I was 17 when I first watched a yaoi anime and checked a yaoi manga out of curiosity and that was it for me. I just kept reading one after another lol.
I was 17, I started reading manga at 16 and one day asked if there where same-sex romance manga and people pointed out yaoi and yuri. Started with Gravitation anime.
i was 12 i'm now 13 so only around a year ago i think i started reading yaoi and BL because i got bored of hetero stuff and i wanted to see my ships together even if it was just fan made ╮( ̄▽ ̄)╭
