Hi'iaka from Hawaii is bi and has relationships with women, most famously Hopoe. In some legends, Ganesh is born from Parvati making Malini drink the oils from her body, which is both gay and fpreg.

It's hard to tell what's historical canon sometimes because there are so many reinterpretations both by queer women reclaiming their deities and by homophobes intent on reframing queer stories as "close friends" or "handmaidens".
