The first anime I saw was Voltron as a wee lad, but I remember getting my first taste of anime back in the 90s when SciFi played anime movies each Saturday. Vampire Hunter D, The Venus Wars, Tenchi Muyo and so on.
When Toonami was at it's peak (the first 5 years of the 2000s), I watched it religiously. That was back in high school and a little after high school. I remember my first hentai movie I watched. Legend Of The Overfiend. YEAH BUDDY!!!!!
