'Sexual' in the Bible

It is widely reported that there is sexual immorality among you, and the kind of sexual immorality that is not even tolerated among the Gentiles—a man is living with his father’s wife.

I wrote to you in my letter to have no company with sexual sinners;

yet not at all meaning with the sexual sinners of this world, or with the covetous and extortioners, or with idolaters; for then you would have to leave the world.

But as it is, I wrote to you not to associate with anyone who is called a brother who is a sexual sinner, or covetous, or an idolater, or a slanderer, or a drunkard, or an extortioner. Don't even eat with such a person.

“Food for the stomach and the stomach for food,” but God will do away with both of them. The body is not for sexual immorality but for the Lord, and the Lord for the body.

Run from sexual immorality! “Every sin a person can commit is outside the body.” On the contrary, the person who is sexually immoral sins against his own body.

Now with regard to the issues you wrote about: "It is good for a man not to have sexual relations with a woman."

But because sexual immorality is so common, each man should have his own wife, and each woman should have her own husband.

A husband should give to his wife her sexual rights, and likewise a wife to her husband.

Do not deprive each other [of marital rights], except perhaps by mutual consent for a time, so that you may devote yourselves [unhindered] to prayer, but come together again so that Satan will not tempt you [to sin] because of your lack of self-control.

But if they do not have self-control, let them get married. For it is better to marry than to burn with sexual desire.

Let us not commit sexual immorality as some of them did, and in a single day 23,000 people fell dead.
