Sex is for procreation. That is its purpose in human beings. This does not mean that sex within a marriage that is open to procreation is not enjoyable, but when not open to new life sex ( whether within a marriage or not )is a perversion. If conception does not naturally occur that does not demean the act
“Sex is for procreation. That is its purpose in human beings”
Nope, the purpose of human beings is to worship the Lord our God.
That you get that very basic premise incorrect makes me wonder.
So an older couple who have been married for years, she is past her change in life make love, that is a perversion in your view?
Where is that written in the Bible?
