I've been battling pornography since I was eleven. It's always been all the more "taboo" because I'm a woman, making it much more difficult to get help!
Without going into too much detail, I'll be straight forward: the lure to porn does not
go away once you get married. If anything, I have learned I must be on greater guard now than I ever was when single. See 1 Corinthians 7:32-35. Not only must I now worry of the Lord's things, but also my husband's.
It's easy to fall into the trap of making sex into an idol - after all, it's saturated into our culture. And it seems so easy coming from the media. That's why addictions often continue after the wedding day; real intimacy is hard work. Two people coming together as one is commitment: in time, energy, understanding....communication is vital in all aspects of marriage and every little detail will seep into the bedroom.
A marriage is a unity, a partnership; my beloved is my best friend. Sex is what offsets this one relationship from any other, making husband and wife in a consummated marriage. This is why 1 Corinthians 7:3-5 is so important, though it often (sadly) goes overlooked in today's church.
Churches and Christians in general tend to stifle discussion on sex, making it taboo or hush-hush, and that to me is a huge mistake. This makes sex out to be "bad", and because of a broken purity movement many struggle to see upon entering marriage that sex really is
a good thing... For me, it's an act of worship to give myself mind/body/spirit in my entirety to my husband. In a society that is sex-driven we should be teaching the truth straight from God's Word. Sex in its rightful place (marriage) is GOOD! 1 Corinthians 7 and Song of Songs alone have a lot to say on the matter, and those are just the two "obvious" areas that come to me.
Regarding lust, Scripture helped me throw off the weight of shame and guilt that I carried into this relationship....chains that I carried for fourteen years have been broken. It taught me to better appreciate the dynamic that Christ has laid before us, His bride - the love that He gives so freely, that my spouse has shown likewise...it's a reminder that the best is yet to come!
In the end, marriage means taking on more responsibility in the fight against lust. Satan wants to destroy what's sacred; we have to hold firm to what is true.
