Stunned66, welcome to the site. I have been a AB/DL all of my life, and married for a good while. I kept it hidden from her until last March when she discovered my diaper order from Amazon.com. She actually took it quite well and supports me, just as I support her with her diabetes. She knew that I had had an affair with my male room mate all throughout college which I told her before we got married, but I was too embarassed to tell her about liking diapers. I also never told my room mate, even though we did pretty much everything imaginable, so I think I understand from where you are coming.
Being an adult baby or a diaper lover is something that most of us have realized is a part of us since either our early childhood, as in my case, or adolescence. We have debated the causes for such, The general consensus is that it is rooted in early potty training trauma, separation anxiety, or abuse. I was adopted at age 2, so mine may be a combination of all three. Anyway, I'm sure you will have a lot of questions. There are a lot of good threads dealing with all kinds of issues which will really help. You will also notice that most of the members on this site are both young and very bright. The site originally started out for teens, some of which eventually got older and wanted to remain on the site. It then opened up for adults such as myself.
ADISC is a great site with terrific members. Sometimes we get a little heated and into each other's faces, but that's because we are sort of like family. We're all here to help. Don't hesitate to ask questions or pm individual members. We support each other.
