Yeah, it's very frustrating, a 20 year age difference doesn't really stop being creepy until the younger one is 30 if I'm being honest, but I accepted that if I was going to partake of this medium I'd have to put up with some minimum amount of pedo stuff. I'm sure it comes from Japan being a super repressed country just like the US, but in the opposite direction, and the fact they have a highly rigid hierarchical society.
