Sinful, well, maybe it depends on how one views sin, and maybe the nature of the sex toy (I would imagine ones designed for more than two people to use would probably be a bit questionable). But I don't honestly recall any biblical verse which states that only 1 sex position can be acceptable or that inanimate objects can't get in on it.
Is using sex toys a sin? Though using these items is not specifically stated as a sin in the Bible, it could be argued that this is sinful due to lust and unnatural that it is sinful.
Most sex toys (not all by any means) are really masturbatory in nature. They help you have an orgasm. Now, like I said, orgasms are great! But if sex toys are allowing you both to avoid doing some serious work in your sexual and emotional relationship that needs to be done, then they’re actually detracting from intimacy.
Q. I've recently become a Christian and now I'm praying that my husband will, too. We've had a rocky marriage, but the most stable part of it has been our sex life. Unfortunately, our sex life was pretty adventurous, involving toys and some porn. Now I'm trying to get up the nerve to tell him I don't want to do those things anymore.
Marital sex is part of a healthy relationship. It’s not something to be manipulated for its own sake or for the sake of one partner’s personal pleasure. So, what about sex toys? The Bible never addresses the question of sex toys or “marital aids” — so we’d suggest (tentatively) that couples use their own judgment.
While it’s not clear that this is a sin to use, many Christians feel they are bringing someone else into their marriage bed. If an item is not advertised as being modeled after someone, it’s just a generic sculpture. If a sex toy is used, it should bring the couple closer and/or result in one or both of them enjoying sex more.
The answer to question two, any kind of sex, intercourse or oral sex is prohibited before marriage. God doesn’t say in so many words, “Thou shalt not have sex before thou art married,” but in Genesis 2:24, he says, “For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh.”.
Masturbation is not stated to be sin, yet it's hardly God's best for us. Also, I was very heartened to hear you speak out against sex-toys: these things can really mess up a woman's sexual response very badly, and ruin intimacy with her husband (or future husband).
Sex is not a dirty word and it should be talked about more… especially in the church. Here are 5 lies that single Christians should refuse to believe about their sexuality.
If a husband and wife both agree that they want to try something (e.g., oral sex, different positions, sex toys, etc.), then the Bible does not give any reason why they cannot. There are a few things, though, that are never allowable sexually for a married couple.
