First anime I watched was DBZ and Sailor Moon, both on Cartoon Network's Toonami.
I was only like 7 or 8 years old back then, I think. I actually liked Sailor Moon a bit more than DBZ. I think it had a bit better storyline even with
all the edits to the US version. Or maybe it was just because of the girls... Either way I think I was looked at a bit weird for liking a "girly" show.
I actually don't think I realized the shows were imported from Japan until later.
After that, it was Pokemon. Everything Pokemon. I got Pokemon Blue and Pokemon cards and some limited edition Burger King Pokemon Gold Plated Trading Card. I found Missingno. and used the "clone glitch" in Silver/Gold. Haven't really played or watched any Pokemon in a while though.
Then there was also Cardcaptor Sakura on KidsWB and Zoids and either Gundam G or Gundam Wing or "Something" Gundam (I forget) on CN. I remember that as it was the first time I remember seeing a
real Japanese anime ending, not some edited remake. ("Shining Finger! Something something something!")
Sad how Toonami is gone... :/
I *think* it was around 2005 when I first encountered hentai. I watched whatever was on TV, until one day I found Inuyasha playing on Adult Swim. That led later led me to watch Bleach and Blood+ and then Code Geass. And then Gurren Lagann on
Sci-Fi "SyFy".
Now it's mainly Crunchroll/Hulu/Netflix, along with some fansubs.
And I'm asian, so maybe that means something.
