1 Corinthians 6:9 Know you not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, 10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God. 11 And such were some of you: but you are washed, but you are sanctified, but you are justified in the name of the Lord Jesus, and by the Spirit of our God.

Or in the Net Bible is even more clear:
1 Corinthians 6:9 Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived! The sexually immoral, idolaters, adulterers, passive homosexual partners, practicing homosexuals, 10 thieves, the greedy, drunkards, the verbally abusive, and swindlers will not inherit the kingdom of God

Romans 1:21-28 21 Because, when they knew God, they did not glorify Him as God, neither were thankful; but they became vain in their imaginations, and their foolish heart was darkened. (The Sin)
22 Professing themselves to be wise, they became fools,
23 And changed the glory of the incorruptible God into an image made like to corruptible man, and to birds, and four-footed beasts, and creeping things.
24 Therefore God also gave them up into uncleanness through the desire for forbidden things that is within their own hearts, to dishonor their own bodies between themselves (The Punishment)
25 Who changed the truth of God into a lie, and worshiped and served the creature more than the Creator, who is blessed into the eon. Amen.
26 For this cause God gave them up to vile affections: for even their women did change the natural use into that which is against nature:
27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompense of their error which was necessary [Gr. Dei].
28 And even as they did not like to retain God in their knowledge, God gave them over into a reprobate mind, to do those things which are not convenient;
29 Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
30 Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
31 Without understanding, covenant breakers, without natural affection, implacable, unmerciful:
32 Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in those who do them (they know).

Deuteronomy 23:17 There shall be no whore of the daughters of Israel, nor a sodomite of the sons of Israel

Leviticus 18:22 You must not have sexual intercourse with a male as one has sexual intercourse with a woman; it is a detestable act.

Leviticus 20:13 If a man has sexual intercourse with a male as one has sexual intercourse with a woman, the two of them have committed an abomination. They must be put to death; their blood guilt is on themselves.

I Timothy 1:10 For whoremongers, for those who defile themselves with mankind, for men stealers, for liars, for perjured persons, and if there be any other thing that is contrary to sound doctrine;

Jude 7. Even as Sodom and Gomorrah, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the justice of eonian fire.

When the men of Sodom wanted to have sex with the three angels, Lot said this: "Behold now, I have two daughters which have not known man; let me, I pray you, bring them out to you, and do ye to them as is good in your eyes: only to these men do nothing; for therefore came they under the shadow of my roof." (Genesis 19:4-8) The Hebrew word for "know" in verse 5 is yada`, a sexual term. It is used frequently to denote sexual intercourse (Genesis 4:1, 17, 25; Matthew 1:24, 25).

It helps to understand that God created a specific pattern and order for life. Any variation from that or perversion of it is an abomination. Genesis 1:27, 28 27 So God created man in His own image, in the image of God He created him; male and female He created them.

Matthew Henry's commentary on the Bible speaks of the Seventh Commandment this way: "The seventh commandment concerns chastity. We should be as much afraid of that which defiles the body, as of that which destroys it. Whatever tends to pollute the imagination, or to raise the passions, falls under this law, as impure pictures, books, conversation, or any other like matters."
