Question: I have recently came across Tu'er Shen, a Chinese deity who manages the love and sex between homosexual men. After reading about him, I am interested to find out if there are any homosexual gods(exclude the Greco-Roman gods), preferably those who married another homosexual god. However, I am not looking for gods who are in charge of homosexual love, like the Chinese god mentioned above, but I am looking for gods who are naturally homosexual, like Zeus, who took Ganydeme, a boy, as a lover.

Answer: 
I believe [this link](https://en.wikipedia.org/wiki/LGBT_themes_in_mythology#Critical_perspective) will be of interest to you. It seems that there are actually very few belief systems / mythologies that DON'T include some form of homosexuality, especially across Asia. Norse and Celtic stories don't make any mention of it, but they don't have any problems with it, as far as I know.
You could, in some ways, look at the events surrounding the conception of Loki's horse-child Sleipnir as an act of homosexuality. Loki tries to stop a frost giant from winning Freya's hand in marriage over a bet to build a wall for the gods of Asgard in the absence of Thor, the Protector. Loki, in order to stop the frost giant just as he is about to finish and win his deserved prize, shapeshifts into a horse and runs off with the giant's impressive horse, Svaoilfair. The story of how Asgard got it's wall ends 9 months later when Loki rides back to the hall of the gods on an 8 legged horse that he then gifts to Odin.

There is some general ambiguity, but this myth does more than hint that Loki conducted some form of a homosexual act. However, it could also not be, as Loki shapeshifts into, presumably, a female horse, as conception would be otherwise impossible (but then again this is Norse mythology...). So potentially, Loki may have been a homosexual god in one way or another.
