We are so far gone that people don’t even realize that the biggest problem is the extended childhood created by our dumbed-down schooling system which created a new demographic for which a new word - “adolescence” - had to be created. It did not exist prior to mass schooling, and many people married at ages most today would consider to be children. It was the norm. The real measure of whether one is ready for sex is being able to accept adult responsibility and get married. If that is age 15 then so be it. At the same time, there are too many 25 year-olds to count who are not mature enough to be sexually active, and it is wrong for a man to take advantage of them.
