1 Corinthians 7:2

7:2 But because of immoralities, each man should have relations with his own wife and each woman with her own husband.

1 Corinthians 7:5-9

7:5 Do not deprive each other, except by mutual agreement for a specified time, so that you may devote yourselves to prayer. Then resume your relationship, so that Satan may not tempt you because of your lack of self-control. 7:6 I say this as a concession, not as a command. 7:7 I wish that everyone was as I am. But each has his own gift from God, one this way, another that.

7:8 To the unmarried and widows I say that it is best for them to remain as I am. 7:9 But if they do not have self-control, let them get married. For it is better to marry than to burn with sexual desire.

1 Corinthians 7:28

7:28 But if you marry, you have not sinned. And if a virgin marries, she has not sinned. But those who marry will face difficult circumstances, and I am trying to spare you such problems.

1 Corinthians 7:36

7:36 If anyone thinks he is acting inappropriately toward his virgin, if she is past the bloom of youth and it seems necessary, he should do what he wishes; he does not sin. Let them marry.

Matthew 19:12

19:12 For there are some eunuchs who were that way from birth, and some who were made eunuchs by others, and some who became eunuchs for the sake of the kingdom of heaven. The one who is able to accept this should accept it.”
