The first yaoi that I read and got me into it was a Touken Ranbu doujinshi. I didn't care about those stuff before.
Gravitation, an anime.
This is gonna sound generic but Junjo Romantica. It was my first yaoi and I fell in love w the genre after reading it lmao
My yaoi virginity was taken by ten Count, I was actually really shook idk what yaoi was at the time so I was quaking when the actually had sex
Finding Owari No Seraph ship fanart led me to discovering yaoi and my first official yaoi was blood bank
So the thing that got me interested in yaoi is maiden rose, and I first saw the OVA's of it and I was shocked at it. I had never even seen anything like it before. But I loved it and read the manga after so that I actually understood what was happening in the ova's.
Oh my god, same. When the dicks popped out I actually covered the screen using my hand. Ah, the good ol' innocent days.
What manga or manhwua made you intrested in yaoi?
