Oof I've got a lot, but if I had to list 'em out:
Shotas: Tai from Digimon, Dipper, Ben Tennyson, Oliver from Ni No Kuni, Sosuke from Ponyo, Ash Ketchum idk if Terrence from Foster's Home counts, but throw him up there too. I also have plenty that I used to have the serious hots for but kinda lost a bit like Johnny Test, Gumball Watterson, Phineas Flynn, not that I don't like these boys I'm just not as head-over-heels in love with them as I used to be lol. You might notice a lot of my favs are either really cute and innocent and some are kinda rowdy boy-ish types, my taste in boys ranges between those two types a lot.
Lolis: Buttercup, Toph Beifong, Adeleine from Kirby 64, Pan from Dragon Ball GT, Isabella, we'll throw the Kanker sisters up here too while we're at it. I'm sure I've got plenty more I just can't think of 'em right now. I'm a real big fan of the tomboy, rough and tumble kinda gals as you might be able to tell lol I also really like more unconventional types of girls too, ones that are a lil more on the weird or ugly side I end up finding more attractive oddly enough.
