We’ve gotten enough emails on the topic that it’s worth addressing: is it ok for Christians to engage in swinging or wife swapping? (None of the emails we’ve received are suitable for quotation.) I suppose we get these emails because it’s obvious from our blog that Sexy Corte and I are pro-sex and enjoy some kinky stuff that isn’t discussed at church. I’m not sure if the folks who email us are genuinely wondering what the Bible has to say on swinging or if they’re looking for someone to help rationalize existing behavior, but I’m going to give a sincere answer.

Swinging or wife swapping is a sin called adultery, and is never acceptable to God. It doesn’t matter if you, your spouse, and the other couple all consent — God doesn’t consent. The Seventh Commandment is short and to the point:

Exodus 20:14, “You shall not commit adultery.”

Jesus raises the bar set in the Old Testament:

Matthew 5:27-28, “You have heard that it was said, ‘You shall not commit adultery.’ But I say to you that everyone who looks at a woman with lustful intent has already committed adultery with her in his heart.”

A person might claim, “It’s not adultery if my spouse knows about it and approves.” However, the definition of adultery makes no such distinction, and never has throughout human history.

voluntary sexual intercourse between a married person and someone other than his or her lawful spouse.

The bottom line here is similar to an earlier Q&A on threesomes:

God’s will is that sex should be reserved exclusively for a husband and a wife. So, while there aren’t many limits on what you and your wife can do together, you can’t bring someone else into your sexual relationship. Neither spouse can give the other spouse permission to commit adultery — adultery isn’t just a sin against your spouse, it’s a sin against God. Permission from your spouse doesn’t make adultery acceptable to God. It is never acceptable to have sex outside of your marriage. See also: Proverbs 5, “be intoxicated always in her love”Hebrews 13:4, and Proverbs 7.

If your marriage is happy, swinging won’t strengthen it; if your marriage is unhappy, wife swapping won’t fix any of the underlying problems. We strongly exhort every married couple to keep their sex life exclusive to themselves. This is what God commands through the Bible, and worldly experience says the same thing.

Reader “B” asks:

What are your thoughts on FFM threesomes?

My wife has expressed interest in a FFM threesome where I as the husband would only interact with my wife and she can interact with the other female. We are both Christians and are struggling with this desire. While wanting to pursue this we are also burdened with the sinful nature of it. What are your thoughts regarding this? There has been some girl/girl stuff happen in the past as part of some experimenting while we were married and I was present for it. But we are looking into the swinging lifestyle and have rules and boundaries in place and nothing has happened yet. Wanting another Christians viewpoint on this situation.

As we wrote in our post about sexual boundaries in marriage, God’s will is that sex should be reserved exclusively for a husband and a wife. So, while there aren’t many limits on what you and your wife can do together, you can’t bring someone else into your sexual relationship. Neither spouse can give the other spouse permission to commit adultery — adultery isn’t just a sin against your spouse, it’s a sin against God. Permission from your spouse doesn’t make adultery acceptable to God. It is never acceptable to have sex outside of your marriage. See also: Proverbs 5, “be intoxicated always in her love”Hebrews 13:4, and Proverbs 7.

If that’s not enough, it’s easy to Google for something like “threesome ruined my marriage” and find hundreds of horror stories. Of course, you think your marriage is differentbut everyone thinks that. 93% of Americans think they’re better-than-average drivers. If you and your spouse are currently pretty happy in your marriage, having a threesome is very likely to cause a huge amount of damage. You can read one such story in Genesis 16 and 21, about Abraham, Sarah, and Hagar.

On the other hand, if you and your spouse aren’t happy in your marriage, a threesome won’t fix things. There are a zillion reasons for marital dissatisfaction, but think about it: why would adding a third person to the dynamic strengthen your relationship with your spouse? It may temporarily distract you from the pain and frustration you’re feeling — like becoming an alcoholic — but it won’t resolve any of the problems that are actually causing dissatisfaction. If your marriage is having trouble, drinking more alcohol isn’t likely to improve things… you’ll just self-medicate yourself into oblivion. In the end, you’ll be worse off than you are now. Peruse our blog or any of the links on the sidebar for ideas on how to spice up your sex life with your spouse.

We strongly exhort every married couple to keep their sex life exclusive to themselves. This is what God commands through the Bible, and worldly experience says the same thing.

“B” replies:

Thank you for your response. We have done a lot research and we agree that it is sinful and should not be pursued. That being said, the feelings are still there for us both and that will be a struggle. Our faith was strong when we first got married and there have been bumps in the road but we are both very happy in our marriage and in life. I do struggle in my faith because of my job as a firefighter/paramedic and the stuff I have to see and deal with makes it hard to believe that there’s a God that loves us and watches over us.

It’s good that B and his wife have avoided this sin. It’s common to look at the evil, pain, and death that surround us in the world and wonder why God hasn’t prevented it — but he’s given us the ability to stand against evil by the power of the Holy Spirit. The choices we make can be holy, glorifying to God, and healing to mankind, or they can be selfish and evil. Resist temptation and make good choices! We’re grateful for people like B who put their lives on the line to protect us.
