Prohibition isn't the universe's way, deleterious affects are. That which does not conform (to advance life), leads to punishment (STD's, lower birthrates, dysfunctional society)…
Sex as a NATAL act, and relationship/family building act provides power to build (a society). Used in another way, the power to retard, & dissolve.
The choice is ours. Build or destroy.
Our society used to choose to build, since it achieved greatness via this, and began letting in others, and their influence, it has been choosing the latter.
