Maybe they were used by a husband and wife but I seriously doubt it. It reminds me of Proverbs 5 where the writer doesn’t deny that there is initial pleasure in the arms of the forbidden woman. Sex is pleasurable – the couple in the park probably enjoyed their brief time together.
But the writer of Proverbs goes on to say that the pleasures outside of God’s intention for sex within the covenant of marriage are very short lived.
At the end of your life you will groan, when your flesh and body are spent. You will say, “How I hated discipline! How my heart spurned correction! Proverbs 5:11-12
Why do we set our sights so low? Hiding in the park? There must be more to sex.
There is more but we settle for so little.
