Sex is God’s invention. He is the mastermind behind it—and His creation is worth far more to Him than it is to us. This beautiful expression of love was created out of His own heart, as a gift to be experienced between a husband and wife. It is only in marriage that this manifestation of intimacy can be fully enjoyed in the depth for which it was created.
“Marriage should be honored by all, and the marriage bed kept pure, for God will judge the adulterer and the sexually immoral” (Hebrews 13:4, NIV).
 ”Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge” (Hebrews 13:4, KJV).
The more beautiful and unique something is (like sexual intercourse), the more power it holds over our lives, either for good or bad influence. That is why it is so easy for the devil to corrupt the most precious of God’s gifts. When we become more in love with the gifts than the One who endowed them, the things that were designed to bless us begin to destroy us instead. Yes, God cares about what we do with our bodies, in public or in private. He doesn’t want us to abuse ourselves in any way.
In fact, an older definition of masturbation is “self-abuse.” Although more modern dictionaries may no longer carry this definition, they are still linked together under self-abuse:
1. Abuse of oneself or one’s abilities.
2. Masturbation.
1 Corinthians 6:18 (NIV) further confirms this, saying that unlawful sexual relations defile our own bodies. “Flee from sexual immorality. All other sins a man commits are outside his body, but he who sins sexually sins against his own body.”
 ”Yes, it is better to masturbate, because at best it corrupts only one person. It certainly is the lesser of two evils.”
