Why do you want to look at younger girls?
Because it's not worth paying for all that plastic surgery.
It is okay not to be attracted to people who make themselves look younger with plastic surgery but it is not good to look at young girls. It could get you beat up if people see you do that.
Nobody will beat me up because I'm big and strong. I bet those small girls could never win.
It's not about that, but you could get in trouble with the law. There is help you can seek to curb your attraction to young girls.
