God has given us a very explicit ruling on homosexuality. Read what His Word says.

46. Thou shalt not lie with mankind, as with womankind: it is abomination. . .Defile not ye yourselves in any of these things: for in all these the nations are defiled which I cast out before you: and the land is defiled: therefore I do visit the iniquity thereof upon it, and the land itself vomiteth out her inhabitants. (Lev 18:22, 24-25).
