.
I hope to make some friends here.
