Sexual activity in Leviticus 18 - 20 and Romans 1
While same-gender sexual activity does take place in those 4 chapters, not at bit of it is actually homosexuals committing it.
The Canaanites, called "Phoenicians" in History books and encyclopedias, worshipped the fertility goddess "Astarte [also known as Asherah]
Astarte is another Semitic name for "Easter" (aka Eostre - the goddess of Spring) and "Ishtar."
The sexual activity which took place in Leviticus chapters 18 through 20 did not take place in one's home or in private by consenting adults. It was in an outdoor grove of trees (the meaning of 'Asherah' also means 'grove'), at a shrine, or in a pagan temple of worship.
The Hebrews/Israelites/Jews called any person who was in service to LORD God or a pagan god, a "KDSh" (kadesh, kedesh, Kadosh, kodesh, etc. -same spelling no matter what the pronunciation). The Hebrew consonants, K, D, Sh*, together was the root verb, to "be holy," to "sanctify," to "serve a holy purpose, to "be a saint." Hebrew does not actually have vowels and the vowel points which you see in modern Hebrew Bibles were not in the original text and had not even been invented yet when Jesus was ministering in the Holy Land.
When "KDSh" appears in the Hebrew Text and it refers to a "holy" Canaanite priest, the translators of the King James Version of the Bible mis-translated that as "sodomite." But, in the Hebrew language Bible, there is no word that even means "sodomite." When the "holy" person is female, she is a KDShH (kadeshah); the KJV translators do not call her a "sodomitess" but a "whore."
The King James translators also mistranslated "KDSh" when it meant a pagan place of worship or a pagan idol.
The Bible never says what religion the residents of Sodom practiced. Sodom was not in the country of Canaan (which was West of the Jordan River); it was in the geographical area called "The Plain of Jordan." Remember Lot moved from Canaan to the Jordan Plain, East of the Jordan River; and his uncle, Abraham, stayed in Jordan? All of the little city states in "Jordan" had their own kings.
Now back to the subject of the Canaanite worship of false gods:
The sexual activity which took place in those 3 chapters of Leviticus were for heterosexual reproduction and that was the purpose of the rituals. A man who had to be in a heterosexual relationship went to a holy place of worship to sacrifice to Astarte or her male cohort, "Ba'al" (which means "husband -as in the boss of the family") aka Milcolm, Malcolm, Molech, or Molek.
When a heterosexual man in worship of Astarte performed a sacrifice of his "seed" aka "sperm" in a fertility ritual, he either masturbated over an altar fire or he had sex with the male or female holy person in the place of worship. If he had sex with the male person, the male person representing the goddess dressed up in female drag. When the worshipper had sex with the "holy" man, it was not a man having sexual intercourse with another man, it was a man having sex with a male (holy-person) as though the male was a female, therefore, "spiritually" speaking, it was a man having sexual intercourse as with a woman.
In Romans 1, the sexual activity there was for the same reason, worship of fertility gods and goddesses. The women in that chapter were not women having sexual activity with each other, it was women "priestesses" putting on male phallic devices, pretending to be male and using that device with a male worshipper.
Women did not normally go to fertility temples. Why? Because even the Romans believed just like the Canaanites, the Israelites and all of the rest of the known world (even until a microscope was invented), only a man had "seed" before being a parent while a woman only had "seed," aka offspring, after the birth of a child. A woman was only an incubator and the man's seed had a fully formed miniature baby in the head of his sperm.
But, we who have studied high school biology know that it takes both a male gamete (sperm) and female gamete (ova) to make a "seed" or a "fertilized egg."
