Wait, are you implying you've read every single non h 2hu doujin?
There's 61 pages of translated doujinshi on sad panda.
No no no, not all! I've probably read around half though. Maybe more? It's hard to tell, It's not like I started at one end and just read everything one by one.
Usually I'll search for a 2hu's name (and I've been through a loooot), and go from oldest to newest. If I find that a story is really good, I'll open a search with the circle in another tab and go on reading all of their other Touhou works too.
