To avoid sexual immorality, men must be disciplined in sight and touch. Looking at a woman you’re not married to lustfully or touching her anyhow is sin before God.
“I made a covenant with mine eyes; why then should I think upon a maid?” – Job 31: 1
“But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.” – Matthew 5: 28
“Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman. Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband.” – 1 Corinthians 7: 1-2
