i believe stretching your earlobes like that is considered a form of self mutilation which in Christianity is a sin yes.
1 Corinthians 6: 15, 19-20
15 Know ye not that your bodies are the members of Christ? shall I then take the members of Christ, and make them the members of an harlot? God forbid. 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.
