DHK, again we will have to agree to disagree. I believe Heb 2:14-18 makes it abundantly clear that he shared our nature.
Heb 2:14-18 Forasmuch then as the children are partakers of flesh and blood, HE ALSO HIMSELF LIKEWISE TOOK PART OF THE SAME; that through death he might destroy him that had the power of death, that is, the devil: And deliver them who through fear of death were all their lifetime subject to bondage. For verily he took not on him THE NATURE of angels; BUT HE TOOK ON HIM THE SEED OF ABRAHAM. Wherefore IN ALL THINGS it behoved him TO BE MADE LIKE UNTO HIS BRETHREN, that he might be a merciful and faithful high priest in things pertaining to God, to make reconciliation for the sins of the people. FOR IN THAT HE HIMSELF HATH SUFFERED BEING TEMPTED, he is able to succour them that are tempted.
Jesus did not take on the NATURE of angels, but the seed of Abraham. It also says IN ALL THINGS it behoved him to BE MADE LIKE UNTO HIS BRETHREN.
Jesus had the same nature as you and I, if we are born with a sin nature, then so was he.
However, if he was born flesh with lusts and desires, but never obeyed them when it would cause him to sin, then he was not a sinner. The difference is the rest of us obey our lusts and desires and sin.
