That's not quite what the official catechism of the Catholic Church (http://goo.gl/dA6In) says (indeed, it mentions "love" quite a few times in discussion of the Sacrament of Holy Matrimony), but even if it were, I do suspect that there are more than a few people out there, including Catholics, who think that there's much, much more to marriage (or even "having a family") than just creating offspring.

Catholic League’s Bill Donohue: ‘Everyone In Their Right Mind Knows Marriage Isn’t About Love’ | The New Civil Rights Movement
Catholic League head Bill Donohue says “everyone knows in their right mind the whole purpose of marriage is to have a family. It’s not about making people happy, it’s not about love.”
So when do we begin mandating fertility tests for couples planning to be married? Or for married couples who haven't had any children in the last year? And what do we do about the fact that it's possible to have children without being married?
Incidentally, we don't know that heterosexual couples are “raising very healthy and well-adjusted children.” The prisons and mental hospitals are full of the offspring of married heterosexuals.
Furthermore, while there is a difference between wearing a shirt made from mixed fibers and homosexuality, the fact is that God prohibits both in Leviticus. There is a difference between murder and taking the Lord's name in vain, but there are commandments against each. At what point did it become acceptable decide that some of God's edicts should be ignored?
Hypocrite.
In answer to your questions, +Scott Randel : (1) Unnecessary, so long as a miracle is prayed for and allowed to occur. (2) Clearly they are going to Hell. (3) See #2, also, The Scarlet Letter and the desirability of criminal laws against fornication.
As to the Leviticus question, clearly you have missed the careful analysis of the various laws in question (see https://hill-kleerup.org/blog/2012/06/13/76-things-banned-in-leviticus-and-their-penalties.html) and missed that Levitican laws are of three types (civil, ceremonial, and moral), and that True Christians are only bound by the latter, which conveniently match what they want to be bound by (see, for example, http://www.frc.org/issueanalysis/leviticus-jesus-and-homosexuality-some-thoughts-on-honest-interpretation).
There's also some commentary here (http://www.myjewishlearning.com/blog/keshet/2013/04/08/its-the-purity-stupid-reading-leviticus-in-context/) that is interesting. Of course, it's not from a devout Catholic like Bill D., so clearly it can be discounted as a meaningful or insightful commentary on Old Testament law.
How convenient! Can we do that with everything?
No. Only Bill can. He's special.
