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.

Yes, you are quite right, I forgot to mention that part, and that is a very important part of sex within marriage, it was a mistake leaving it out, I thank you for correcting the mistake. God Bless
