There is no contradiction, once you base your argument on doctrine of the origin of sin in man. Unlike Catholicism and its original sin, which is the sin that every human being is born with after the fall, because of Adam's sin. In other words, it is a sin contracted by us not committed, but still you are born a sinner.
Catechism of the Catholic Church; Section Two: I. The creeds; Chapter One I Believe In God The Father; Paragraph 7. The fall
403 Following St. Paul, the Church has always taught that the overwhelming misery which oppresses men and their inclination towards evil and death cannot be understood apart from their connection with Adam's sin and the fact that he has transmitted to us a sin with which we are all born afflicted, a sin which is the "death of the soul".291 Because of this certainty of faith, the Church baptizes for the remission of sins even tiny infants who have not committed personal sin.292
419 "We therefore hold, with the Council of Trent, that original sin is transmitted with human nature, "by propagation, not by imitation" and that it is. . . 'proper to each'" (Paul VI, CPG # 16).
Protestants do not believe that you are born a sinner, but the concept of original sin is that which Adam committed, causing the fall. From which we are all born with a fallen nature, a corrupted and sinful nature. We are born sinful.
Westminster Confession of Faith; Chapter 6, Paragraph 2
By this sin they fell from their original righteousness, and communion with God, and so became dead in sin, and wholly defiled in all the faculties and parts of soul and body.
London confession of faith 1689; Chapter 6, Paragraph 2
Our first parents, by this sin, fell from their original righteousness and communion with God, and we in them whereby death came upon all: all becoming dead in sin, and wholly defiled in all the faculties and parts of soul and body.
And it is for this reason that we are unable to do good (seek God, or fulfill his commandments; Romans 3: 10,11) and inclined to only do evil (follow the designs of our flesh, of our heart, wherever it lead us; Galatians 5: 19-21)
So according to this doctrine, you cannot be born gay or trans or adulterous or pornographic or liar or murderer or greedy, etc, but you are born with a biased nature to do any of these things to get away from God. And it is only through Jesus Christ that we are freed from the slavery of sin. But until the restoration comes, we will continue to struggle with these sins as well as Paul in Romans 7: 14-25, but we must maintain a life that mortify those sins Colossians 3: 1-17
