I do. First met him online in the late 90s and after I moved to Virginia in 2012 I met up with him in person. He is the only person on the planet who both knows who I am and knows I like diapers. I'm incredibly secretive in that regard.
I met my first one recently, I had actually known her for a little while but just found out she was a diaper lover at another friends wedding when I asked my wife to bring me a diaper from the car and she said she had an extra I could have, so it turns out that she had a boyfriend that was dl and he got her hooked on diapers and wears most of the time. I have met 2 more guys since that I assume are ab/dl both of which were buying some old cushies i sold during the brief period that ab universe was closed. I didnt try to talk to them much as they seemed extremely timid and standoffish.
I've been to a few gatherings in the Austin area. Met up with a DL that posted on Craigslist once (just an informal meeting over lunch, mind out of gutter!) Years ago I met up with someone after exchanging some emails.
What I feel should be pointed out is that while there is no hard, fast numbers on who many AB/DLs there are, chances are there are a LOT more than most people even within the community realize. Chances are most of us have meet someone else interested and neither party had any idea.
Not really the point of the thread, but my guess is that at least 1 in 25,000 people fall into some category of the AB/DL group. That number could actually be MUCH higher. In the Austin area we used to have a monthly dinner munch. A rough guess of the population of Austin and the surrounding area is about 2,500,000. The groups was always 10 or more. Then consider that it wasn't always the same people, and there were always at least as many more that wanted to come but couldn't for whatever reason. Add to that those that didn't know about the munch, or were too afraid to be seen out in such a group. Very easy to say the area has 100 or more AB/DLs. Not a stretch to say there could be as many as 1000! If that was the case, 1000 out of 2,500,000 or 1 in 2,500!
Some prospective. If you think you're the only one in your small state, community, city and I'm even close at 1 in 25,000... You're likely not alone. I've even heard stories of small groups (3 or 4 friends) in towns under 10,000. Think about big sporting events with 100,000+ attending and all the people working the event. That means there's a good chance 4-5 are among us. Heck, next NFL or college football game you watch or attend there's a decent chance someone there is wearing a diaper!
I know one. He's my brother.
At least, I'm 90% sure he is. I've seen evidence of it, and I think he knows about me as well, but we never talk about it. Neither of us has so much as dropped a hint to each other, so it's kind of awkward knowing what we're both into without having said anything. It doesn't get in the way of our relationship though.
I've met up with two other ABDLs thanks to this site. I've gone to comic-con a few times with one and have met a couple times with the other. Because of work and debts I haven't been able to get out/travel much lately so it's been awhile since we've met up but we do chat from time to time.
I've worn before with one of them and it was fun and all. But overall they're cool people I'm glad I got to meet.
