Is sex a sin?

Yes, sex is from Satan. No sex in heaven. I must warn you, there will be plenty of sex in hell. Satan promised me 50.000 sex demons!

English researchers surveyed the sexual frequency of 918 reasonably healthy male residents of the Welsh village, Caerphilly, who were 45 to 59 when the study began (1979-83). A decade later, they checked back with the men, when they were aged 55 to 69. Of the group studied, 150 had died—67 from heart attack and 83 from other causes. The researchers then correlated the men’s sexual frequency as reported in the original survey with their death or survival 10 years later. Compared with men who had had sex just once a month, those who reported having it twice a week had only half the death rate. For the entire group, as an individual's sexual frequency increased, his risk of death decreased.

Fornication and adultery are.

Why? Because the soul is violated, the bible makes it clear that fornication, or sexual act outside of marriage violates the soul of a person.

What does this mean?

Your value is diminished, self value compromised, especially when that person makes no covenant with you or goes to another person.

The Bible commands us to have sex

Genesis 1:28:

"And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it..."

Genesis 9:1:

"And God blessed Noah and his sons, and said unto them, Be fruitful, and multiply, and replenish the earth."

Yeah, that...plus without sex we go extinct.

Plus, it feels great.

Is sex a sin? To some people.

Do you mean sex at 'all or sex outside marriage?

Obvious reasons/circumstances, would be some such as,

Outside of marriage,

Pregnancy, dangerous to a woman, and a child can be costly.

Sure one can argue birth control exists,

. . . But I'm not going to complain about someone saying it's a sin to stab other people with knives, just because we can invent body armor, so stabbings no longer release our blood and life.

. . . Even 'with birth control, lot of people are careless, get pregnant anyway, can have negative life consequences, sometimes too early in life for some people.

Children are a big responsibility, to the kids one is responsible, to society that the kids later act within and upon.

Some partners are not right people one ought have and raise a child with.

Drinking while driving is bad, even if one does not hit another, perhaps.

. . .

Sex, can also spread disease STDs.

. . .

Possibly it can be seen in similar way some people view gambling and drinking.

Often an extreme focus for humans, pleasure above duty and rightness. Excess. Wasting of money above family or helping people.

Compulsive, addicting habit for some.

Plus, it feels great.

...and when it's sinful, it feels even better.

Yes, 

studies show a correlation between regular sexual activity and a longer life due to several factors, including reduced stress, improved cardiovascular health, and lower risks for certain cancers. The positive effects are linked to physical benefits like better immune function and cell health, as well as the mental and emotional benefits of intimacy and relationships. 

You didnt even use the right verses. That was commandment to adam and noah/his family respectively.

1 corinthians 7:1-5

1 Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman.

2 Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband.

3 Let the husband render unto the wife due benevolence: and likewise also the wife unto the husband.

4 The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife.

5 Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency.

Also you can refuse to have sex. But its not for everyone.

1 corinthians 7:7 For I would that all men were even as I myself. But every man hath his proper gift of God, one after this manner, and another after that.

8 I say therefore to the unmarried and widows, it is good for them if they abide even as I.

9 But if they cannot contain, let them marry: for it is better to marry than to burn.

Jesus himself talked about this

Matthew 19:10 His disciples say unto him, If the case of the man be so with his wife, it is not good to marry.

11 But he said unto them, All men cannot receive this saying, save they to whom it is given.

12 For there are some eunuchs, which were so born from their mother's womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven's sake. He that is able to receive it, let him receive it.

Yes, I did.

1 corinthians 7:1-5

1 Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman.

3 Let the husband render unto the wife due benevolence: and likewise also the wife unto the husband.

4 The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife.

5 Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency.

9 But if they cannot contain, let them marry: for it is better to marry than to burn.

That's all Paul, and the consensus of biblical scholars is that when it comes to sex, Paul had issues and needed therapy.

Jesus himself talked about this

Matthew 19:10 His disciples say unto him, If the case of the man be so with his wife, it is not good to marry.

11 But he said unto them, All men cannot receive this saying, save they to whom it is given.

12 For there are some eunuchs, which were so born from their mother's womb: and there are some eunuchs, which were made eunuchs of men: and there be eunuchs, which have made themselves eunuchs for the kingdom of heaven's sake. He that is able to receive it, let him receive it.

Well yeah, when Jesus heard his disciples quote Paul, he was saying, "Oh no, don't listen to Paul on that, that definitely wasn't for us, he has no command of the Lord on that, he didn't mean us, he was actually talking to...ummm...eunuchs, yeah, that's it, eunuchs, he was talking about eunuchs.

