Yes, the source of the Roman Catholic Church's condemnation of Birth Control stems from this. The purpose of sex within marriage is children, and birth control eliminates this possibility. God Bless

Yes, that makes sense. I wonder, however, if that view -- one that ties together so closely proper human sexuality with baby making, a view devised principally by those who do not make babies -- is what keeps so many American Catholics from sharing their faith's official beliefs on the subject.

The purpose of sex within marriage is children...

That's not the whole truth. There is also the unitive purpose of sex in marriage. The two purposes are equally valid and important.
