Sex is good. God designed it to be that way! As more and more scientific studies are completed and research papers published there is one thing becoming more and more clear—God’s way of having sex (a married husband and wife) is the best way to do it.
Pornography before or during marriage is a relationship killer.  Porn makes you objectify the other person, seeing them as an object to be used and not a person to be loved.  Porn creates unrealistic expectations that your spouse cannot live up to.  Even so-called “soft” porn is the open door to more destructive viewing habits.  Porn erodes the trust that holds a relationship together.  Porn isolates marriage partners from each other, because they think they can find satisfaction on a screen.
Having sex before marriage actually rewires your brain, making it so much harder to bond with your spouse after you say “I do.” Check this out:
For over a decade, there have been numerous studies that reveal three different attachment styles in the way people bond sexually: secure, anxious and avoidant. The latter is what’s interesting as it reflects the behavior we see in the statistics above.
According to Dr. [Sue] Johnson: “Those of us who are avoidant, that is, uncomfortable with emotional closeness and dependence on others, are more likely to have what I term ‘sealed-off sex.’ Sex is self-centered and self-affirming, a performance aimed at achieving climax and confirming one’s own sexual skill. Technique is prized; openness and vulnerability shunned. There is little foreplay, such as kissing or tender touching. And no cuddling afterward—once the Big Bang occurs, there’s nothing left … Because pleasure without emotional engagement is shallow and fleeting, this kind of sex needs continual boosting to be thrilling.”
God’s desire is for your sexual relationship with your spouse to be intoxicating! The descriptions in Scripture are of a husband and wife intoxicated with each other, and God pronouncing a blessing over the couple as they are wrapped up in each other! God wants sex in your marriage to be so amazingly good that there is never a shadow of a thought of looking anywhere else.
But if you want this, you must do sex God’s way. One man and one woman who are married to each other, and who have left behind all the entanglements of other partners, whether they’re real or virtual.
