Rest assured that your sin must be atoned for. If you are truly "Born Again", with Christ in you, you will understand more fully. If you take this one verse and say, self-mutilation is proper, then you don't understand that God does not encourage one sin over another. Christ died for your all of your sins. God does not require you to physically die for your sin or literally hurt yourself, but to spiritually die to your sin, meaning, if you accept Jesus Christ as your personal savior, then you receive the gift of salvation, where by, Jesus paid the penalty. Jesus said: “You have heard that it was said, ‘You shall not commit adultery.] 28 But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart. Matthew 5-27,28
If you believe in the literal "plucking out of the eye" verse, then how can you, in the incident of this form of adultery, pluck out the one eye , with out plucking out the other, it makes no sense. What makes sense, is that we sin in ways we don't even understand and the truth and you answer to this deli-ma, is to, in earnest ask Jesus to come into your heart and receive his forgiveness, for which he has already provided.
