The above verses also state the we should confess our sins.  This means that we should not deny the fact that we are all sinners; we shouldn't make claims that we are without sin.

note: There is no mention of you needing to go tell your sins to some other man.

Matt 10:32-33
32 Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven.
33 But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.
(KJV)
 

Luke 12:8-11
8 Also I say unto you, Whosoever shall confess me before men, him shall the Son of man also confess before the angels of God:
9 But he that denieth me before men shall be denied before the angels of God.
10 And whosoever shall speak a word against the Son of man, it shall be forgiven him: but unto him that blasphemeth against the Holy Ghost it shall not be forgiven.
11 And when they bring you unto the synagogues, and unto magistrates, and powers, take ye no thought how or what thing ye shall answer, or what ye shall say:
(KJV)
 

Rom 10:4-13
4For Christ is the end of the law for righteousness to every one that believeth.
5For Moses describeth the righteousness which is of the law, That the man which doeth those things shall live by them.
6But the righteousness which is of faith speaketh on this wise, Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down from above:)
7Or, Who shall descend into the deep? (that is, to bring up Christ again from the dead.)
8But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach;
9That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
10For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
11For the scripture saith, Whosoever believeth on him shall not be ashamed.
12For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
13For whosoever shall call upon the name of the Lord shall be saved.
(KJV)
 

1 Tim 2:5-6
5 For there is one God, and one mediator between God and men, the man Christ Jesus;
6 Who gave himself a ransom for all, to be testified in due time.
(KJV)
 

I Jn 4:14-16
14 And we have seen and do testify that the Father sent the Son to be the Saviour of the world.
15 Whosoever shall confess that Jesus is the Son of God, God dwelleth in him, and he in God.
16 And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him.
(KJV)
 

I Jn 1:8-10
8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
10 If we say that we have not sinned, we make him a liar, and his word is not in us.
(KJV)
 

II Jn 1:7
7 For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist.
(KJV)
