I try to limit it to 2 at a time really. Right now you could say I'm reading Malice Aforethought, Lookism and Dorohedoro.
Anime I'm not watching anything but need to finish Prison School and Beastars Season 1. I'm only 1 to a few episodes from finishing, but they're both kinda gross (Prison School in general, beastars because it's animals and the rabbit is a slut) so they're hard to watch while I eat.
My MAL currently watching/reading includes stuff I stopped watching/reading from like 2013....like Dennou Coil which Kyo said to let him know about after I watch it lol.
edit: just checked 18 anime I started in 2013, 1 in 2011 (Dr Slump) and they're just the ones with dates - there's defo more if I look at the update history.
