It’s episode number 400. Such a milestone should be marked with an epic episode. You ask the questions, I offer them to Pastor John, and he answers them. That’s how it works on the Ask Pastor John podcast. We get a lot of questions about relationships, dating, marriage, and, of course, sex. And that leads to episodes that may not be suitable for all listeners, and are really designed to be listened to by married couples. Such is the case today. In the last month, ten questions have arrived on the question of oral sex. The question is always the same: Pastor John, is this practice permissible in a Christian marriage, or is it always sinful?

Questions relating to sexual intimacy should, I think, be handled with what you might call verbal modesty, rather than shocking or crass words. I think dressing and talking in immodest ways are both wrong. So that is kind of governing some of my language now. These are real concerns. I am okay with this question. It is a little bit difficult and sensitive, but it is okay. People want biblical guidance, and so here is my effort at biblical wisdom.

Married Couples Only

First of all, I am assuming the question is only relating to people who are married when I give this counsel. I think it is wrong outside marriage. And we can talk about that another time more extensively.

But here is the short answer why: oral sex is even more intimate and delicate, it seems, than copulation. And we know this because even married couples are wondering if they should go there. It is as if it is a stage of intimacy that may not even be proper for married people.

And so to think it can be an innocent substitute for copulation, so people can obey the letter of the law outside marriage, is a mirage. That is the first observation.

Four Principles for Considering Oral Sex

In marriage, here is what I would say. If oral sex is wrong, I can think of four possible reasons it would be wrong. I will name them and then I will ask this question: Do those four things exist?

It would be wrong if it were prohibited in the Bible. It would be wrong if it were unnatural. It would be wrong if it were unhealthy — that is, harmful. It would be wrong if it were unkind.

So let’s take those one at a time.

1. Does the Bible forbid oral sex?

I don’t think oral sex is explicitly prohibited in any biblical command. If the Bible proscribes it, it would have to be by principle, and not by an explicit command.

2. Is oral sex unnatural or unfitting?

Is it unnatural? This is a tricky one. The male and female genitals are so clearly made for each other, that there is a natural fitness or beauty to it.

What about oral sex? Now you might jump to the conclusion and say, “No, that is not natural.” But I am slow to go there because of what the Proverbs and the Song of Solomon say about a wife’s breasts. This is kind of an analogy. So consider this: It seems to me nothing is more natural than a baby snuggling in his mother’s arms, drinking at her breast. That is what breasts are. They are designed to feed babies.

So is there anything physically natural about a husband’s fascination with his wife’s breasts? Well, you might say no, that is not what breasts are for. But Proverbs 5:19 says, “Let her breasts fill you at all times with delight; be intoxicated always in her love. And Song of Solomon 7:7–8 are even more explicit, speaking of the woman: “Your stature is like a palm tree, and your breasts are like its clusters. I say I will climb the palm tree and lay hold of its fruit. Oh may your breasts be like clusters of the vine.”

Well, even though there is very little anatomical correlation between a man’s hands or his lips and his wife’s breasts, it surely seems to be “natural” in another way — namely, built-in delight and desire that God, in his word, seems to commend for our marital enjoyment. So I ask: Might there be similar desires for oral sex or other kinds of sex? So I doubt that we should put a limit on a married couple based on the claim of it being unnatural. That is risky, but that is where I come down on the naturalness of it.

3. Can oral sex be unhealthy or harmful?

Is it unhealthy or harmful? Well, it certainly might be if there are any sexually transmitted diseases present. And it could be performed in harmful ways. And so, the couple needs to be very honest and caring by not taking risks that would be unloving.

4. Is oral sex unkind?

Which leads to the last question: Is it unkind? Now I think this one is probably the one that touches the rawest nerve and the one that has the greatest impact. Will you pressure your spouse for oral sex if he or she finds it unpleasant? If so, then you are unkind, and it is a sin to be unkind. Ephesians 4:32 says, “Be kind to one another.” But the key word here is pressure.

I know that 1 Corinthians 7:4 says, “The wife does not have authority over her own body, but the husband does. Likewise the husband does not have authority over his own body, but the wife does.” And the context there is sex. So what does that mean, practically? It means that both the husband and the wife have the right to say to the other, “I would like to [fill in the blank]. And both of them have the right to say, I would rather not [fill in the blank]. And in a good marriage, the biblically beautiful marriage, both of them seek to outdo the other in showing kindness.

So those are my principles, Tony, that would guide the Christian couple in this matter of oral sex.
