The issue of pornography and masturbation needs to be dealt with before one even considers getting married, because it cannot and will not be addressed by getting married, since it is an issue of spiritual captivity and needs to be dealt with by prayer for deliverance. I must say that I am one person who was born again but still doing these things even though I was married, it was after many months of prayer and reading the word, that I was finally free from it. Today I can safely say I am free from it because it has never come to mind to indulge in such, even though I'm currently not married. It also helps to keep yourself away from such things in your life that would make you want to engage in such. Although you can't remove yourself from buying in the market, but you can fill your mind with the word of God, remember the Bible says it is the sword of the spirit. And one of the words that really stopped me in my tracks when it comes to the issue of lust, is in Matthew 5:28-30 (NKJV) But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart.
If your right eye causes you to sin, pluck it out and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell.
And if your right hand causes you to sin, cut it off and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell.
Jesus was addressing the issue of gratifying one's self by lustfully looking at a (woman or man for that matter) and thinking you have not sinned because you have not touched her/him. Jesus says even looking at a person with lust is the same sin as if you'd actually had sex with them. This is paramount to understanding why pornography is a sin, because you look at a (naked) person and lust for them,which then results in gratifying yourself with masturbation. The second issue is that if your eye causes you to sin, pluck it out rather than go to hell. Here he addresses the issue of self control as you are trying to stay away from sin, that you should hate to engage in sin so much that you are willing to go to the extreme, as much as cutting off parts of your body, just to make sure that you don't sin. That is very significant, because it means you have to make every effort to stay away from sin. If it means leaving a church because people there dress indecently, that would be what you do. If it means looking away if you see a skimpily dressed woman walking down the street, that would be what you do. If it means blocking certain websites or getting rid of television to prevent you seeing indecency, that is what you will do.
What Paul was talking about in 1 Corinthians 7:9 is different from the issue of pornography and masturbation.
Matthew 19:8-12 (NKJV) He said to them, "Moses, because of the hardness of your hearts, permitted you to divorce your wives, but from the beginning it was not so.
And I say to you, whoever divorces his wife, except for sexual immorality, and marries another, commits adultery; and whoever marries her who is divorced commits adultery."
His disciples said to Him, "If such is the case of the man with his wife, it is better not to marry."
But He said to them, "All cannot accept this saying, but only those to whom it has been given:
For there are eunuchs who were born thus from their mother's womb, and there are eunuchs who were made eunuchs by men, and there are eunuchs who have made themselves eunuchs for the kingdom of heaven's sake. He who is able to accept it, let him accept it."
If you look at the highlighted, Jesus was addressing the issue of not getting married (and subsequently being celibate), that not everyone has been given this ability to stay celibate or unmarried. Which then means because not everyone can do it, the rest can marry. This is the same mind that Paul was writing about. If you look at verse 8, Paul says its good for the widowed and unmarried to remain so, like him. You can then deduce that Paul was also one of those that Jesus referred to as being given to be celibate. But Paul was then saying again because not everyone can be celibate then it is better they marry, than to burn with passion, because it is not something that is in them to stay without a woman/man. This verse is not addressing lust as in pornography and maturation, but rather the desire to be married and have sexual relations on a regular basis.
