I only wear them privately. I'm the only person who knows I'm ABDL (my mother caught me once when I was 12 or 13, and I told a friend about it when I was maybe 10 or 11. But neither of them knew the extent of it for me. My mom just thought it was some weird fluke, and I think my friend thought it was just me sort of regressing a bit when I was 4 or 5. My friend thought it was really weird though, so after that I decided never to tell anyone else). I like keeping it that way.
Personally, I'm confident in myself and unashamed. But the world is a cruel place, and I have no desire to risk sharing my ABDL side with anyone else and having my life ruined. I'd never hear the end of that if it got around that I was into it. Plus, I feel like even meeting other ABDL folks in person would be risky and kind of weird for me. The only reason I'd want to meet another diaper lover is if that person was a woman, and if she wanted to have ABDL-type sex on a casual basis. But even then, that would be risky for me. I can only imagine what would happen if I became a public figure someday and had that used against me as blackmail. I'd hate to become the punchline of an SNL skit. I'm not sure that I'll ever risk it. I'm happy with keeping my ABDL side private.
