Premise — The ultimate purpose of sex is procreation
Sodomite Objection — “If the sole point of human sex was procreation, then women would literally only be able to have sex while ovulating.”
Answering the Objection — Notice I did not say “sole” point. I said “Ultimate purpose.” The ultimate purpose of sex, as God created sex, is procreation. This does not mean that sex does not have a proximate point(s) or purpose(s). One of which is union, pleasure, and fellowship between two married people.
It’s like eating. The ultimate purpose is to perpetuate our life. In His mercy, God blessed that activity so that it can also be enjoyable. Likewise, one can eat when one is not hungry and can pervert a perfectly lawful activity through gluttony or eating things that are very bad for us.
The ultimate purpose of sex—indeed, of everything—is to glorify God, which sodomite sex can never do.
And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the birds of the heavens, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth. And God created man in his own image, in the image of God created he him; male and female created he them. And God blessed them: and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it; and have dominion over the fish of the sea, and over the birds of the heavens, and over every living thing that moveth upon the earth. Genesis 1:26-28
