They not care. The Japanese are more open-minded than other countries in terms of sex. Specifically for my taste they take light years to other countries. They do not have so many prejudices. Thank God, there are no white knights in Japan and that's why we get amazing designs without censorship today. And as much as it bothers some of them this is part of their culture, manga and anime with designs of this type. And it will continue like that without changing, that luck that we have fans of the anime, the manga.
