In every other generation we've all had to mess with puberty and endure primal sexual thoughts/impulses interfering with our "intellectual"/moral selves (unless you're the type that just gave in!). it's been an age-old problem of getting horn dogs under control for millenia - first baked into religion and then the laws of government.
