I hate to break it to you, but sex sells. Always has. There's a reason the Arabian Nights has been on the shelf for two hundred years.
As for lolis, up until a century ago you were lucky to live to see twenty and most people were married by twelve and shortly pregnant there after. I believe in Japan the age limit is seriously much lower than here. And inA merica up until the mid fifties it was practically expected for example that a dance instructor would have sex with ten year olds.
In anime also someone who looks ten may actually be 3000 or more and someone who looks 30 could be hours old.
In fact you could say giving them overly large breasts is a way to age them up so people do not feel too bad about lusting after junior high girls like Kagome or Misty from Pokemon. or just catering to the fact that the shows are targeted towards horny teenagers, male and female. Not to mention based on Disney, who pioneered this sort of thing.
Do you WANT cartoons about middle aged people?
Teenage boy
Middle aged man
It doesn't seem overly problematic. It seems to be working quite well in fact.
