..because like hunger and the pleasure of eating, it is part of survival of the species.
Pleasure is something we all like, but in the case of illicit relations, it can produce illegitimate offspring and cause complex social problems etc.
G-d has made us with a higher order than other creatures.
We are accountable for our deeds.
We make weapons and power stations and what-not
We create stable civilisations, with God's help.
It is part of the survival of the species, but it doesn't have to be.
I mean, the species can survive just fine if we only feel pleasure from sex when within marriage, right?
