The letters to Romans about homosexuality

Some people claim that apostle Paul in the letter to Romans brought forth heathens licentious homosexual acts, but didn't condemn caring and responsible gay relationships.  This is a false claim.

Ro 1:
24 for this cause, god gave them up to the filthy lusts of their heart, to dishonor their bodies with them.
25 and they changed the truth of god into a lie; and worshipped and served the created things, much more than the Creator of them, to whom belong glory and blessing, for ever and ever: Amen.
26 for this cause, god gave them up to vile passions: for their females changed the use of their natures, and employed that which is unnatural.
27 and so also their males forsook the use of females, which is natural, and burned with lust toward one another; and, male with male, they did what is shameful, and received in themselves the just recompense of their error.
28 and as they did not determine with themselves to know god, god gave them over to a vain mind; that they might do what they ought not,

In the letter to Romans apostle Paul teaches that some females have changed natural sexuality to unnatural sex, in which females have sex with other females (lesbianism), which is a sin. Apostle Paul also teaches that some males forsook natural sex with females and practiced sex with other males (homosexuality), which is a sin. Apostle Paul condemned homosexuality as a sin. In the question was changing natural sex orientation to unnatural sex (homosexuality).

Apostle Paul wrote very clearly that homosexuality (men having sex with other men; women having sex with other women) is a sin. Ro 1:27 is the word error, which is in Greek plane, which means error, to deceive, deceit, one led astray from the right way, error which shows itself in action, a wrong mode of acting. In this place, the Bible in the New Testament shows very clearly that same-gender sex is a sin and aberration from the right way. Apostle Paul taught very clearly that homosexuality is unnatural sin.  

The message is very clear that the Bible in the New Testament condemns same-gender sex. Homosexual orientation is not congenital, people haven't borne with it, but choose it as the choice of a sin. The reason in what way people choose homosexuality are, for example, the distant and cold relation to parents, a man sexually abusing a boy, a woman sexually abusing a girl, negative experiences and ill-usage by opposite gender.

1 Cor 7:2 Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband.

The Bible in the New Testament teaches that avoiding fornication means that every man must have his own wife and every woman must have her own husband. From this place, we also see that the will of God is not homosexual relations.
