Also, by definition a bishounen is young, as in 
not quite old enough to shave--then you get a 
biseinen, which is the more accurate term for, 
say, all them Fushigi Yugi guys.  Please note that 
"bishounen" doesn't apply to every dang anime guy 
you find cute (e.g. I have a thing for Vash and 
Gendo, but they sure ain't bishounen)--especially 
because outside of this fandom, the word isn't 
exactly complimentary.
