Too bad for them. What with porn, artificial toys, and contraception, these (not) Christian (not) couples make their masturbatory "sexual relationship encounters" fraudulent. The truth is, they have never in their lives had real sex.
In case you haven’t gotten the word; sex between a married husband and wife is supposed to be fun. It’s not just for procreation.
BTW, what do you think Song of Solomon is all about?
