Welcome and congratulations for discovering this. I'm pretty new to this as well in regard to actually trying it a bit, but I've been interested in it for over 20 years. I'd say I'm 95% DL and maybe like 5% AB from afar for now, but that could change. Definitely take the time to meet the people here and elsewhere. The ABDL community is really awesome, and really accepting. Everyone can just be what they always wanted to be around each other, and can explore whatever abdl fantasy they want to without judgment.
For me, I always loved diapers since I was 9 or 10 years old. I have vivid memories of past accidents and always wondered "What if" if I could've been put back into them back then. You can read my About Me section for the brief story of what got me into the ABDL stuff. Definitely take the time to explore all the facets of ABDL and see what actually interests you and that you'd like to try.
I wish you luck, and if you ever want to chat about these feelings then I'm sure I or anyone else here would be open. I love to chat with the community about this stuff and explore together. Happy ABDLing, and stay diapered!
