Pardon, where has the Pope ever said it was wrong for married people to have sex for pleasure?
Oh, wait: he hasn't. In fact, he wrote a book advocating it. In fact, the idea that Catholics believe sex is only for procreation is just another thing that "everybody knows," but that isn't true.
Majority of diehard Catholics I know have five six up to sixteen children. They did not believe in sex for pleasure just procreation. There is nothing wrong with that. THey learned that somewhere in the church.
Wait a minute, Campion.
While it is perfectly good for married people to enjoy the physical pleasure which accompanies sex, the Church does not teach that sex undertaken purely for physical pleasure is moral.
The Pope's allocutions collected in the volume The Theology of the Body make this quite clear.
