Welcome, man. You have been misled about Catholic teachings just slightly.
Yes, marriage is reserved for a man and a woman who are married, but each act of sexual intercourse need not be for the intent of producing children.
When you get married you need to [b:3s9fq0qo]open[/b:3s9fq0qo] to having children. In other words sex is not necessarily done for the sole purpose of having children, but that the 2 of you realize that’s how babies are made and in the event your wife gets pregnant you accept that child lovingly and as a gift from God.
This is not to say that each time you have sex that it needs to be expressly for reproduction. ” title=”Wink” />
