Just Found Out I'm Into DDLG

I recently started exploring my kinks more seriously and found out something surprising. Just last night at work, while pouring a drink for an older couple who seemed really into each other in that playful parent-child kind of way, it hit me. The idea of being in a dominant little role with someone made me feel this weird mix of excitement and nervousness that I couldn't shake off all day. It's like suddenly understanding why certain scenes from movies or books that I didn't pay much attention to before are so compelling now. Today, I even caught myself blushing when one of my friends mentioned something about a DDLG relationship online. What does it mean? Should I try talking to someone who understands this better? Am I weird for finding this out now in my twenties?
