Proverbs 5:19 (NKJV) — 19 As a loving deer and a graceful doe, Let her breasts satisfy you at all times; And always be enraptured with her love.
God created man and woman to enjoy a full relationship spiritually, socially, and physically. There is nothing wrong with the marital relationship and its physical dimension.
1 Corinthians 7:3–5 (ESV) — 3 The husband should give to his wife her conjugal rights, and likewise the wife to her husband. 4 For the wife does not have authority over her own body, but the husband does. Likewise the husband does not have authority over his own body, but the wife does. 5 Do not deprive one another, except perhaps by agreement for a limited time, that you may devote yourselves to prayer; but then come together again, so that Satan may not tempt you because of your lack of self-control.
Hebrews 13:4 (NKJV) — 4 Marriage is honorable among all, and the bed undefiled; but fornicators and adulterers God will judge.
