First, I think this post should go into the Otherkin thread rather than the advice thread but regardless, let me try to help you.
Animals are highly receptive. While they don't probably see you as a literal snake, I imagine they do respect you enough to consider you not a threat, much like how snakes view other snakes in their 'family' or whatever. I think they do see you as one of them, but a different member. As for the lack of LGBTQ+ support, I think you're looking in the wrong realm, bud. I'd try Otherkin communities (which tend to have overlaps with some LGBTQ+ groups) for companionship and support and need commendation. Anyway, I hope your soul gets the release it needs.
Welcome to the Forums BTW.
