Christianity doesn’t guarantee prosperity of every kind for every individual. Struggles in one’s health, one’s marriage, one’s work, and even one’s faith are par for the Christian course (Jas 1:3).
But, overall, we expect the biblical vision of the good life to produce a better life than the non-Christian vision. And (marital) sexuality is included. The Bible doesn’t deny that sin brings pleasure (Heb 11:25), only that the pleasure lasts or is worth having. Sin is always a denial of love for God and man.
So when I read secular sociologists coming to the same conclusion, I make a note, so that I may be ready to give an answer to everyone who asks me for a reason of the hope that is in me:
Hookup culture, strongly masculinized, demands carelessness, rewards callousness, and punishes kindness. In this scenario, both men and women have the opportunity to have sex, but neither is entirely free to love.
