Adults...In Diapers?!

An Adult "Baby"

I have a friend who is, ...well, someone who wears diapers - as an adult. Adult Baby/Diaper Lovers even have communities online! There's absolutely no way to give my opinion on this subject without sounding judgmental and degrading. After doing a little research on the topic, I've come to a set-in-stone conclusion: this is something I don't even want to understand, know more about, or become enlightened about.

As for my friend? They know that I accept them for who and what they are, and as long as they don't involve me in it, I'm good. If I feel the subject being forced upon me, I'll get vocal (and that's when I tend to hurt feelings), but as long as it stays "over there," I can deal with its presence.

Once, when I was much younger, I saw a TV show based on this kind of thing. I couldn't wrap my mind around it then, either. It was on Discovery or some similar channel, I think.

So does anyone else know someone who does this? Are you an adult who wears diapers? What reactions have you gotten (or given, if you're the friend of one) to this very private part of your life?

*For the sake of my not wanting to know any more than I do about this, please keep the details to a minimum. I read every comment. After all, I did my best to not offend you; all I ask for is the same courtesy. Thank you.
