Are there any established religions that explicitly support homosexuality?

Question

According to scripture Judaism doesn't support gay marriage. Christianity is similar. Hindiusm talks about people born with out gender parts and therefore being 3rd gender but doesn't accept homosexuality. Buddhism says nothing about gay marriage or 3rd genders. Islam also is against homosexuality.

I would like to refrain from talking about intersex people (people born without sexual organs or both male and female organs), because these are incredibly rare compared to actual homosexuality, and, as outlined in Hinduism, are considered to be an exception. Chinese religions like Taoism and Confucianism say nothing about homosexuality.

Are there any religions that are both established (implying that they are relatively old, but still practiced) and explicitly support homosexuality?

Answer 1

In Greek Mythology, Zeus is said to have fallen in love with Ganymede, a kouros, per his beauty. Zeus abducts him to serve as his cup bearer in Olympus. The story has strong homosexual implications, but no one judged Zeus over it, which indicates there was no stigma.

Answer 2

Homosexuality was practiced by the ancient Greeks and Romans as well as ancient Sumerians, Babylonians and Assyrians. Although condemned in the the Bible, the Old testament mentions that prostitutes and transvestites practiced their business in the Temple of Solomon at Jerusalem and dedicated the money they earned toward the temple's upkeep. The American Indians practiced homosexuality, calling men who behaved like women, squaw men, they wore women's clothes and did women's chores.
