A character or (heaven forbid) person who, despite attracting and/or surrounding themselves with people (usually physically and socially attractive) who are either overly sensual or always seem to find themselves in less that innocent situations, want nothing to do with or are scared/disgusted with(of) sex or intimate actions with said persons (or anyone else for that matter), regardless of their feelings toward them.
Person A: How is it that he's able to attract all the finest women in the school to just short of them smoothing him with their cleavage, but run away when ever things get too saucy?
Person B: Kid's a total Anime Virgin.
Person A: I guess so....reel 'em in just to toss em back. What a punk bitch.