Rethinking Extramarital Sex Through a Biblical Lens

When it comes to the ethics of extramarital sex, many Christians default to the idea that the Bible clearly prohibits all sexual activity outside of marriage. But a closer look at Scripture reveals a more nuanced picture—one that invites reflection rather than rigid assumption.

1. Lust vs. Desire

Jesus taught that lust is sinful: “But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart” (Matthew 5:28). The Greek word translated “lust” is epithumeō, which often carries the meaning of covetousness or inordinate desire—a grasping attitude that treats others as objects of gratification rather than persons made in God’s image.

Importantly, the context of Jesus’ teaching is adultery, not just any unlawful or disordered sexual desire. If Jesus had meant all forms of sexual desire outside of marriage, He likely would have said so more broadly. But here, He’s specifically intensifying the commandment against adultery by showing that the desire itself—if indulged—is already spiritually adulterous. In other words, just because someone doesn’t physically commit the act doesn’t mean their heart is clean. The implication is: “You didn’t technically commit adultery with your body, but you would have if you could have.” It’s about disordered intention and inward desire, not merely outward action. Jesus is exposing the deeper heart-level corruption that the law alone couldn’t fully address

Importantly, not all sexual desire falls under this category. Desire itself is not condemned in Scripture—only desire that disrespects boundaries or lacks love and covenant. This suggests that some forms of premarital sexual attraction or activity may not be inherently sinful, depending on the heart, context, and relational integrity involved.

2. What Fornication Really Means

Paul often warns against “fornication,” translated from the Greek porneia (e.g., 1 Thessalonians 4:3). Yet this term historically referred not simply to “sex before marriage” as we define it today, but more broadly to unlawful or exploitative sexual acts, such as incest (Leviticus 18), temple prostitution, adultery, and abuse.

The Bible does not explicitly define porneia as all premarital sex. Instead, it condemns sexual relationships that violate divine order, justice, or covenant. So while premarital sex might sometimes fall under this category, it isn’t automatically equated with porneia in the biblical text.

3. Becoming One Flesh

Genesis 2:24 says, “Therefore a man shall leave his father and mother and be joined to his wife, and they shall become one flesh.” Paul reaffirms this in Ephesians 5:31, applying it to the sanctity of marital union. Sex is portrayed here as something deeply unifying—both physically and spiritually.

But does “one flesh” only apply to marriage? Paul writes in 1 Corinthians 6:16: “Do you not know that he who unites himself with a prostitute is one with her in body?”—clearly showing that becoming “one flesh” can occur even outside the marriage covenant. Rather than proving such sex is sacred, Paul’s point is that sex has profound consequences, whether marital or not. This supports the idea that sex is never casual or meaningless—but it also shows the Bible acknowledges the spiritual impact of sex beyond marriage.

4. Marriage as a Remedy, Not a Requirement

Paul writes: “But because of the temptation to sexual immorality, let each man have his own wife and each woman her own husband” (1 Corinthians 7:2). Here, Paul is addressing a practical issue in the Corinthian church. His advice seems pastoral more than doctrinal: if you can’t remain celibate, marriage is a good, stabilizing path.

He adds in verse 9: “But if they cannot exercise self-control, they should marry. For it is better to marry than to burn with passion.” Yet, he doesn’t define what “burning with passion” precisely means—whether it’s lust, general desire, or emotional longing. Nor does he say that those who “burn” and don’t marry are thereby sinning. He simply offers a wise way to live in wholeness, recognizing human weakness and need.

5. What the Bible Doesn’t Say

Despite centuries of strong teaching against premarital sex, it’s striking that no verse explicitly states that all sex before marriage is a sin. This silence is significant. While the Bible is clear about the sacredness of sex and the dangers of lust, exploitation, and adultery, it never directly declares consensual, loving premarital sex as morally forbidden.

The same can be said of masturbation—a topic not directly addressed in any moral or legal prohibition in Scripture. Though often condemned by tradition, the biblical texts don’t weigh in definitively.

6. Conclusion: Walking Carefully

To be clear, this isn’t a free pass to treat sex casually. Scripture consistently upholds sex as sacred, relational, and spiritually powerful. It warns against selfishness, exploitation, and anything that dehumanizes. But within that framework, the biblical witness may be less rigid than often assumed.

Yes, many would argue the implication of Scripture is that sex belongs within marriage—and that’s a reasonable interpretation. But it’s equally fair to note that the lack of explicit condemnation invites thoughtful dialogue and discernment. Especially when love, honesty, and mutual respect are present, we may need to look beyond blanket rules and ask: What kind of relationship honors the image of God in both people?

The reason those sins (incest, prostitution, adultery, etc.) are condemned is because the sex is non-marital.

“Or know you not, that he who is joined to a harlot, is made one body? For they shall be, saith he, two in one flesh.”

