By "other" do you mean in Lev 18 which is the chapter in the bible on sexual sins ? Very exact and precise other things we see when reading. Not broad categories, but precise things. And a very complete list. Read and see for yourself. Also, Deu 4:2 instructes not to add anything!
This has interested me for some time, it does seem to prohibit same sex relationships. This is my understanding of it:
Lev 18:9 says "Do not have sexual relations with your sister, either your father’s daughter or your mother’s daughter, whether she was born in the same home or elsewhere."
Lev 20:17 says, "If a man marries his sister, the daughter of either his father or his mother, and they have sexual relations, it is a disgrace. They are to be publicly removed from their people. He has dishonored his sister and will be held responsible."
If this is a law for all time, Abraham was in trouble. Sarah was his half sister, in Genesis 20:12 Abraham says, "...she really is my sister, the daughter of my father though not of my mother; and she became my wife."
So clearly there was a point where these laws did not apply, right? Otherwise Abraham would have to have been removed from the people he was to father! So these cannot be laws that have always applied or be inferred from what God had revealed or created, up to the point that law was given.
This brings us back to the question of whether we as Christians are under the law. Paul says, "the law was our guardian until Christ came that we might be justified by faith. Now that this faith has come, we are no longer under a guardian." (Gal 3:24-25)
He also comments on the law itself, in verse 12 when he says, "The law is not based on faith;
on the contrary, it says, “The person who does these things will live by them.”" He's quoting Leviticus 18:5 to make the point. So he is expressly identifying this chapter with "the law" which we are not under because we live by faith in Jesus, and his finished work on the cross.
So to me, you cannot argue against same sex relationships using Leviticus.
