Im seeing that a lot of persons replied under a different question that their first yaoi was either junjou romantica or Sekaiichi Hatsukoi. These were the first yaoi I read as well so I wanted to know how much person had the same experience.
I think it was "Love Stage!!"? I can't remember if it was that or some random doujin or lewd yaoi manga that I accidentally found somewhere. The more I try to remember the more I think it was a random lewd yaoi manga... 1 reply
