Good point, Clare.
This day and age puts forward an activity that is normally less than 0.25% of human activity, and makes one's whole lifestyle revolve around it!
As if everything is either sex, something leading up to it, or something that makes it possible in some way. Give me a break!
It's hard to think about the concept of "marriage" these days without immediately thinking about the marital debt, the way the world has totally focused on sex.
In reality, we should think about discipline, teaching children, practicing the virtue of patience, doing hard work, a noisy house, children playing with toys and/or fighting, family hugs, the spouses working side by side, doing dishes and other chores, praying the Rosary together, etc. because those things take up WAY MORE TIME percentage wise than anything that happens in private between husband and wife.
Nevertheless, especially when I was single, those everyday things were NOT what I first thought of when someone said the word "marriage".
Maybe it's because I have watched TV and movies in the past (and listened to pop music) which placed those thoughts in my subconscious? Who knows.
