I think stuff around sexuality is something that has the power to make the smartest person do stupid things. There have been murders and even wars related to sexuality, I believe. It has such an effect to people that it must be controlled to keep us safe and healthy marriage sounds like a good framework for that. On the opposite sex drive let loose can lead to wherever one’s desires lead to and it most likely is harmful to all parties.
My 2 cents.
The problem can be that someone is seeking the pleasure - - not loving someone, but using people and/or oneself to get nice feelings
But God is so beautifully wonderful and pleasant and kind in His love >
"Your lovingkindness is better than life" (in Psalm 63:3)
And only with God can we have real intimacy.
"Now hope does not disappoint, because the love of God has been poured out in our hearts by the Holy Spirit who was given to us." (Romans 5:5)
"he who is joined to the Lord is one spirit with Him." (in 1 Corinthians 6:17)
In God's love we are intimate with God Himself sharing His own love with us "in our hearts", and we are intimate with one another who are in this love.
But sexual stuff can have someone only intimate with one's own feelings being produced inside one's own self . . . maybe using someone else, but not truly intimate in love with the person, but like I say having intimacy only with nice feelings.
And those nice feelings can not make a person strong against boredom and loneliness and frustration and anger and depression and unforgiveness and torment of worry. Nice feelings might cover up someone's deep trouble, and distract a person from his or her deep weakness and misery; however, weakness for such pleasures will keep a person weak for the suffering later.
So, we can see how even moral people can be weak for arguing and complaining and hurting each other! And they can bring up children who do not know how to love, and they are desperate for pleasure, instead. So sexual sensations can be quite the treasure for such kids.
And we see how ones in desperation for sexual pleasure have been going, not having intimacy with our Father.
And God has us intimate with one another, if we are sharing in His love: in this all-loving family caring and sharing love we are not limited to having intimacy with just some one person or in-crowd. And this love is almighty to keep us from being fools for pleasure and its false intimacy which is merely what we can make ourselves feel.
So it is important, then, not to get isolated only with some one person or ones we use for what we prefer for pleasure and excitement. Because God's love is all-loving and intimate in family caring and sharing, preparing us now for this for eternity.
