I'm not sure I understand the question. Do I admit that I'm DL/AB? Admit it others? Admit it to me?
Well I finally admitted it, or more accurately, accepted it, years ago when I was 26. After years of being turned on by wet diapers and doing the "binge and purge" thing, I finally did accept that I love this, it's part of who I am, and I'm never going to stop. At the time I thought "Well this probably means I'll never find a girlfriend / get married because I'll never find a woman who understands." Then very soon after that, I DID.
As for admitting it to others, for the most part, no. I had one male friend years ago who was very liberal minded and told him about it, at the time he was a roommate and said he wouldn't care if I wore them around the apartment but I never did in front of him. A few years later we drifted apart as friends and he died a few years ago, but as far as I know he never told anybody.
I have other male friends who know I'm turned on by the idea of women wetting their panties and wearing diapers, and I've joked about me wearing them but I don't think they know that I'm really into it.
The older I get and the more open-minded society as a whole becomes, the less I care if anyone knows. I don't want my kids to know, though. If I didn't have them in my life I'd probably be a lot more open about it. Not sure how much my wife would allow, she prefers to keep it between the two of us--though she knows I occasionally like to wear them in public for the thrill of it.
