Well, my brother maybe knows that I read yaoi, but I'm not sure.
He saw me watching Yuri on ice, and it was some Viktor and Yuri hugging scene, so he asked me about it, and was like "is this gay?".
And I just started talking about it and how they are cute together and how they kissed and that I ship them. (I really don't know why I did that)
And a...... reply
How and when did you guys discovered you are into guy x guy stuff? For me it was summer holiday before first year of high school, I was watching TV, then move "No night is too long" started and when I saw two guys kissing I was like "Damn, I like it, I want to see more..." It made me feel really excited. But I didn't start to read/watch yaoi until year ago.
