Age of Marriage?

[Jenny A]

The more I think about, the more most marriages these days seem to resemble a Porn movie.

I say this because most married people seem to have sex for the "fun of it" and not recognizing that it is indeed a sacred enterprise, not something like playing monopoly or a football game.

The function of it is to bear children, and so many people don't have the child bearing part of it in mind. It's just gross, selfish self fulfillment, no appreciation for the creative act. The attiude, even toward sex within marriage these days, is one of having their cake and eating it too.

Why is it, even in society that the essential baby-making part of sex is downplayed  to the hedonistic side of it (even within "sacred' marriages?)

Define sacred in a way which has any relivance in a godless world.