The Bible doesn’t want sex to be casual. Harlots engage in “casual” sex, but sex with a harlot is not casual. Sex is for marriage because marriage is a bond.

No.

Sex is basically a procreational process, intelligently evolved into a recreational exercise.

Sin is a repressive concept or an evolved state of mind relative to the above.

And religion is largely bunkum and an excuse for repressive concepts.

I'm thinking most 'everyone has ideas of right and wrong, even atheists.

Even the areligious can arguably have ideas of right and wrong regarding sex in various circumstances.

You seem a lot more negative about religion these days.

Well, "religion" is something of a general term.

Though I am perhaps "negative" in my appreciation of fairly recent mythical and magical creation and existence hypotheses.

Especially one's that coincidently assume the authority to dictate social policy.

Right and wrong are concepts relative to social development, and some such concepts become established principles.

Though established principles are easily ignored, even by the most devout amongst us.

I'm thinking most 'everyone has ideas of right and wrong, even atheists

Atheists have subjective morality, and that is basically "anything goes" morality.

Sin is a monotheistic concept. Most pagan, religions work on a chaos/ order dynamic. Most roles on marriage/ sex in pagan cultures are more a matter of the culture, than the religion.

You raise more questions than answers about extramarital sex. The fact that Jesus surrounded himself with 12 men proves his biased views.

No.

Sex is basically a procreational process, intelligently evolved into a recreational exercise.

Do you really think animals fuck one another in order to procreate? No, they don't. They have sex because it's filthily delicious. Just see how a horse neighs when it reaches orgasm.

I asked if sex is a sin in a moral sense rather than in a biblical interpretation. Sex per se is not bad at all, what it's bad though is that in order to get it you have to make someone else suffer from it. I guess marriage was created for that, in order to protect the family created because we all know there are people that are so fucking weak that can abandon their families only for having as much sex as they can with someone else.

I'm convinced that if there are people that are ok to have multiple sexual partners, sex in this context would be utterly ok. For example, swingers are cool doing what they do, and much to my delight, that's completely fine. 😂

Sex is perhaps the most difficult carnal desire to control. I believe religions set up draconian rules about sex in a vain attempt to tame human beings. I like sex a lot but I can control it. I've never, ever, made a woman suffer because of that, and not precisely thanks to a fkn religion. So, I think religions failed misserably to stop human beings from losing their minds for sex.

Yes, sex is from Satan. No sex in heaven. I must warn you, there will be plenty of sex in hell. Satan promised me 50.000 sex demons!

No wonder I called myself IL DIAVOLO. 😁

A guiding star is a guiding star,

And limits are limits.

Of Nature and Nurture Values develop, and get held to.

Laws arise whether Individual's Lines, or Collective Agreements.

By Habit they burrow and hold fast.

They can change I admit,

Though there are 'versions of chess,

Specific versions can be identified and played primarily.

Some people turn to murder and cannibalism when there's no other food but people around.

But people 'still have parameters.

Ideas of Right and Wrong.

Subjective or not, they're not 'so subjective for most people that they change in a breath.

. . .

Is sex a sin?

I say yeah, to some people, no to others, depending on their values, even if they're Atheists,

Because even Atheists have values.

Doesn't matter if those values might shift 'eventually,

Various theoretical Moral and Ethical Frameworks exist.

. . . It's a bit like saying does 3 go into X?

Because there are multiple frameworks, the answer is yes and no.

Some frameworks are X as 2,

Others X is 3 or 9.

Just depends.

Atheists 'still hold to frameworks.

And often call various actions Right or Wrong within said frameworks.

@#18

I have heard of the Law of Hospitality in various Pagan Religions before.

The value of Oaths.

Kinslaying.

I'm not sure if Ancient Greeks or Norse might have different words for sin,

But the concept seems 'roughly the same?

Wrongdoing, missing the mark, crime, taboo, sin.

I don’t think animals have sex for any reasom.

Do you think animals have reasons for anything they do?

It’s just instinction. I’d say procreation, but I don’t think they’re really thinking it. They don’t do it because they like it.

Some animals seem more intelligent to me than others,

Elephants, dolphins, chimps, border collies, cuttlefish.

Compared to a a grasshopper for instance.

Instinct, Nature vs Nurture,

Even a human will not develop as much locked up in a room or left alone as a feral child.

I assume animals become more or less intelligent depending on how they are nurtured.

They might have different levels of smartness, but none compare to humans.

Heh, I'd agree I don't rate other animals intelligence as high as educated socialized adult humans with access to past stored information.

Though I'm not sure how to define intelligence and reason.

Arguably animals intelligence can be compared to humans, just that when comparing the two, we rate animals lower?
