@Tcof Japan has a rather conservative culture. Although sexual desire is considered an important and natural part of male identity, an open interest in sex is still condemned. Attitudes toward sexual interest in girls are much worse due to the stereotype that women who love lewd things are spoiled and dirty.
Japan allows porn to increase intention to make a child, but somehow their birth rate been in decline or stagnant.
Most seems to be more interested with a fictional character like this boy.
