Sex has nothing to do with emotional or mental maturity except with more education you are less likely to have casual sex. It has nothing to do with “becoming a man or woman”. Plenty of adults are extremely accomplished without getting sex involved. Sex is literally just an act of putting your genitals together. How does that make an adult from a child? It doesnt.
Teenagers slept around because they were bored. Now they can learn coding and game. They are legitimately using less drugs. Drinking less and having sex left because they are busy developing skills for work and life.
