<< thanks for the comments however you did not state where in the bible it said such fact... >>
I can probably get you a loooooong list with all the passages that talk about it, but that's what google is for. If you want to find more, go check out google, or better yet, grab an actual Bible and read through it. That way you never have to go by what someone else's reading or interpretation is, you can read it for yourself.
For starters:
<<
1 Corinthians 6:18-20 & 1 Corinthians 7:1-2
"Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body. What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's. Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman. Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband." >>
Note that it says every man should have his own wife, and every woman her own husband -- not a husband and a husband or wife and wife.
The sin of fornication is not only defined as illicit sexual intercourse between those who are not married but also is an umbrella for other sexual sins as well. The Bible also speaks of the sin of incest as fornication in
<< 1 Corinthians 5:1: "It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father's wife." >>
<< Revelation 21:8: But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death. >>
Again, you don't have to believe the Bible at all, that's up to each person to decide. But if you choose to believe the Bible, there is absolutely no doubt that any kind of homosexual activity is an 'abomination' against God and therefore a sin. Period.
