It’s a line often heard in well-intentioned lessons on sexual purity:God created sex. It’s His. Pornography and premarital sex are just distortions of what God made that is good: sex within marriage. Those sexual desires you feel are good, you just need to channel them into marriage. (Or as often said, “toward your wife.”) All of the above is true and I have taught most of it myself in bits and pieces. But there are some major shortfalls to this type of teaching and mindset.
