The prayer asks God to:
"Place within us love that truly gives, tenderness that truly unites, self-offering that tells the truth and does not deceive, forgiveness that truly receives, loving physical union that welcomes. Open our hearts to you, to each other and to the goodness of your will."
The prayer is part of a prayer book for spouses that aims to offer support for Catholic couples throughout the different stages of marriage. While I see nothing wrong with people seeking advice from their faith, praying right before sex seems inappropriately timed. But that's just me. What do you think?
