I have:
6 extra large Rubbermaid tubs of Huggies Pull Ups, all of them Princess designs. Most are from the 2005-2015 ERA, but I have some that older and some that are newer. lots of Princess Jasmine, Belle and Cinderella designs, I have at least 300-400 pull ups with Princess Aurora (Sleeping Beauty) on them. I have other Princesses too but most them with those princesses. I have 6 large Rubbermaid tubs of Goodnites, most are from 2007-2016. Most of my l/lx are from 2007-2011. Again I have some older and newer ones. I have lots of the character Goodnites. I have a large amount of Disney Fairies Goodnites, a decent amount of Cinderella Goodnites and quite a few Elena of Avalor Goodnites. I also have 3 and a half packs of the Original DC Amor with the anime design and 5 packs of Rearz Princess Pink. 1 pack of Rearz Safari,l and 3 packs of Abena M4/L4.
In addition to all of that, I've noticed that some people have listed other not diapers stuff but still related. I'm going to add that in as well. So I also have a bit of a thing for Barbie. Although how could you not have a crush on her! So I have a tub of Barbie dolls. I also have 8 My Size Barbie dolls (3 ft tall dolls made in the mid 2000's). I found that a s/m Goodnite or a 4t-5t pull-up fits rather nicely on them. They are also made of hard plastic so it doesn't matter if the diaper is wet. Pee doesn't affect them and I found that it is actually kind of fun to pee on them. I also have a WM doll that I recently acquired.
TL/DR
Basically I like peeing on pretty ladies.
