Loki turned into a mare to get properly fucked by a stallion, get pregnant and deliver an 8 legged super horse (Sleipnir) that Odin proudly rode around... yeah, they are very fine with gender fluidity

cal tradition known as seidr, of which Odin and Freya are the foremost divine practitioners. In traditional Germanic society, for a man to engage in seidr was effectively to forsake the male gender role, which brought considerable scorn upon any male who chose to take up this path. As the sagas show, this didn’t stop some men from practicing seidr anyway. However, even Odin wasn’t exempt from such charges of “unmanliness,” and was taunted for adopting the feminine traits and tasks that form part of the backbone of seidr. Saxo, in the passage on Odin’s exile alluded to above, relates that “by his stage-tricks and his assumption of a woman’s work he had brought the foulest scandal on the name of the gods.”[16] Note also the reference to being “fertilized” in the verse quoted above – while this is certainly a metaphor, it’s a metaphor loaded with sexual implications that would have been immediately recognizable to any Viking Age or medieval reader or hearer of the poem.
