For me it was kind of standard. I watched Pokemon on Cartoon Network when I was younger, and then on some other channel I watched Naruto and Yugioh. After that, on Adult Swim they start airing shows like Bleach, and I watched that a ton too. Then on netflix I watched Elfen Lied and was hooked. I then started watching a lot more anime like Elfen Lied.
After a while I got into Yaoi because some of my friends introduced me to it, and it was just something of interest.
