>>3434518Gender expression has always been fluid, OP.
Not only has gender expression always been fluid, but fluid to varying extents for everyone.
Even people who do not identify as "genderqueer", "gender fluid", "agendered", "nongendered", "genderless", "genderfree", "neutrois", or "other-gendered"... are.
We are all expressions of both male and female genetic and formative experiences.
