Oo, I kinda did with Kuroko no Basuke and Haikyuu. I was so curious with Kuroko, but I kept putting it off, until I came across a somewhat pervy dj with Kuroko, Kagami, and Aomine I fell in love with Gusari's dj's about Takao and Midorima and I saw she did one for Haikyuu and curiosity got the best of me, haha

Only Yoneda Kou's doujinshi from Katekyo hitman reborn, I believe. It was years ago tho.. I didn't even know it was a doujinshi when I read it. I've watched KHR since then but it kinda took a long time before I realized they were connected lol.
In general I don't like reading doujinshi if I haven't watched the anime. I just can't get into it.
On the other hand, many times I've seen cute fanart and wanted to check out the anime.
What yaoi doujins have you read first before reading the actual story? Or still haven't read them?
I found Haikyuu through a Kagehina dj, and I'm debating whether I should read Gintama from all the yaoi djs I've read about Gintoki and Hijikata.
