Why do 1 st and 2 graders need to learn about anal sex ? The only thing they need to learn is never be alone with adults and teens without their parents permission and never let somebody touch or look at their genitals or show them theirs . They have zero capacity to understand fully . <| sep |> From the UK as well . While fanservice can be a little annoying , I ' m happy to just ignore it most of the time . But in Flip Flappers , with them being and looking very underaged . ehhh . it ' s a little creepy . It ' s the one thing about the show I don ' t like . However , it isn ' t common , luckily . I can only think of two episodes where it was bad . This one , and the one with Cocona showering on the island . Stuff like sexy Papika last episode when she was in the hotel with Cocona , I don ' t consider fanservice , as it actually contributed to the theme of the episode .
