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.
You asked them about it? You just go up to strangers and ask them about their bedroom habits, and why they do what they do?
By the way, don't you think I'm a "diehard Catholic"? Doesn't my opinion (which is fact, BTW, not just opinion) count for anything?
Incidentally, I know just about all the "diehard Catholics" in a city of a million people. None of them have 16 children.
Do you understand that an act of intercourse can be physically pleasurable, emotionally satisfying and procreative all at the same time?
This is crazy. Without some level of pleasure or lust there is no sex for it is physically impossible. It does require some level of arousement. BTW, all the Catholics I know with large families tend to be highly aroused by their mate.
