Roman Catholic couples are being encouraged to pray together before they have sex.
A book published by a prominent Church group invites those setting out on married life to recite the specially-composed Prayer Before Making Love.
It is aimed at 'purifying their intentions' so that the act is not about selfishness or hedonism.
Considering that the Church is against contraception, maybe couples could also pray that sex not lead to pregnancy, at least not this time.
Oh, lead me not into temptation to keep going with this one.
