1 Corinthians 7:2 Nevertheless, because of sexual immorality, let each man have his own wife, and let each woman have her own husband. 3 Let the husband render to his wife the affection due her, and likewise also the wife to her husband. 4 The wife does not have authority over her own body, but the husband does. And likewise the husband does not have authority over his own body, but the wife does. 5 Do not deprive one another except with consent for a time, that you may give yourselves to fasting and prayer; and come together again so that Satan does not tempt you because of your lack of self-control. (1Co 7:2 NKJ)
Now notice carefully what Paul is saying. He begins by explaining that the way to avoid fornication is to be married - so by implication any sort of sexual gratification outside of the union is fornication. hence masturbation is fornication and fornication is sin - the type of sin we read the church was to avoid (Acts 15:29).
This passage has nothing to do with teaching that sex or sexual gratification can only be had in marriage. If it taught that, it would contradict the Law, which Paul did not do. The sexual laws of the NT church were established by scripture, the OT.
RE: 1 Corinth. 7:2 The translators, not to mention preachers and many commentaries, have REALLY let us down in this passage. The word "have" in verse two doesn't mean to obtain a wife, it means to have sexual relations with your current spouse. (See 1 Cor.5:1, John 4:18, John Gill's commentary as well as others and better translations such as the NetBible and its commentary.) The first section then of 1 Corinthians is written to Christian couples and instructs them not to cheat each other of sex, because they would be tempted by "the porneias" (translated sexual immorality), but literally means, "the whoredoms", that is the sex brothels in Corinth in worship of Aphrodite, which would be a temptation for husbands being denied by their wives. We could extend this principle taught here to include other types of fornication, but we can't say it applies to masturbation, unless we can show that the Bible says masturbation is a type of fornication, sexual sin.
In v5 we see the final nail in the coffin - especially for males. This verse forbids one partner refusing the other satisfaction. Sex is not about selfish self fullfillment - it is about giving the other person what they need. Now how can we do that if we haqve just satisfied ourselves!
This is just silly. First of all, I'm always good for round two and the wife will be glad that I won't be a minute man, but seriously, we're not discussing denying one's spouse by masturbation; we're asking if there are times that it is acceptable in or out of marriage, and you have failed to prove your point. Even this passage teaches that we have a right to sexual satisfaction even to the point of having dominion over another person's body. However, a little common sense here goes a long way. It's necessary to understand figures of speech when reading any text, and we would not think to suggest that a spouse has total rights over his/her mate's body or mind, for that matter. It's a joint "ownership". Each person enters the sexual relationship for THEIR OWN SEXUAL ("self-centered") satisfaction AS WELL as to give pleasure to their mate. This idea of marital sex not being at all selfish is nonsense, to put it politely.
And here you assume that one can seperate lust from the act? My friend, if there is no lust why is the act needed in the first place?
If by "lust" you mean, sexual arousal, of course, masturbation is a means of expressing or enjoying sexual arousal. But that's not the meaning of "lust", which is a desire for an evil or forbidden thing, such as lusting to have sex with another man's wife. Masturbation is usually just a desire for [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse], not for a sinful sexual act. The fantasy, if there is one, should not be perverted. Sex and [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse] are regarded as needs for males, and [bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse][bless and do not curse] is a need for all post-adolescents in terms of hormonal balance. We don't know about the sex life of Jesus, so that is irrelevant.
