But surely most 35-year olds would say that they changed much less drastically from 25 to 35 than 16 to 25. I mean would you say it’s ok to have sex with 12 year olds since they “never stop maturing” and who’s to pick a number? I think we can pick a number: don’t have sex with people who are barely out of middle school. It doesn’t need to be scientifically verified; it is simply common decency. It is frankly disappointing that in 2019 this is a controversial statement at all.
