The Bible tells us in Proverbs chapter 5 verse 1 to 11
1 My son, attend unto my wisdom, and bow thine ear to my understanding: 2 That thou mayest regard discretion, and that thy lips may keep knowledge. 3 For the lips of a strange woman drop as an honeycomb, and her mouth is smoother than oil: 4 But her end is bitter as wormwood, sharp as a twoedged sword. 5 Her feet go down to death; her steps take hold on hell. 6 Lest thou shouldest ponder the path of life, her ways are moveable, that thou canst not know them. 7 Hear me now therefore, O ye children, and depart not from the words of my mouth. 8 Remove thy way far from her, and come not nigh the door of her house: 9 Lest thou give thine honour unto others, and thy years unto the cruel: 10 Lest strangers be filled with thy wealth; and thy labours be in the house of a stranger; 11 And thou mourn at the last, when thy flesh and thy body are consumed,

Let me share with you a description ory how fulfilling sexual relationship can be within the boundaries of marriage in Proverbs chapter 5 verse 15-23
15 Drink water from your own cistern,
running water from your own well.
16 Should your springs overflow in the streets,
your streams of water in the public squares?
17 Let them be yours alone,
never to be shared with strangers.
18 May your fountain be blessed,
and may you rejoice in the wife of your youth.
19 A loving doe, a graceful deer—
may her breasts satisfy you always,
may you ever be intoxicated with her love.
20 Why, my son, be intoxicated with another man’s wife?
Why embrace the bosom of a wayward woman?
21 For your ways are in full view of the Lord,
and he examines all your paths.
22 The evil deeds of the wicked ensnare them;
the cords of their sins hold them fast.
23 For lack of discipline they will die,
led astray by their own great folly.
