I have a serious question. It's been on my mind a lot. I know mangas, especially yaoi, are all about the extra-ordinary, most of them are born out of fantasies but, truly, there's no smoke without fire. So ARE BOYS KIND OF ANDROGYNOUS in Japan and Korea??
How many yaoi, have I read when the boy has that long hair, has always been compared to a girl, or is just girly. I'm not saying there is something wrong with that, this is not the point here. And I know, you'll say it's fiction or yaoi is just outrageous but there are some real grounded work here that still uses this. So if someone from those places, or someone who knows could enlighten me, that would really scratch an itch for me, thanks.
