Online porn is a burden, not a form of relief. If men are seeking 10s, 9s or 8s (like porn provides) then they will get the attitude that comes with a ‘10’. There are LOTS of real women who don’t come with the attittude.
Furthermore, abondonment of Christianity has lead to meaningless marrriages that end in divorce and adultery. Under a Christian marriage, two people become one unit where it is more important to consider what is best for the Unit rather than the self. A civil marriage without Chrisianity is just an enhanced date between two individuals.
The modern "church" wants to be seen as "relevant" by accepting the current cultural definitions. But the only way Christianity can be "relevant" is to be counter-cultural, and to live by the Word of God, and not the words of men.
