Hi there Kthespis, you can just reject what all those people told you then. Because they simply don't know what they are talking about.
Get your counsel from the word of God. The Bible has the solution to your dilemma:
1 Corinthians 7:1-2 KJV
Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman. [2] Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband.
1 Corinthians 6:18-20 KJV
Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body. [19] What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? [20] For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's.
Ephesians 5:5-7 KJV
For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God. [6] Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience. [7] Be not ye therefore partakers with them.
2 Timothy 2:22 KJV
Flee also youthful lusts: but follow righteousness, faith, charity, peace, with them that call on the Lord out of a pure heart.
Hebrews 13:4 KJV
Marriage is honourable in all, and the bed undefiled: but whoremongers and adulterers God will judge.
