Dating is a one-on-one experience for the most part. You don't want anybody else around because you don't want anyone else to see what you are doing.
A Godly husband protects his wife; a Godly man protects his sister.
If it is a man and they have read the Word they usually quote 1st Corinthians emphasizing the "seek not a wife" part with a pained look on there face.
If anyone can find anywhere in the Word of God that dating as we understand it today is scriptural I would like to see it. That does not mean you can't meet and get to know members of the opposite sex.
Dating before then can lead to immorality, limit the number of other young people you meet, and deprive you of experiences that will help you choose an eternal partner.” Not all teenagers need to date or even want to.
Many young people do not date during their teen years because they are not yet interested, do not have opportunities, or simply want to delay forming serious relationships.
