create implication bishounen -> androgynous
There will probably be some tiny example I didn't consider in which this may not fit (which I'm unaware of, if this is the case), but "bishounen" is used when men have androgynous traits. I feel this implication is fitting for the reason that a male must have "androgynous beauty" in order to be considered a bishounen.
This isn't the same as otoko no ko.
