If I did my research correctly, "puppy", or basically almost always used as "pup" is used in power dynamic play. I think, on public space, you'll be fine as Lillie. Perhaps even Princess Lillie, just just princess. But "pup" is going a tad bit too far
@Sono But I'm not using it like that, just as a name that makes me happy. @Faust03 Well it's a good thing I'll be going by both then!
