Immortalgender is a xenogender with feelings of immortality, almost vampire or god-like feelings. it has strong masculinity and androgyny, which ranges and varies. it is unending and unknowable.
Another way to describe this identity is not quite having a set gender or identity you fit in with but wishing to be seen by others as masculine.[1]
Coined by tumblr user vampire-overlord in 2021, this is a recent term and therefore not very widely used. Of course, everyone is free to identify as this :)
