Well, then society is broken, when i was a kid (8, 9), we had this English teacher every kid on the class has a hard on for, In hallowing she wore an almost transparent dress and the guys couldn't stop staring, people Obviously tough it was funny/normal behavioured for boys but had it been the other way around it would had been odd and the parents wouldn't had liked it.
The society is sexist, big surprise there, kids are just little humans, that really seems to be a surprise for some people, coating the world around them is a TERRIBLE way of introducing them to society. That is an important part of Kodomo no Jikan
