nah, I think it's ok. I was 12 when I started reading/liking yaoi. You reading yaoi at a young age could be worrying to some people, but if it's what you like and you're not hurting anyone by reading it, then by all means keep reading it!
I think I was also 10 or 11 when I started reading yaoi and I'm 18 now. There's nothing wrong with loving something passionately and I hope you keep lovig it in the future. But the question is, can you keep a secret? (≧∀≦)
Is it a bad thing that I'm an 11 year old and I'm into hard core yaoi?(づ ̄ ³ ̄)づ
