1 Corinthians 7:3-5

3 The husband should meet his wife's sexual needs, and the wife her husband's.

4 The wife's body doesn't just belong to her, but her husband; and similarly the husband's body doesn't just belong to him but his wife.

5 So don't deprive each other, except by mutual consent for a while— for example because you want to spend time in prayer. Afterwards be together again so that Satan won't tempt you to sin because of your lack of self-control.
